Characters / Undertale Mettaton
- Actually Pretty Funny: During the "quiz" section that introduces Mettaton, at one point Mettaton will ask you who Alphys has a crush on. Answering either Undyne or Asgore will work, but if you answer yourself, Mettaton will declare that while that answer is completely wrong (and Alphys will have an incredulous look on her face), Mettaton finds the arrogance of this answer to be so amusing that he still won't penalize you for it.
- Affably Evil: He's still a lot more "entertainment robot" than "killer robot"; he treats you like an honored guest on his show, and he shows absolutely no malevolence towards monsters. Subverted; he doesn't hate humans in general either (he actually adores them), he just wants to kill you to stop a massive war.
- Agent Peacock: Especially in his EX form, which has the looks of a Bishōnen, a near-perpetually-flirtatious range of facial expressions, attacks implementing his pink stilettos and heart-shaped core, and the honor of being arguably the toughest pre-endgame boss. Even before it's introduced, he's vain, flamboyant, cross-dresses during the opera segment, and by all accounts has a fixation on the finer things in life while also demonstrating that he's clever, charming, and competent.
- A.I. Is a Crapshoot: The long and short of it is, the "killer robot" thing was an act set up to make Alphys look cool, but then he decides to kill the protagonist anyway, to save the rest of the human species (and get famous above ground in the process). Ultimately... it's a subversion, because his intelligence isn't actually artificial.
- Ambiguously Bi: His similarities to Alphys and his flamboyant glam rock demeanor imply this, but his sexuality is never confirmed either way.
- Anti-Villain: He is set-up to be a Noble Anti-Villain first, as he never tries to stab you with your back turned and you can't actually die from any of his segments, before he is revealed to be a Well-Intentioned Anti-Villain that wants to kill you to stop a massive war, and to make himself a celebrity on the surface. Also goes in hand with Villain In Name Only for first not being evil to begin with, and that him desiring to kill humans is far from the truth.
- Arc Villain: He is this in the Hotlands section of the game, especially when he takes his kid gloves off and starts hiring other monsters before trying to kill you himself.
- Arm Cannon: He gets a prominent one as Mettaton NEO on the No Mercy run. Not that he ever gets to use it.
- Attention Whore: The number of shows he apparently runs and some potential NPC dialogue implies that he's almost literally always performing, and at the end of the Hotland section of the game, he drives Alphys's plan Off the Rails and attempts to steal the player's soul partly to get a bigger audience than he already has by taking his career to the surface.
- Awesome, but Impractical: In-Universe, as he clearly likes his Mettaton EX form very much, but due to the form's "inefficient" power usage, he can't stay in the form for very long until his battery power conks out. He gets better by the end of the game after getting fixed by Alphys. It's still unknown if the power problem got fixed or not.
- Bad "Bad Acting": Somewhat invoked. For the most part, he seems enthusiastic and competent, but after the tile puzzle, he's clearly sick of the charade and of Alphys botching her lines, and he seems to just stop trying altogether.Mettaton:(after getting shot by the protagonist) OOOH! OOOOOOOOH! YOU'VE DEFEATED ME!! HOW CAN THIS BE, YOU WERE STRONGER THAN I THOUGHT, ETC.
- Bad Boss: Zig-zagged. Burgerpants affirms that he's terrible to him at least, and if he becomes king of the Underground, anybody who doesn't like him just... disappears, with the implication that he's getting rid of any dissenters. However, see Benevolent Boss below.
- Beauty Mark: When he's in his EX form, he has a rivet near his eye that essentially resembles one.
- Benevolent Boss: Talking to a few of his other employees after killing him on a Neutral Run reveals that he was a rather kind and well-liked boss. Therefore, it seems he was only a nasty boss to Burgerpants, and even then, he might have distorted the truth a little bit. There's also new dialogue added in the 1.001 version which implies that Mettaton has a thing for Burgerpants, randomly asking him to try on new themed promotional outfits, even though according to Burgerpants, most of the time nobody else has to wear them and some of them he had to wear just because Mettaton "felt like it".
- Big Brother Instinct: He's very protective and supportive of Napstablook, his cousin, and they're probably the only character he openly cares for. In addition to calling you out if you reject Napstablook's friend request, them calling him during the Mettaton EX fight makes him lose the will to fight you.
- Big "YES!": Gives out a voiced one when he transforms into his EX form.
- Bishōnen: His EX form. For a robot, he does look rather handsome.
- Bishonen Line: His alternate form is basically a glam rock star.
- CAPS LOCK: His speech is written in all capital letters, to give it a robotic feel. Once he changes form, his text appears normally. He still uses all-caps in some sentences, implying his previous No Indoor Voice was mostly affected.
- Cat Smile: He pulls a few smug ones here and there in his EX form.
- Chainsaw Good: He seems to enjoy them enough to feature them regularly in his cooking show.
- Clipped-Wing Angel: In his normal, rectangular form, he's totally invulnerable to the player's attacks. Not so in his EX form, which can be damaged easily and has terrible battery life to boot. His No Mercy run form gets this even worse, being his hardest-to-reach form and met with a lot of self-hype, when literally all it can do to you is potentially die throwing you out of the No Mercy run.
- Combat Sadomasochist: If you choose to fight him in a neutral run, every hit you land against him results in him moaning and pulling an....interesting◊ face. Once you knock some of his limbs off, he stops doing this.
- Combat Stilettos: His humanoid forms have some killer heels. One of his early attacks even attacks the player with them in the form of legs with heels that start/stop moving when the player shoots them.
- Crapsaccharine World: How Papyrus describes the Underground in endings where Mettaton becomes ruler. See Cult of Personality below.
- Crush. Kill. Destroy!: Seems like his goal at first. It's all an act. It actually turns into an outright inversion, since his goal after dropping the act is actually to take the human's soul in order to prevent the barrier from being broken and save the rest of humanity (and become a star on the surface).
- Cult of Personality: In some neutral endings. If Toriel and Undyne are both dead, he becomes ruler. Anyone who does not worship Mettaton "goes missing".
- Cut the Juice: Subverted: That isn't an off switch on his back.
- Deadpan Snarker: To a truly hilarious degree. He'll never let an opportunity to snark at Alphys' or the Protagonist's expense pass by him.
- Declaration of Protection: Despite his self-absorbed nature, he cares a lot about his cousin, Napstablook, and his friend, Alphys. It is more explicit in the No Mercy run, where he states there are people he needs to protect.
- Didn't Need Those, Anyway: Unless the player manages to defeat him very quickly, his EX form will lose its arms and legs during the battle.
- Does This Remind You of Anything?: His efforts to become corporeal are highly reminiscent of transitioning.
- He even goes through a pronoun change— Undyne, his former neighbor, only calls him "they" when you call her from his house, Napstablook's house, or the farm, implying that "they," "them" and "their" were the pronouns he used before he was able to transition into a robotic body. In all forms of his robot body, however, he goes only by "he," "him," and "his." Since Mettaton disappeared without a trace and didn't keep in touch, there would be no way for Undyne to know about the pronoun change. Another possibility is that ghosts, being incorporeal, go by "they", "them", and "their" by default, since all ghosts in the game are referred to this way, and only begin to identify with a specific gender once they've inhabited a body.
- Early-Bird Cameo: Papyrus' randomly generated maze puzzle is Mettaton, this is more noticeable if you go back to see that it's gone. This also changes the context of it "messing up", it wasn't a technical error, it was Mettaton screwing with Papyrus.
- Eating Machine: Has a cooking show, even. Justified, he's actually a ghost.
- Even the Guys Want Him: Oh, yes. Papyrus calls him his "favorite sexy rectangle," and remarks that he wishes he lived in Hotland so that he could meet him. This is after Papyrus mentions about three times before how glad he is he doesn't live there...
- Evil Gloating: Seems to enjoy doing this quite a bit.
- Exact Words: Because you defuse all six of his lesser bombs, the Big Bomb will not go off in 2 minutes. It will go off in 2 seconds.
- Expy: Appearance-wise, he bears more than a passing resemblance to Claptrap of Borderlands fame.
- Face Death with Dignity: If you kill him on a Neutral path, he'll Go Out with a Smile, coolly (and dishonestly) saying Alphys can fix him and wishing the player luck, thanking them for giving him the chance to "perform" for them. Even when you one-shot him in a No Mercy run, he'll go out with a smirk and a dry one-liner (or mocking you, if you flubbed the requirements for a No Mercy run at the very last point where it's possible to do so.) On the Pacifist path, he acknowledges that his EX form has a Fatal Flaw in its poor battery life (not that the batteries can't be replaced until Alphys fixes the problem off-screen later). He postpones his debut in the human world to remain a cultural icon in the underworld, thanks everyone for tuning in, and lets his battery life finally run out.
- Foregone Victory: You cannot actually lose during his quiz; his penalty attack always inflicts half of your HP rounded down in damage and thus cannot actually kill you. You also cannot die to any of his subsequent challenges along the way to the MTT Resort; if you fail, either he does something that spares you at the last second (such as abruptly going to a commercial break) or Alphys steps in to save you. As it turns out, this is all because Alphys and Mettaton rigged the entire journey so that she can come off as a hero. Mettaton's EX form averts this trope, as by then he's gone against Alphys's plans and is trying to kill you for real. Played straight once more with Mettaton NEO, as he not only goes down in a single attack but also doesn't even bother to attack you.
- Four-Fingered Hands: With White Gloves. Word of God says he's confused over how many fingers humans usually have because all of his knowledge comes from media, including western cartoons. He actually has several gloves with different numbers of fingers.
- From Nobody to Nightmare: In the King Mettaton ending. Goes from a nameless snail farmer to a tyrannical king.
- Glass Cannon: Mettaton Neo: 90 ATK. 9 DEF. He dies in one hit; if you failed the No Mercy requirements at the end of his battle, he even lampshades it as he dies by saying that Alphys should maybe have worked a bit more on his defences. Subverted, as he doesn't even attack you, thus rendering his stats irrelevant.
- Glory Hound: A very sympathetic version. Since he still gets a soul by killing you, he knows that he'll be able to get through the barrier and get fame in the human world as a hero. He does honestly want to help both species, and by helping his ratings, you get him to realize you're a worthy hero to stop the war yourself and people already appreciate him, so he allows you to go on in peace.
- Good All Along: Although he acted as if he wanted to kill all humans at Alphys' request, he actually wants to save humanity... which means he has to kill you so Asgore won't get your soul.
- Graceful Loser: In the neutral and pacifist routes, he takes his defeat remarkably well. In the pacifist route, he even has a bit of a So Proud of You moment.
- Gratuitous English: His "OHHH YESS!" is always written in English in the Japanese translation of the game. Additionally, quite a bit of what he says is written in katakananote mainly used for words imported from other languages, which carries the same meaning.
- Harmless Villain: During encounters with Mettaton, no matter how much you fail at his tasks (answer every quiz question wrong, stand still during the bomb defusing segment, etc.), it's impossible to lose to him, and he announces his defeat and goes on his way. This is a hint that it's all a charade planned by Alphys, and Mettaton's not supposed to harm you. Once he admits the truth to you, he isn't so harmless.
- Haunted Technology: Entering the house next to Napstablook's reveals his backstory. He's a ghost - Napstablook's cousin, to be precise - who had dreams of making it big in show biz, and was given a robotic shell by Alphys.
- Having a Blast: He loves using bombs against you, both in the newscaster segment and in battle.
- Heart Drive: His heart-shaped core.
- The Hedonist: From what we learn about him as a person, he takes full advantage of the level of lux and self-indulgence his role as a high-profile performer living the dream affords him.Undyne: I don't really like that guy. ...But I admire his lifestyle!
- Heroic Sacrifice: In the No Mercy run, it's implied that part of his real reason for fighting you, even though he knows he can't win, is to allow Alphys and other monsters to escape.
- He's Got Legs: Lampshaded in his EX form. Praising Mettaton's legs during the essay portion of his boss fight nets you a ratings bonus. And in the ending when he forms a band with Napstablook and Shyren, his legs are noticeably the only part of his body not covered up by the metal box he wears."Who needs arms when you've got legs like these?"
- Hidden Depths: Underneath Mettaton's massive ego, biting sarcasm, and extreme self-centered nature, there's a genuinely smart entertainer who really does love his fans with all his heart. (...SOUL?) Enough that he chooses to give up going to the surface so he can stay in the Underground with them. There's also a small moment in the True Pacifist epilogue that speaks volumes about what kind of guy Mettaton is. The lion-like monster that said Mettaton's wearing a dress made him feel like maybe he could wear one, too, now has a dress on... specifically, the very one Mettaton was wearing. Turns out, Mettaton gave it to him! He's also a pretty good boss, according to everyone at the MTT Resort (besides Burgerpants), and really does care about Alphys and Napstablook.
- Hour of Power: His EX form has inefficient battery consumption, meaning he'll eventually run out of power (and lose his limbs) if the fight drags on.
- Hypocritical Humor:
"Oh my! This is supposed to be a family-friendly show. Now stand still while I murder you!"
- If you swear during your essay response, he responds...
"What the hell is that? Sounds... sexy."
- And if you answer Toby instead:
- He'll also call the player character "conceited" if they claim Alphys has a crush on them.
- Impossibly Graceful Giant: He's not exactly gigantic, but he's incredibly agile and graceful for a metallic robot.
- Incoming Ham: Every time he makes an entrance.
- Intrigued by Humanity: He started a human fan club before he became Mettaton. He's shown to have an infatuation with humanity, as most of his entertainment is based on shows humans love and his EX form is the most humanoid being in the Underground. He only wants to kill the Child to prevent a war between humans and monsters.
- It's All About Me: He's ridiculously egotistical and self-indulgent. If he becomes king, he makes the Underground into an Egopolis.
- Jerk with a Heart of Gold: An arrogant, smugly antagonistic attention hound he may be, but he cares quite a bit about his cousin Napstablook, is good enough friends with Alphys to have initially agreed to his Killer Robot role in a scheme for her sake, and seems to genuinely appreciate how much his fans value him. Also, in the No Mercy route, he confronts you even though he knows he can't win, and implies that part of his real reason for fighting you is to protect Alphys.
- Killer Robot: As called out by his cooking show, "Cooking With A Killer Robot". Again, this is all an act.
- Large Ham: Easily outperforms Papyrus and Undyne in this department. Then again, he is an entertainment robot...
- Last of His Kind: In a sense, after his fans become really upset over his decision to leave, he then realises that humans already have stars and idols, while he's all the monsters have to look up to as a celebrity.
- "Metal Crusher" is his standard battle theme, "It's Showtime" sounds for his intro cutscene and cooking show, and "Oh! One True Love" reappears as "For The Fans".
- "Death by Glamour," his boss fight theme, draws from both of them. It can actually can be heard in the game long before the actual fight with him. The opening part is heard in the opening of CORE, the "chorus" can be found in the "chorus" of his previous theme Metal Crusher, and the bridge can be heard in It's Showtime!, Live Report, and Death Report.
- While he has "Power of 'NEO'" for his NEO form, it's really just a remix of "Battle Against A True Hero".
- Lightning Bruiser: Bordering into Confusion Fu territory. Mettaton's battle style is unusual and based on being varied, fast, and flashy to entertain viewers first and foremost. Trying to both entertain and battle, he's a competent fighter.
- Logical Weakness: Mettaton is originally a ghost monster, given a physical form by Alphys. As a ghost, he was incorporeal and thus immune to nearly all attacks. However, as Mettaton, he's as prone to death as any other corporeal monster.
- Mad Bomber: In his 'Newscaster' scenario, he traps you in an area full of bombs disguised as several seemingly innocuous things, like a glass of water and a dog. In his EX form, many of his attacks involve bombs as well.
- Mean Boss: When it comes to Burgerpants in any case, not so much towards his other employees. He made a whole album purely dedicated to telling Burgerpants how bad at his job he is.
- Meaningful Name:
- True to his occupation, Mettaton is very much aware of genre expectations and the fourth wall as it exists in the game. A ton a' meta, in other words.
- His name could also be a reference to Metatron, an angel whose name abbreviates to MTT and who was a human before being transformed into an archangel.
- Mirror Boss: Notable for being the only boss that has a SOUL present during the fight itself. In a reversing of roles, you can attack it just like how bosses attack your SOUL.
- Morality Chain: It's implied that Alphys is one of these to him, as shown in one of the Neutral endings. In particular, the Neutral ending where he becomes tyrant ruler of the Underground has him mention that he wanted Alphys to help him rule, only to discover that she went missing. It's heavily implied that, had Alphys not disappeared and possibly committed suicide, Mettaton would have become a much better leader due to her advice.
- Mr. Fanservice: Mettaton EX certainly doesn't play down this sort of appeal. Ironically, his default rectangular form is considered this in-universe, being, in his own words, "more photogenic," and Burgerpants admits to purchasing (non-working) "kits" to make himself more rectangular.
- Multiple-Choice Past: Depending on what route you took. In a Neutral/Pacifist run, he was made as the entertainment-type rectangular robot and upgraded to his EX form later. In a No Mercy run, he was created as an anti-human robot first, then given his rectangular form later when he was re-purposed as an entertainment robot. Of course, his speech in his No Mercy encounter could be baloney. He takes a noticeable pause when he describes his rectangular form as "more photogenic" and despite having a fierce and imposing-looking appearance, doesn't attack you at all. Also, why would his old form be called 'NEO' (new)?
- Musical Spoiler: Mettaton NEO's battle is hyped up to all hell, receiving a pimped-out new form and crazy stats to deal with you. That is, before you one-shot him. But the fact that his theme, "Power of NEO", is only a thirty second loop should tip some off that it's going to end quickly.
- My God, What Have I Done?: If you Spare him, he receives a call from Napstablook and clearly feels guilty about leaving them behind. It happens again in the neutral ending variant where he becomes king of the Underground; with Alphys "missing," he expresses regret over how he treated her.
- Nigh-Invulnerability: His rectangular form is described to be impervious to attack by the CHECK option, and the only way to defeat him is to flick his switch so he becomes Mettaton EX, which has low defense and a limited power supply. Despite this, he appears to be fazed when you attack him in the dungeon segment, which is actually foreshadowing that he was merely playing along the entire time, as he is immune to your later attacks before you flip his switch.
- No, You: If you throw out an insult or cuss-word during the essay portion of his last battle, he throws it back in your face with "This essay is supposed to be describing me, not you."
- Older Than They Look: His bishounen form looks early twenties. However Napstablook indirectly confirms the snail farm existed before 'their best customer' Toriel left. If Sans's implication she has been gone a hundred years is correct, the ghost cousins are over a century old. If addition, Undyne and Papyrus' UnderNet profile names end with the years they were born ('92 and '95 respectively) while Napstablook's ends with "22." If his username follows the same trend, it implies the cousins were born sometime in the 1920's.
- Oh, Crap!: Has a mild version of this when his limbs blow off during your fight. He tries to play it off as a Major Injury Underreaction, but his stuttering gives him away.
- One-Wheeled Wonder: In his usual appearance, where he balances his rectangular body atop a single comically tiny wheel.
- O.O.C. Is Serious Business: Mettaton during your last fight against him. He starts as his usual self shamelessly proclaiming himself the brightest star of underground and soon-to-be of the surface. As the battle drags on he'll start to lose his composure and outright call the player out for their "weakness". Also in the ending where he rules the Underground, he becomes somber and saddened over Alphys' disappearance and wishes he had a chance to treat her better.
- Opportunistic Bastard: When Alphys asks him to play the heel against the human, he plays along so he can derail the plan later. In the ending where he becomes ruler, he starts by unironically thanking you for your "hard work" (i.e. killing Toriel and Undyne) as this paved the way for him to seize power.
- Peek-a-Bangs: Mettaton EX has his right eye covered with hair. Mettaton NEO, keeping with the subtle theme of left eyes being shown in serious situations, has obscured his right eye.
- Percent Damage Attack: The penalty laser he uses during his quiz halves your HP and as a result cannot actually kill you.
- The Perfectionist: An unusual Sanguine example. He pushes everyone who works for him to attain his high standards, and refuses to accept anything he doesn't deem to be as good as 'how they do it on the Surface'.
- Pet the Dog: He really cares about his cousin, Napstablook and his old friend Shyren, enough to go into showbiz with both of them in the Pacifist ending. If you spare him but kill every other boss (leaving normal enemies alive), he becomes king and has a statue built in Alphys' honor, admitting that he was cruel to her.
- Pinocchio Syndrome: Hinted. He is so fond of humans he founded a fan club celebrating them, and the body he asks Alphys to build for him is the most humanoid thing you see underground, being basically a metal Bishounen. It even has its own visible SOUL.
- Plot-Irrelevant Villain: Mainly from a meta perspective. In the Pacifist run he's the odd one out of the main characters; while the other major bosses are meant to present serious questions about the player's morality, with Mettaton what you see is what you get - a silly, if deeply layered, drama queen. Averted, however, in the Genocide run; see Threshold Guardian below for why.

Mettaton uses the Red Soul during the quiz show and beginning the battle after the Multicolor Tile Puzzle, and the Yellow Soul in all other circumstances.
- During the quiz show, if the protagonist answers incorrectly, Mettaton fires an unavoidable electrical beam that halves the protagonist's HP.
- After the tile puzzle, if the protagonist does not press ACT → "Yellow" right away, Mettaton drops boxes from above in a set pattern, with gaps in between.
- Note: All attacks do 6 or 7 damage per hit assuming no armor and LV 1.
Mettaton EX's attacks all consist of an arrangement of several objects:
- Copies of Mettaton's legs stick out from either side of the box and scroll downwards. They can be either moving inwards and outwards or not move; this can be controlled by shooting them, which stops the moving legs or causes the motionless legs to begin moving again.
- Copies of Mettaton's legs quickly emerge from the side of the screen. An exclamation mark appears in the area that they will appear in before this attack is used.
- Small rectangular Mettatons glide down on umbrellas. As they reach the bottom of the screen, they begin to toss hearts that are embroidered with the letter M: they will often toss a second set upwards just as they are leaving the bottom of the screen.
- Bombs marked with a plus sign travel downwards, which explode into plus-shaped blasts when shot with the yellow soul. The blast spreads slowly enough that it can be dodged by moving aside, as long as the bomb was detonated sufficiently far away. The explosions can destroy blocks and trigger other bombs.
- White squares marked with black circles travel downwards (and sometimes side to side), which are broken by a shot from the yellow soul.
- The Bullet Board contracts to four blocks wide, and lines of bombs and white squares with black circles (usually three bombs and one square or three squares and one bomb) travel downward, then a "rewind" button appears and they travel back upward in the same formation, with destroyed parts remaining destroyed.
- Long segmented arms resembling Mettaton's travel downwards, with sliding orange-yellow boxes along their length which, when shot, toggle the arm between retracted and non-retracted states (thus, they should only be shot once).
- Mettaton's heart emerges from the square on his waist and shoots lightning-bolt shaped projectiles either in a circular blast formation or single linear shots (which only happens when he loses all of his limbs). Firing at his heart ends Mettaton's attack earlier; not shooting his heart still causes his limbs to fall off due to being a scripted event. Contrary to popular belief, attacking Mettaton's heart this way does not count as FIGHTing him. When only his torso exists, his heart will fight for him for the rest of the battle until he is either killed or the ratings reach 10,000.
- A disco ball appearing from the top of the square projecting laser beams in either blue or white, which can be toggled in color by shooting the disco ball. They rotate at a variable pace: when blue, they count as blue attacks, when white, as normal attacks.
- The Bullet Board contracts to being only two blocks wide, and pairs of objects rain down, consisting of a bomb on one side and a solid white block on the other. The block can only be destroyed by shooting the companion bomb, and so it is necessary to shoot the bomb and quickly move under the block to avoid damage from the downward part of the explosion.
- Mettaton calls for a "union-regulated break" and the words "Happy Breaktime!" appear on the Bullet Board. This is a Gray Attack, and simply a free turn. It always comes after two two-width block / bomb attacks in a row, and Boasting works normally even though it is impossible to get hit during this turn.
Mettaton NEO uses no attacks.
Mettaton Quiz Show
Alphys is present during this battle and uses her hands to shape the correct answer's letter. If Alphys does not provide an answer, it means any is fine. Answering any questions wrong causes Mettaton to halve the protagonist's HP. Attempting to hurt Mettaton in this form does not work; the screen always displays "Miss."
To defeat Mettaton EX without killing him, one must survive until his arms and legs are blown off and achieve a show rating of 10,000 or more; if his limbs are not blown off, a show rating of 12,000 or more ends the battle. While the protagonist waits without acting, the ratings go down. The ratings stay at 3,001 at the minimum until the protagonist does something. Mettaton's limbs fall off regardless of whether or not his heart is shot, but shooting it ends his turn earlier. Ratings can be boosted in several ways:
- Getting hit gives a violence boost of 10 to 50 points.
- Shooting anything during Mettaton's turn.
- Using the FIGHT option to directly harm Mettaton results in him either biting his lip or sticking his tongue out while saying "Yeah," giving an Action boost of 300 points. Further attacks cause him to grin visibly but give fewer Action Points.
- Eating food sold by Burgerpants gives 300-500 rating points, but the Steak in the Shape of Mettaton's Face gives 700 points instead. Eating Junk Food gives the 'Eating garbage?!' penalty of 50 points. All other consumables have no effect.
- Equipping a different piece of armor gives 1,500 points as long that piece has not been worn previously during the fight.
- Using the Stick causes it to be thrown at Mettaton. He catches it in his mouth and ratings boost by 700 points. Repeating this action gives 1 point. Using the stick after Mettaton has lost his arms and legs instead gives 1,400 points.
- Using the Boast action causes ratings to shoot up during Mettaton's turn, but taking damage costs 100 points and stop the rating spike.
- Using the Pose action gives 100-1000 points, inversely proportional to the amount of health the protagonist has left.
- Using the Heel Turn action increases the aforementioned violence boost to 100 points. This is more of a risk as it requires the protagonist to get hit.
- Early in the battle, Mettaton asks the protagonist to write an essay about what they like most about him.
- Writing "LEGS" earns 350 points, which is the highest amount, being the 'correct answer.'
- Writing "TOBY" earns 300 points, Mettaton saying that Toby sounds sexy.
- Writing "DANCING" earns 250 points, Mettaton saying that he is self-taught.
- Writing "ARMS" earns 250 points, Mettaton commenting most people talk about his legs, but embrace them for their writing anyways.
- Writing "VOICE" earns 200 points, Mettaton commenting that he has the voice of a siren.
- Writing "HAIR" earns 200 points, Mettaton saying that he uses metal hair gel.
- Writing anything that does not meet any requirement earns 100 points.
- Writing certain words like "fabulous," "beautiful," "radiant," and "personality" make Mettaton comment on them.
- Writing nothing earns 80 points. Mettaton is not surprised that the protagonist is speechless.
- Writing certain swear words results in the loss of 150 points, which causes Mettaton to exclaim that the show is family-friendly.
- Writing a word that Mettaton deems insulting prompts him to tell the protagonist that this is an essay about him, not them.
- Writing a lot of random gibberish and letters with no sense results in Mettaton being impressed that the protagonist wrote so much about him, even though he does not understand what they said.
If Mettaton EX is spared, he appears only as his torso and head when the game returns to the overworld view. This happens even if the protagonist ends the fight before his limbs fall off. However, if he is killed, he appears in his original box form in the overworld view but damaged.
For those who plan on killing Mettaton, methods that decrease ratings should be used, as the ratings may hit 10,000 before the protagonist kills Mettaton. Methods that decrease ratings include writing a curse word during the essay and eating Junk Food, so bringing a full inventory of Junk Food is advised. Waiting between turns also steadily decreases ratings. However, it stops decreasing after a certain point.
Despite claiming to be a human eradicator, Mettaton NEO does absolutely nothing. Any non-missing attack instantly kills him as he is scripted to take between 900,000 and 999,999 damage, no matter the strength of the attack. There is no way to spare Mettaton NEO, meaning that the point at which a Genocide Route cannot be aborted occurs before fighting him when the last random encounter is killed.
Contrary to popular belief, a weak attack does not revert to the Neutral Route. Only failing to depopulate Hotland and the CORE completely causes the game to revert to the Neutral Route.
