Hi there, this a system/list that is here to show the threat level of what your character, item, verse, and so on may be in the Undertale AU Multiverse. It is a list divided up into seven tiers that each go up in power. You may add an individual, group, AU, or verse, and others that you think falls into a layer by adding them to the list of known users. Linking users towards their pages, if they have any is optional, but preferred. Make sure to add credit to the person or people who made the character.

There can be only one character for the one pop-culture example. You may only add a pop-culture character if that character is considered popular enough among the AU fandom. You may replace the pop-culture character if the individual is either; more popular than the current example or if the person/monster is a better representative of that tier. You may also replace the images of the layer if they are a better representative of that tier or to fit the pop-culture example.

You are allowed to use this tier list for any character; it's ok, but don't force it on others.

  • DeltaDust!Sans(Trigger!Maniac); Although not being able to destroy AU's himself, within a short time (but not too short), DeltaDust can leave an entire AU empty of it's characters. Leaving an AU empty of it's characters can be equaled into erasing an AU itself, and if a problem causer like that isn't stopped, there will be some major problems the multiversal gods need to fix. Also, if said AU is left out for WAAAAY too long, it will soon slowly fade away, which is equal to destroying an AU itself.

If you feel a slight hint that something is wrong while traveling the AntiVoid... please, please contact MultiSwap Sans using the rose garden. It's story... it's gonna happen all over, again and again. Until it's perfect. Until he's back. It will stop at NOTHING DO YOU HEAR ME?! NOTHING TO GET IT'S BROTHER BACK.

(Nearly all of hypothetical tnt yeeter’s characters that are tier 7 would go here)

Outerversal Threat (Unofficial)

TheseThese are characters which surpass Dimensions, and can destroy entire Outerverses.

  • Super duper hyper omega ultra giga tera mega yotta zeta sans ( Satan himself ) This being was made by satan, and even he fears his creation. This being can go into the real world, but only at a specific time after a specific ritual.

  • Fatal corruption sans can destroy multiple outerverses, I’m working on to make him stronger
    Omega404 he can destroy multiple outer verses if he so pleased he is the rival to Alpha404 (more he is still noyt complete so he might seem weak )
  • Corrupted reality!Gaster Omega404's creation a bit weaker than him (incomplete )

Cosmoversal/Numberversal Threat OR above(unofficial)

The max power a fictional entity can reach (can destroy everything in the fiction with just a blink)

  • Hyperdust Fatal Corruption Sans Well one of his blasters can destroy 30% of fiction and he can kill hundreds of outerversal gods in a blink so he fits here.
  • Gary Sue super secret form (Hypothetical TNT Yeeter) Imagine Gary sue except he literally has a portion of metaversal power. While his beyond form has some of the power of a creator in his secret form he has literally been blessed by TMY.
  • Extreme True Hyperdust Fatal Corruption Sans He is a very OP character, he can one shot fiction by blinking and he can also use some metaversal powers like he can create characters or tiers, however, he can be affected by very OP characters like core corrupted sans

The Beyonder (DarknessReaper9) He transcends The Fandom Entirely. Therefore transcending even Joke Characters and the like. Technically, this list isn't accurate to him, due to transcending the fandom. He can effortlessly defeat Outerversal Entities. His only real weakness as of now is authors, as they can still simply write him out of existence.

N.O.S.T.A.L.G.I.A TFO (Hypothetical tnt yeeter) Is low numberversal.

Fix: Read his page, he is incredibly powerful

Generic op character!Sans (Hypothetical TNT Yeeter) lol he can one shot beyonder lol

Beyond the 4th Walls (unofficial)

The maximum power any author or real being can reach. The final tier. No OCs can reach this tier.

  • The Players (IRL people) are usually the ones behind the Action of Chara and Frisk in Undertale, as well as Kris in Deltarune. They can modify both games to their own design if they're tech-savy enough.
  • Creators (IRL people) are the most powerful beings in the Fictional Omniverse. The most popular example would be Toby Fox himself, with his avatar as the Annoying Dog. Not only did they both created and destroyed all that was listed before them, but they also collectively control the fate of the Omniverse through their Tales.
  • Big Bang (Uh, well he is technically God himself but lets just say Well Heck) Big Bang surpasses REALITY itself. It created everything possible. And in UNIVERSAL MONOLITH form... I can't even explain what THAT can do.
  • The Meta Yeeter (Himself AKA Hypothetical TNT Yeeter) An avatar that became his creator because yes.
  • DarknessReaper9 The Critic. AKA a Very Buffed Spongetale Patrick. (Uh- His Parents?) Basically Just a writer who hates other writers' creations and also hates ships. He also likes some creations
  • oh look, a cookie!
  • wait what was i talking about again
  • TMY (Hypothetical TNT Yeeter) A metaversal being that is an author.
  • Ross the Turtle; The main form of Feartheunknown2104's SOUL. Being the SOUL of an Author/Creator, he has powers similar to that of Toby Dog's, albeit somewhat weaker. He can create new Universes, Characters, and even Multiverses by himself, but has much more difficulty destroying them. He exists most of the time in the TurtleVoid.

The true limit line would limit any further power, so this would be the final tier.

Characters with an unknown threat level (unofficial)

These are the ones with an unknown threat level or the ones that haven't shown their true potential(pls don't use this to create charecter strong as toby or whatever or don't say that iF hE sHoWs hİs TrUe pOwR ToBy wOuLd Die AKoeıctföofcgsgpd ext pls)

  • Coruapted Core Sans:he is able to chance his power level and the fact that he is a creator's vessel makes him beyond the 4th wall but he chanches his power level so he fits this unknown category being TheFlufyBoii03032000's avatar makes him absolutely beyond the 4th walls
  • Zer0 (SomeXtraArt): its unknown how powerful he can be but was able to destroy his timeline when his emotions consumed him
  • Dark Coruapted Core Sans:He would die if he used his true potential
  • Regresus:he has the same power level as dark corruapted core becouse he is damaged after the destruction of their universe

  • Extreme True Hyperdust Fatal Corruption Sans:if he would ever show his true power fiction is definitely going to be destroyed
  • ⚐︎💣︎☠︎✋︎✏︎☝︎✌︎💧︎❄︎☜︎☼︎ ( Well heck ) The anomaly's true power would most likely destroy maybe even the omniverse. They are the representation of evil and unrest in the fandom.
  • Extreme True Hyperdust Fatal Corruption Sans (possible power): his true power is unknown but he can now he can one shot the ISM by blinking and when he is sleeping but he was never taking the fight seriously so his true power is unknown
  • Void Demon Sans: This sans is unknown...????
  • Xerox!Sans His power level can't be determined because he can copy the abilities of any being even overpowered ones except with half the power, but that's still strong. He cannot die as long as the souls are not in their bodies he also has the abilities of souls and his teleportation is beyond everything except he can't teleport into reality however, I CAN EDIT WIKIS dumb author. as WELL as the fact I can manipulate any story I am in as long as I'm talking in 1st person, this can be taken temporarily by the Auth but I DON'T FLIPPIN CARE because my 4th wall ability is beyond all else *smirks, I can communicate with my past or future self in stories as WELL as talk directly to the Auth.
  • Crashed-666 Is a error sans but with a lot mor potential. Even tho he likes to joke about he can deal heavy damage to the multiverse if he wants basically wiping it clean of any annoyance in his way . He does this by crashing the code of his victim nullifying them so they cannot move,attack it even teleport since crash is the only one who controls their code at that point

A threat to reality, fiction, and all that exists and does not exist.

These characters have power levels unthinkable to our human minds. They are true eldritch horrors and can do nothing to destroy everything that does exist and does not exist. They need to be destroyed.


  • A user in a tier does not automatically mean that they will beat any row that is lower and lose against any higher layer. For example, a tier-two could win against a tier-three, and a tier-two could lose to a tier-one.
  • Since this list is merely describing someone's threat level, any character, whether it be a joke, serious, parody, and so on, can be added to this list/system.
  • If a character has shown inconstancy towards their feats, choose the best and closest to cannon feat that individual has done to decide what tier.
