The scenario is thus: you are facing down a god-like being whose powers are impossible for you to match. They are infinite in their potential. Thus, the only way to overpower it is with something beyond that.
This counterattack is usually reserved for a character that is omnipotent because this is the only kind of character who could believably have 'infinite power'.
Not to be confused with Up to Eleven, There Is No Kill Like Overkill, or Readings Are Off the Scale. Tentatively related to My Kung Fu Is Stronger, but only applies if the being your kung fu is stronger against is an omnipotent being. See also Even More Omnipotent.
The Infinity +1 Sword does not (usually) work this way.
- Three examples of this are shown in the Yu-Gi-Oh! anime:
- First, Yugi Mutou, to defeat a monster with an infinite attack, brings out all three Egyptian God Cards, then sacrifices two of them to make the third one — whose power would've already gone to infinite by the two sacrifices — even infiniter.
- At the end of the Doma arc the Big Bad, Dartz somehow managed to summon a monster with infinite attack points. Yugi responds by having two of his monsters attack, bouncing the attack between them until it reached infinity and then having a third monster attack to exceed infinity and destroy Dartz' monster.
- It's worth noting that in the original version, the reason that Yugi's Knight of Destiny won was because even though it had infinite ATK (the same as Divine Serpent), it also had an effect that prevented it from being destroyed by battle, so when the two equally powerful monsters battled, only one was left.
- During the show's Memory World arc, to defeat the Big Bad Zorc Necrophades, one of Atem's priests (who resembled Yugi's grandfather) summoned Exodia, a monster who was apparently so powerful (in the anime, his total ATK was infinite), he needed to be split up into five pieces. Even so, Zorc exploited the fact that Exodia needed the priest's life energy to remain manifest, draining that energy in the fight while he remained More Than Infinite thanks to his power being sustained by the darkness.
- In the real Yu-Gi-Oh! trading card game all of the examples above would lose to The Wicked Avatar, whose ATK is equal to the ATK of the strongest monster on the field plus 100. This is put to the test when it's used in the Yu-Gi-Oh! R manga; it's able to dominate virtually everything used against it, including Kaiba's Blue-Eyes and Yugi's Slifer the Sky Dragon (an Egyptian God whose power level is variable depending on the number of cards in its controller's hand, and who can reduce an opponent's monster's ATK and DEF by 2000, when that monster's summoned, an ability that, of course, did nothing to The Wicked Avatar). It was only taken down by Yugi's Obelisk the Tormentor, after it uses its effect to power up its ATK to infinite. The game physics for the manga actually follow real-world mathematics and consider "∞ + 1" to still be equal to "∞", meaning both monsters are considered to have equal ATK and, thus, do each other in.
- This was bound to happen eventually on Tengen Toppa Gurren Lagann, the Trope Namer of Beyond the Impossible. In the final showdown, the effectively omnipotent Big Bad throws a Big Bang at the good guys. One of them then absorbs the attack (via Heroic Sacrifice) and channels its power into the good guys' Indescribably Humongous Mecha, making its power More Than Infinite and allowing them to finish off the enemy.
- In Digimon V-Tamer 01, Taichi and Zeromaru discover a level of Digivolution beyond Ultimate, appropriately named Super Ultimate. (Note that the "Ultimate" level is called "Mega" in earlier translations). This makes one conversation in the English dub of the first series Hilarious in Hindsight. When Miyotismon becomes VenomMiyotismon, a Mega-level Digimon, The Team had up until that point, only seen Digimon as high as Ultimate (or what was called "Ultimate" in the dub) and were incredulous that there would be a level beyond Ultimate, saying something to the effect of "What is he, then? Super-Mega-Ultimate!?"
- An absolutely extreme example occurs in A Certain Magical Index, when Touma Kamijou does battle with Fiamma of the Right. Fiamma possesses the Holy Right, which grants him complete omnipotence and infinite power. Touma possesses the Imagine Breaker, which can negate anything Touma sees as not normal, including attacks with infinite power. Fiamma assimilates the Imagine Breaker into the Holy Right and succeeds in going past infinite power twice over, becoming "He Who Is Above God". However, this unleashes The Invisible Thing, an entity so powerful and destructive that even the now-exponentially-infinite Fiamma is reduced to cowering in fear of being devoured by a presence that is beyond even that. Then the Invisible Thing is itself outdone by yet another power within Touma, which dwarfs the power of The Holy Right, the Imagine Breaker, and the Invisible Thing combined.
- The cosmic hierarchy of the Marvel universe runs on this trope. Cosmic Cubes (and the beings created from them), for example, have explicitly infinite power, but Celestials are multiple levels of infinity beyond them. The Celestials themselves are several rungs below the cosmic abstracts like Death and Eternity, who are powerless against a wielder of the Infinity Gauntlet, which is itself weaker than the Living Tribunal. Of course, the Living Tribunal is merely a creation and servant of the One-Above-All.
- In the comic Superman: Red Son, Superman is trapped by the Green Lanterns who construct a box made out of infinite layers of other boxes. Superman still breaks out though, with just one punch.
- Crisis on Infinite Earths is a story about a really powerful bad guy destroying an infinite number of universes one at a time. Because he's just that powerful!
- Magic: The Gathering has many infinite loops that can allow a player to, say, gain infinite life or deal infinite damage, and lots of rule space is devoted to making sure the game doesn't blow up when two of those loops collide. Essentially, "infinity" translates into "whatever really big but still finite number you want", so if your opponent comes along with another infinite loop later on, they can choose a number bigger than the one you chose.
- Infinite damage loops tend to end when the thing they're damaging runs out of whatever it is that damage depletes (life for players, loyalty for planeswalkers, or toughness for creatures), or when someone renders the damage irrelevant.
- Infinite loops that perpetuate themselves without any input from players (such as three Faceless Butcher creatures without any other creatures in play, which will repeatedly exile each other and return each other to the battlefield) which don't incrementally progress toward a win condition instead result in a draw if no player can interrupt them.
- At the end of a Star Trek: The Next Generation novel trilogy based on the history of the already-omnipotent being Q, he is forced to absorb the equally-powerful Calamarain to become a More Than Infinite composite being to fight off another omnipotent, yet insane, being; the explanation given was that depriving an omnipotent being of his grasp of reality makes him even more omnipotent, essentially meaning Q had to become More Than Infinite to stop a being that's already gone More Than Infinite. (This is not series canon, by the way).
- Kamen Rider OOO explains that OOO's name is an infinity symbol plus an extra loop; OOO is powered by Greed, the ability to have everything there could possibly be and still want more. Despite this, his actual power at any given moment is finite, limited by how many Core Medals and Cell Medals he has.
