Changes

* The above sequence would repeat infinitely.

Infinite loops with net change have been seen a number of times in the anime:

===In the anime===

* In [[Yu-Gi-Oh! ZEXAL - Episode 098|episode 98]] of ''Yu-Gi-Oh! ZEXAL'', [[Yuma Tsukumo]] and [[Astral]] fused into [[Dark ZEXAL]] against [[Vector]], with the latter, who was blinded by rage, taking control. He equipped "[[DZW - Chimera Clad (anime)|Dark ZEXAL Weapon - Chimera Clad]]" to "[[Number C39: Utopia Ray V (anime)|Chaos Number 39: Utopia Ray V]]", granting it immunity by battle destruction and the ability to [[attack]] once again with doubled [[ATK]] whenever Dark ZEXAL took [[battle damage]] from attacks involving it. He then proceed to attack the higher-ATK "[[Number 104: Masquerade (anime)|Number 104: Masquerade]]", taking the first damage and triggering the first ATK boost. However, Vector [[activate]]d "[[Extra Hundred]]" in response to the second attack, so that "Masquerade" always had 100 more ATK than "Utopia Ray V". Astral didn't realize the danger, and continued to attack again and again, losing 100 [[LP]] each time, until he was down to 600. At that point, Yuma managed to cancel the fusion and promptly ended the turn, preventing the 500 damage of "[[Sargasso the Different Dimension Battlefield (anime)|Sargasso the Different Dimension Battlefield]]" from reducing their LP to 0. Had he not managed to, Astral would probably have continued the loop until he lost.

* In [[Yu-Gi-Oh! ARC-V - Episode 099|episode 99]] of ''Yu-Gi-Oh! ARC-V'', [[Declan Akaba]] activated the effect of "[[D/D/D Wisdom King Chaos Apocalypse (anime)|D/D/D Wisdom King Chaos Apocalypse]]" against [[Jean-Michel Roger]], which lets him Special Summon it from his hand by destroying two face-up Spell/Trap Cards he controls, those cards being "[[D/D Savant Nikola]]" and "[[D/D Savant Thomas (anime)|D/D Savant Thomas]]". Since "Nikola" was destroyed while it was in the Pendulum Zone, its effect let Declan return a "D/D/D" monster, "Chaos Apocalypse", on his field to his hand, and then place up to two face-up "D/D" Pendulum Monsters from his Extra Deck ("Nikola" and "Thomas") to his Pendulum Zone. Declan followed up with "[[Dark Contract with the Abyss Pendulum]]", inflicted damage equal to the DEF of a "D/D" Pendulum Monster that was returned to his hand. As the DEF of "Chaos Apocalypse" is 2000, this was enough to wipe out the rest of Jean's LP. Attempting to bypass his loss, Jean re-entered the Duel and took the 2000 LP intrusion penalty. Declan revealed that he would simply use the effect of "Chaos Apocalypse" to Special Summon it again, triggering the effect of "Nikola", and in turn triggering the effect of "Abyss Pendulum", which would deplete Jean's LP again. Realizing that Declan would repeat this loop each time he attempted to re-enter the Duel, Jean forfeited and fled.
