Jojo's Bizarre Adventure's Golden Experience Requiem is conceptual.
"Gold Experience Requiem's ability is to turn anything, including his opponent's attack and willpower, back to the state of "zero". Hence, it is near invincible, as all "supposed" actions created by an opponent would have been reset (back to point zero). It is mentioned by Giorno himself that he is unsure of the exact workings and limits of Requiem's powers, but it has been shown that its range of influence extends from finger beams, surface contact, and to even being in the mere attention of Requiem."
Bleach: Ichibei's Ichimonji also returns everything to 0 at conceptual level, by stealing letters from names (sealed form) and in released form (shikai) it steals the entire name and in bankai it can give anything a name and the attributes. It won't physically turn you into a candy, but if he renames you into chocolate bar then you're conceptually going to be one. And Yhwach's "The Almighty" brushed Ichimonji off because Yhwach can see all of the future with it, and anything he sees is going to make him immune to it, also he can steal all power.
When Yhwach killed the Soul King it started crashing multiple universes at the same time.
