It didn't stick

The record shows a kill. It was reversed, so the ranking does not move.

Ainz Ooal Gown vs Climb

The killerAinz Ooal GownOverlord · rank 1
The victimClimbOverlord · rank 24

The widest gap of any pairing on this page, and the least that can be drawn from it. Twenty-three places separate the two; the lower one swung anyway, and the spell that had already stopped a dragon's heart stopped his before the death was taken back. Nothing moves, because nothing about the outcome was ever in question. The comparison worth making is with Gazef, killed by the same hand after refusing it in his own way, who asked in advance to stay dead. A swing at the Sorcerer King is a brave line in a brief row; it is not evidence for one.

The killer · Ainz Ooal Gown · rank 1

Momonga — the Sorcerer King

Light novelsnovelanimation

Killed Shalltear Bloodfallen, a level-100 built as a counter to everything he does, by planning the fight before it began: a super-tier opener, a bluff about mines laid in the air, and a guildmate's white armour worn through [Perfect Warrior] once her mana ran low — dropped at the end for the super-tier spell that killed her. Nothing else he fights is numbered near him. A Frost Dragon Lord dies to a single [Grasp Heart]; the Elf King, his mana gone against walls of skeletons, runs once Ainz has destroyed his Behemot; and at Katze Plains one super-tier spell kills seventy thousand men in seconds before the five Dark Young it calls up start on the rest.

Climb on the Overlord ladder

What this does not settle

One death in one work. It is the only place the record puts these two in the same room, and it is evidence about that meeting and nothing wider — not a general matchup, not a rematch, and not a ranking of its own.

The ladder above it is argued from everything either of them has been shown doing; this page is argued from one citation.

Where the two disagree, the disagreement is the point, and it stays visible rather than being resolved by whichever of them happens to be on this page.
