Does this death move the ranking?

Confirms the ladder

The higher-ranked entity killed the lower-ranked one. Record and ladder agree.

This is the rare Dragon Ball death that holds, and the ladder is already arranged as though it did. Fifth killed tenth, which is the order the ranking predicts, so nothing needs revising — but the manner is worth stating, because it is the franchise's whole economy in one move. He does not out-hit the thing. He is stalled for by two other fighters while a planet hands him its energy, and the shot lands because somebody else bought the seconds. Note also what did not happen: the death was never wished away. Kid Buu is reincarnated as a different person entirely, which leaves the original dead and the record intact — unusual enough here to be worth marking.

The longest depicted record anybody here has, and he is fifth because several of the entries above him have scored on him directly. Ultra instinct is the real thing — a state the narration describes as moving without deciding to, and which the panels back up by having him evade things he is not looking at. The screen and the page agree about him more consistently than about anyone else in this franchise.

He destroys the planet he is standing on, on screen, with survivors escaping only because somebody teleports them out — one of the few unambiguous large-scale kills in the run, and it happens rather than being reported afterwards. Everything after him operates at a scale the story stopped trying to express in comparable terms, which is a fact about the story rather than about the feat.

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.
