Off the scale
One of these two was never ranked, so this cannot move a ranking it is not in.
No movement, and the victim's placement was argued from this in the first place. Sitting off the scale is not a promotion here; it records that authority and force are separate quantities, and that the first can be removed by parties who never conceded it existed. The death is the evidence *for* that reading rather than a challenge to it — which is the most useful thing a pairing can do when neither party is in a position to move. Worth flagging that a killing of this magnitude rests on `stated` testimony alone.
The Beyonders killed The Living Tribunal in New Avengers (2015).stated
Named as the killers of the Living Tribunal and the cause of the incursions destroying the multiverse. — 2015
The multiverse ends, leaving one patchwork world assembled from the survivors.
They killed the Living Tribunal, they killed Celestials, and then they collapsed the entire multiverse to a schedule, universe against universe, until one was left. Nobody else here completed a plan that size. The contested tag is for the obvious objection: they barely qualify as characters, they have no dialogue, and their motive is never explained. The wreckage is still on the page.
Introduced as the arbiter who maintains balance across the multiverse. — 1967
His body is discovered dead on the Moon, with no explanation for two years. — 2013
The multiverse's judiciary, and the clearest demonstration on this page that rank and power are different things. He outranks nearly everyone in Marvel and was still found dead, killed by beings who did not recognise the court.
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.
Both entries carry their full receipts on the Marvel ranking — 4 citations between them.
