Saitama (Serious) — power rating and matchups

These entries record encounters, feats and other events from the character's stories. Read each outcome with its version, sources and condition tags. Arena verdicts use the selected versions and matchup rules; a story result does not determine an arena result. This panel is for reference and does not feed the engine. The record is still being expanded.
