A lot of versus debates get decided by what a character has actually shown, not what their story jokes they could do. Imagine someone arguing a character wins because the author would never let them lose. That's not evidence, that's plot armor. Goku has demonstrated universal-scale power, extreme speed, and a deep toolkit: Ultra Instinct, instant transmission, energy sensing, and counters for nearly any fighting style. Saitama's best feats are impressive, but his "one punch" premise is a gag, not a measurable ceiling. If we treat narrative invincibility as infinite power, every debate becomes meaningless. By actual feats and scalability, Goku takes it.

Framing this as "can Goku beat Saitama" means we compare demonstrated combat ability, not authorial intent. The win-rate point is fair as far as it goes, but those wins came against foes nowhere near universal, so it doesn't prove an unbounded ceiling. If we accept "written as a gag" as an automatic win, no matchup is debatable. Goku has actual universal-scale feats, extreme speed, and counters like Ultra Instinct and instant transmission. That's evidence; "he's written invincible" is a claim about the author, not a measured feat.

The other side keeps treating an unset ceiling as if it's a proven high one. They're right that finite multipliers can't clear an undefined number, but an undefined number isn't a feat either. It's a blank. Comparing demonstrated combat ability, Saitama's best on-panel showings are nowhere near Goku's universal-scale feats, speed, and counters like Ultra Instinct. So "at best it's unknown" actually undercuts the AGAINST case, because the evidence we do have favors Goku. A character isn't unbeatable just because his author hasn't drawn the limit yet.
