Saitama vs. Vaccine Man is actually the opening fight scene in Episode 1 of One Punch Man, not Episode 2. Here's a quick breakdown of that epic (and hilarious) battle:


---

Scene: Saitama vs. Vaccine Man

Episode: 1 – “The Strongest Man”

Enemy: Vaccine Man – A powerful, monstrous creature born from humanity's pollution.

Vibe: He gives a dramatic monologue about nature’s wrath… then Saitama shows up.

Outcome: Vaccine Man powers up into a huge, terrifying form...

Then: Saitama ends it with ONE PUNCH. Instant KO.

Saitama’s reaction: Totally bored. He mutters, “...not again.”

Classic One Punch Man tone: intense buildup, insane art and animation—then pure comedy from how overpowered Saitama is.
