Was debating with someone in a YouTube comment section about Saitama's supposedly infinite power, and made a relatively long reply about it. I might as well post it here too since it's obviously relevant to OPM. Also for context I made a comment before that saying that there are already 3 people he hasn't instantly beaten in one punch, and 5 in total that have survived his punches.
"That doesn't mean he has infinite strength. And the point of my comment is that the joke of him one shotting people has already been broken. By that, I mean that the joke people always mention is that he ALWAYS one shots people. The fact that there are people he hasn't one shot on SEVERAL occasions has already made the joke of him one shotting people inconsistent, and thus destroys the argument that it's the point of his character to always win in one punch.
And don't say "he intentionally held back to keep Boros alive". He literally was surprised and opened his mouth while saying "Ah" when Boros got up after his first punch, meaning he didn't expect Boros to live.
Now, to explain his normal punches further, it's not that Saitama is intentionally holding back his blows, it's that he's not trying, nor is he restricting the power of his punch on purpose. He's just lazily throwing his fist forward without putting any actual effort into it. That's what his normal punches are. But if someone can survive his normal punches, that means they can survive the normal amount of power he puts out. And even if the power of said punches is as small as 0.000000000000000000000001% of his strength, that still means his strength isn't infinite."
