Not sure what you mean. Saitama also was removed by Boros to the moon. Came back, used a serious punch to counter Boros' blanet buster. Used a serious punch against elder centipede and evil ocean water too. Yeah, Saitama is pissed now, but how does Saitama being pissed destroy his character? He hasn't been damaged at all by Garou, and even if Garou demands more effort, it will still end up with Saitama obliterating him, because more effort means little when Saitama has a virtually endless pool of energy to draw from.
With the moon kick, saitama came back in like seconds. And that's exactly the problem. We know that even if garou sent saitama to other planets with the gamma ray burst, he could get back in an instant. We have precedent for that.
But he didn't come back. Garou somehow managed to send saitama away long enough, and during the time saitama was gone, garou gave cancer to everyone, clashed with the no 1 hero, and has seemingly killed saitama's desciple who was arguably saitama's only relationship.
All that is on saitama's hands. Because he underestimated garou, or thought garou was still human and could be saved. And that is what my problem is. I don't think saitama has failed to out down anyone he actively fought with and that lead to loss of life. Sure, saitama arrives late, or his attacks causes destruction. But he gets the job done when others can't. That's been his premise as a hero.
But right now, he's just like a shonen protagonist, where they couldn't or didn't use their full power. And they lose someone and is raging. And then obliterate their foes.
And that makes saitama seem incompetent.
If Garou(granted he is a very skilled prodigy) with a little power from God can stall saitama for that long, then what's he gonna do when God gets involved.
Also about God....
Is he gonna get defeated this arc.
Because garou clearly isn't in control. God is influencing him. Even if he is not, garou got the power up to wreack havoc, and even clashed with and potentially could even defeat blast. He is a clear threat. And he has "killed" Geno's, causing saitama to get pissed. So why would he spare garou after all that. And even if he does spare garou and not completely vapourise him, saitama will come to know of God. From garou and from Blast. Do you think he'll just say "not my problem", " Or I'll deal with him later" ?.
Of course this is not a problem if they don't make saitama address Blast's presence and garou going full on evil. But that is not good writing. And that's not the only problem with writing that just this chapter has caused.
You could definitely just shut your mind off, suspend your disbelief and enjoy the fight and story as they disregard previously established facts and character. But opm was never about fights or art for me personally. It's the story that has kept me coming back for more. And I'm not liking the direction it's taking. If you do, you should enjoy it. But as I said, the next chapter or chapters are gonna be crucial. If One and Murata manage to write a good story with addressing and explaining all the problems and inconsistencies, that would be the best outcome.
