Can Saitama from One Punch Man be killed by the Death Note?
No, because no one knows Saitama’s last name.
That’s what the shinigami eyes are for.
So, yes, the Death Note can kill him.
Except you’re forgetting one thing. If the deathnote cannot kill in circumstances that are possible for the victim to die, it will default to a heart attack. Saitama cannot be killed by a heart attack and no sittuation fabricated could possible kill him so nothing will happen.
Why can’t he be killed by a heart attack?
Because he survived a guy who had the power of a black hole….I think if he had a heart attack he most likely attack it back.
Can I get a canon reason why he can’t get a heart attack?
We are talking about anime of a man who got insane powers just doing a 100 sit ups….you aren’t going to get shit.
So there isn’t a clear reason why he can’t get a heart attack. Ergo, it’s possible for him to get one. :D
We aren’t saying he can’t have a heart attack, we’re saying he would survive one.
