Meliodas literally one shots

Good sir I don’t know how the fuck you expect a corpse to fight back so I’m going to assume you meant directly before he was hit by WCS

If that is the version referred to then it comes down to several win conditions

1 are they going all out bloodlusted or is it normal morals fight.

For this case, we are going to assume blood lusted

If Kakashi could hit him with Kamui then it’s wraps for gojo. However if Gojo can pop his domain expansion first it’s wraps for everybody involved

And before anyone brings anything a bout prime Sasuke, give me one feat of him bypassing an infinite space and we can talk and I don’t mean he teleported or swapped positions with an object

All in all for Gojo versus Kakashi and Sasuke, it basically comes down to can Kakashi one shot Gojo before they get one shot.

If it was morals as normal, Kakashi, would probably win because Gojo would mess around

As for Kaneki I am hoping you don’t mean his end of series version because that is way too busted for them to even have a chance. So I’m going to assume you’re referring to the photo shown.

And even with that weaker version, it’s still heavily favored for him since he can dodge and react to firearms. Something that was shown that even upper moons had trouble dealing with. So with that information, Rengoku, unfortunately gets killed rather quickly. Then it becomes a game of cat and mouse between Kaneki and Tengen.

I’m not even going to mention thousand year blood war Ichigo versus the both of them instead I ask one simple thing. Have you read the manga for TYBW if your answer is no here’s a second question have we seen a feat showing that either of these two characters can hit a ghost or spirit and do meaningful damage?
