I really wanna say Accelerator but objectively speaking the moon feat (depending on the damage done to the moon) probably points to a Saitaima victory here, but its close and could go either way.
it kinda looks like it did country level damage to the moon IMO
Country? Moon is the size (on the surface), around the continent of Asia. If we consider the sheer mass and size of the hole, what Saitama did is continent level, at least.
the hole is non cannon.
Lets not compare "continental" to the "moon."
Destroying the moon would be a step above continental level, just because the moon has way more mass and density than land surrounded by water.
And wouldn't Saitman be screwed against an opponent like Accelerator? Because Accelerator can reverse the vectors of whatever touches him and considering Saitaman is a close quarter fighter, that'd mean his demise.
The moonbusting feat of Saitama is actually continental level.. Eurasia has larger area than the moon.. and Telesma is something that accelerator shouldn't be able to reflect (as stated by accelerator himself).. while pure force is something that accelerator should be able to reflect.. I say Accelerator wins.. Don't forget the near infinite computation stated at the novel, which means as long as he is able to know the property of the attack it is possible to be reflected or redirected..
Can you upload that image of Saitama you used in your OP in the Saitama's image gallery? Thanks, we should fill his gallery with more images, preferably good manga shots. I'll approve your image submission in the image wiki queue.
