Rocket Raccoon vs Caesar

vs

Who's smarter?

Rocket was inventing guns on the spot. Easily him.

Ceasar is a way better character and would kick his anus in a fight though.

Rocket would insert bullets into Caesar than use his remains for baby groot fertiliser.

Didn't Rocket withstand a direct blast from Ronan's infinity staff?

I forget the details of what he exactly hit him with but yes. Ronin did something to send Rocket flying unconscious.
