Movie Thor loses rather easily. Comic Thor can solo the likes of Dragon Ball, Sasuke by himself stands no chance.
Thor can only be bested by the midgard serpent. No other entity can defeat him in straight combat, only the forces of nature and Ragnorok can undo Thor.
Wrong Thor.
Pardon? Norse mythology Thor and Marvel Thor are the only Thors I know, I assumed OP was talking about the latter since he's more mainstream. if not those, then which Thor?
Norse Mythology, I mean, we always go with the original here. He's the stronger Thor, regardless.
