The ultimate brain vs brawn battle. But if Superman is super strong, super fast, has super flight and is super invincible, why isn't he super smart. Is his brain the only thing unaffected by earth's yellow sun?
Some sources have Superman able to keep up (more or less) with Lex when it comes to science, but I think that's the result of the unfair advantage of Superman having access to advanced Kryptonian technology, where Lex has to come up with his inventions all on his own. *pets Lex*
