Silver Surfer
Superman
Both semi indestructible do-gooders with god like powers, but what if Silver surfer was like “Hey Lois want to have a cup of coffee or something? and after that we can go for a ride on my giant metallic surf board.” and Superman would be "oh hells no! You come into my house and try to pick up my woman, little tin dude i’m gonna teach you some respect. and than the possibly world/ solar system destroying battle would begin.
