Who Would Win?

Inspired by my question today asking whether Galactus could consume Borg Cubes like planets I wanted to make a whole thread where Avocados could ask the most important question in Nerdom: Who could take who in a fight?

Now some ground rules: Not every matchup has to be a violent one. For instance, “In a race between Sonic The Hedgehog and The Flash who would be the winner?” is totally valid and fun. Keep main questions as top level comments and keep answers as responses. Also if arguments start happening keep a cool and levelheaded we don’t want to upset anyone and flame wars are rarely fun.
