Inter-World Dueling! Describe one of your characters. Other commenters will respond with a character who would make the best foe.

~~Shamelessly ripped-off~~ Inspired from [this post](https://www.reddit.com/r/worldbuilding/comments/5fm3fw/interworld_matchmaking_comment_below_with_a/) Note that it's not a character that would win, but the one that would make the most interesting fight.
