Shiro of the guild Log Horizon is not someone I would like to fight, nor would I want to face a team led by any living Calculator.

All fear the great and mighty nerd!

In all seriousness, though, it'll probably be a while before the teams actually end up running into each other.  By that point, we'll probably all have an extra power point or two, which can have major effects on a character's skillset.  And of course, the team dynamics would come into play: can the villains get along together?  Do the heroes function as a group?  Hard to make matchups when one RP hasn't even started yet :P

If it does come down to a fight though... well, I came to this site via the Arena.  *cracks knuckles*  I know how to play that kind of game.
