Thank you everyone for offering, we found someone now.
Are girl Link and girl Dark Link doing it? Dang, another Link beat me to the punch.
Oh well. I probably don't have enough patience for the cosplay contest (I don't like being cooped up all day in the green room).
Actually we need a pikachu and an annoying weeabo character, but we have a few people in mind. If we wind up needing someone again we'll make a new post.
I'm not sure whether it was at Sakura Con or Kumori Con, but there was a scary Pikachu mascot costume wandering around. And when I say "mascot," I mean a Pikachu head on a yellow, fuzzy, cylindrical body with no arms or legs.
You'd have to play it up a little differently, but I can see someone attacking that particular costume.
