Okay, there are two characters over at IMDB I have no idea about:

1. "Mouse" played by Joseph mazzello

2. "Havoc" played by Matt Gerald

I know that the HAVOC was a 1986 toy, and that the movie studio is most likely just taking liberties by turning a tracked-vehicle into a person (God knows there aren't enough characters in the G.I. Joe universe, that they have to go and turn a vehicle into one for plot progression), but is it just ME or is "Mouse" not in the G.I. Joe lore at all (at least not in the Marvel or Sunbow part of it)?

Anyone know?
