I note that this thread is many many years old, so I dunno if it's dead in the water.
THAT SAID, if people wanna play Animorphs characters, it is an option at a MUSH I played on many years ago. It's called "Multiverse Crisis MUSH." A MUSH is a text game, like a MUD but less combaty, more role-play...'y? Anyway, theme there is some crazy crap happened and now lots of universe came together. I know some people don't like that kind of game, but it's a place where you could play, like... Jake or Visser 3 or what-have-you if you so desired.
Just direct a Telnet client to telnet://eddie.rpg-works.net:5001
MUSHclient is the client I use, and it's free. Well, the client I USED. I don't play these games much anymore. No time. Anyway, thought maybe someone could have fun with it, so I'd throw it in there.
