I'm Owen and I can be reached at Little Masaouki on AIM. I'm on most of the day.
shadowkeyblade - Riku (Kingdom Hearts) - Riku comes from about a year after the end of Kingdom Hearts 2, when he and Sora were hanging out on the island and running missions for King Mickey. For those of you who don't know Kingdom Hearts, Riku is a boy who made the mistake of giving his heart to the Darkness when he was 12. He has been freed from this fate by his friend Sora, but rather than forsake all his memories and powers, he chose to walk the razor's edge between light and dark so he could use his powers to help Sora fight the darkness. His world has a lot of dimension hopping, so he feels confident that he can escape if he can learn more about this world.
He's a bit of an unusual case with Canon Puncturing. The actual video game is off limits, but the fact that he hangs out with Disney and Square characters is fair game.
I might pick up some more characters once the story picks up a bit. I'm thinking of Maito Gai, from Naruto.
