Team: Young Avengers
Brief Bio: The son of a Kree warrior and a Skrull princess, Teddy's mom escaped with him when he was a newborn to Earth.  Since the conflict between both alien species was extremely hostile.  Teddy however grew up on Earth unaware of his alien heritage.  Instead he was considered a relatively normal kid.  He played football and basketball in school and got good grades.  However in high school he not only found out about his kree and skrull powers, but also his homosexuality.  This ended up leading to him connecting with his first boyfriend Kevin.  Kevin was nice to Teddy but was manipulative.  Especially when eventually he found out about Teddy's shape shifting powers and had him use them for their personal gain.  Teddy didn't realize this until one night Kevin had him pose as Tony Stark to go into the mansion the Avengers used to use as their base, where Kevin wanted to steal from it.  Teddy though, a superhero fanboy at heart, refused and after a fight watched Kevin storm off threatening to expose not only Teddy's homosexuality, but his powers to the rest of the school.  In his fit of anger Teddy's powers truly kicked in, and he threatened Kevin serious harm if he did such a thing.  Shortly afterwards, he found out about a group of young superheroes and it was through them he met Billy Kaplan, aka Wiccan.  Who he fell for and has been dating ever since.
