Jennifer Bella Tennyson or known by her nickname Jen, she is an 18 year old woman who once saw a meteor crashing down on earth, and it was a watch known as the Omnitrix that transforms her into different aliens, she is pretty much a superhero now and she fights a lot of bad guys and stuff.

(This is pretty much gender swapped Ben Tennyson but older for some reason, don't ask me I found some comic named Jen 10 and they said she is 18)

Appearence: Long brown hair, green eyes and white shirt with black sleeves
