Gwen Tennyson is the cousin of Ben Tennyson and the girlfriend of Kevin Levin. She is a human/alien hybrid originating in another universe.[1]


At some point in her life, she teamed up with Ben, Kevin, and her grandfather and became a plumber.[1]

Gwen accompanied Ben and Kevin to Japan, where Ben would make a commercial for Mr. Smoothie. When she met Rex, she seemed to be impressed by what Ben had told her about his abilities. Later, Gwen opened a portal to Rex's universe for Rex and Bobo to return home.[2]


Gwen is able to control a pink energy called mana, also known as life energy.[1] She can use this energy to shoot attacks, create powerful force fields for herself and others, and open portals to other dimensions.[2]
