Inside Man

A DNAlien who is a man loses his memory, because the Highbreed have took over it. Ben, Gwen and Kevin meet up and they find that he's Tyler. They find a stolen key from the DNAliens. Ben transforms into Chromastone to look at the key. Tyler breaks the truck open. Then, Ben tranforms into Humongousaur (dinosaur type). He picks it up and then a tractor beam comes towards them. Then Ben is Jetray and the DNAliens take Tyler. Jetray grabs him and turns back into himself. Tyler doesn't remember or like being a DNAlien but then Ben's Omnitrix repairs Tyler and he becomes a human. Then they find out what the DNAliens are up to.
