When Gwen's elder brother Ken disappears while in Santa Mira, California, both Grandpa Max and Ben's team converge to look for him. Ben's team finds another alien weather machine working to keep the area in a state of perpetual rain - the perfect condition to raise xenocites, alien parasites that take possession of humans. Surrounded by DNAliens and threatened by a HighBreed, Grandpa Max readies an extreme solution while Ben's Omnitrix reveals a heretofore unknown ability - it can talk. Written by statmanjeff
