Dimension 1 (John Smith 10)
Winston appears early in the show, being a slight ally to John, Gwen and Kevin, having a crush on Gwen. He eventually follows the canon series, being controlled by the Lucubra and the Diagon. However, he survives this experience. He briefly gains the Omnitrix. It became a running gag during his first several appearances for Gwen being the only one of the main heroes to remember who he was.
