Ben, Gwen and their paternal grandfather Maxwell Tennyson, spend their evenings fighting aliens on the streets of Bellwood. During a battle that involves chasing and fighting a robotic tank, Ben as Upgrade and Gwen argue about the best way to defeat it, resulting in Gwen utilizing her extraordinarily strong magic to cast a dismantling spell on the tank while Ben is still attached to it. Though this does defeat the tank, unknown to the group, it leads to a malfunction in the Omnitrix.
