The Return is the thirty-seventh episode of Ben 10.
A shuttle launch at NASA is interrupted by a purple lightning storm. This attracts the attention of Ben, Gwen and Grandpa Max, who hope to discover the origin of the alien werewolf and mummy. While at NASA, Ben runs into an ill-tempered scientist called by the name of Dr. Viktor. Surveillance tapes associate him with the purple lightning storm, and he's quickly shown to be in cahoots with the two creatures. Ben, Gwen and Grandpa Max encounter the creatures again, in addition to Doctor Viktor in his true form. Ben uses Snare-oh for the first time to fight the alien werewolf. Following a losing battle, the Tennysons split up: Max and Gwen board the space shuttle that Doctor Viktor launches and Ben follows Viktor as XLR8. The mummy's onboard the space shuttle, and Viktor sends the werewolf to New Mexico in a flash of purple lightning through use of a teleportation device. But as Ben confronts Dr. Viktor, the scientist reveals that he is not carrying out his own plan. Viktor revives his master, who, to Ben's horror, is revealed to be Zs'Skayr.
