Season 2 Intro

Ben gains access to two new aliens, whom he calls "Cannonbolt" and "Wildvine."

An alternate reality is shown, in which Gwen finds the Omnitrix instead of Ben.

Eleven-year-old Kevin Levin returns and becomes a secondary archenemy to Ben.

The master sorcerer Hex returns, with his niece Charmcaster.

Gwen reclaimed her "Lucky Girl" hero name after buying the Keystone of Bezel, which further increased her natural combative abilities to superhuman levels. The five Charms of Bezel are recreated but again destroyed.

Ben's ninth alien form, "Ghostfreak", turns rogue and attempts to become whole by taking the Omnitrix.

Vilgax allies himself with Kevin and succeed in removing the Omnitrix from Ben's wrist.

Because of Gwen's quick-thinking, Ben regains the Omnitrix but loses access to the master-control function.
