Ben Tennyson (Earth-1227)

Ben Tennyson is the wielder of the Omnitrix, an alien device that allows him to transform into many alien species.

Second Summer
Ben appears as he did in the Original Series but with his Omniverse hair and his soccer t-shirt and undershirt from Alien Force, as well as swampy green shorts.

Powers and Abilities
Ben access to at least 20 aliens, giving him a wide range of abilities.

Weaknesses
Ben is vulnerable if the Omnitrix times out. It usually takes him a decent amount of time to get adjusted to new aliens, making him unexperienced in their powers and abilities if he hasn't transformed into them yet.
