Ditto Tennyson

Dedrick Tennyson, or commonly referred to as Ditto since an omnitrix incident, is a main character in Ben 10.

Appearance
Ditto looks just like the transformation in the original series and Alien Force, but doesn't have the omnitrix symbol on his head/chest, and wears the omnitrix on his wrist. Also, in Alien Force, he is taller and his body is a bit more humanoid because he is now older. In Ultimate Alien, he has the Ultimatrix on his wrist and now wears a black suit with white gloves, white boots, a white collar, and a white cape.
