Ben 10 (2016, Coolot's version)

Ben 10 (2016) was a mixed bag but it did have some missed ideas, so this is how I would do Ben 10.

Differences

 * The designs are similar to the original series designs but tweaked to give a similar vibe to Omniverse.
 * [Ben having Omniverse's clothes (the white and green hooded jacket) and Gwen having the ponytail and the blue shirt]
 * The characters are slightly older, although a bit younger than their Alien Force selves.
 * The series has several casting references to other Ben 10 or related media.
 * Most notable examples include Tara Strong (who voiced Ben in the original series) now voicing Gwen, Ashley Johnson (who voiced Gwen starting with Alien Force) voicing the Charmcaster, Kari Wahlgren (who voiced the Charmcaster) voicing Frightwig and Tara Platt (Yuri Lowenthal's wife) voicing Kai, aside from Yuri Lowenthal himself double-roling as Vilgax.
 * Ben (and Albedo by extension), Grandpa Max, Dr. Animo and Kevin retain their voices from the classic continuity.
 * Kevin again has the focus on absorbing energy and using it since Albedo is the character with a negative Omnitrix.
