Ben Tennyson from my WIP fanfic.
Like Gwen, Ben's spark was triggered after Granny Verdona judged them to be without it.
Ben's Anodite energy was what the omnitrix bonded to. As Ben grew in age and strength, so the strength of the aliens he could access increased.
As long as he wears the omnitrix, Ben's Mana is tied to it and he cannot actively use his Anodite heritage.
When Ben's body is destroyed, however...
This was a lot of fun to do, even though I fail at all sorts of things. Anatomy (his feet are TINY) is the worst, but I also bungled the play of shadow on his body (I had the vague idea that the front would be exposed to the least light... I drew his hair at the end) along with other things.
He's also very rough, maybe one day I'll clean this up.
His body is meant to look younger than his age in Ben10:Alien Force, as I'm going by the assertion by Verdona that Gwen would be a very young Anodite.
Kept his signature colours.
