This was done by Royaljellysandwich as a commission featuring Gwen Tennyson from Ben 10 in particular of her from the episode "Game Over". She becomes like this for like a minute and gets turn back to normal. So I guess it was only for a gag but I love the idea of Gwen kicking butt as a Sumo. I really like how it came out.
I hope you enjoyed this and please comment and fave!
