A figure that is made with the Ben 10 Alien Creation Chamber, I used to have a lot of pieces but I was only able to find 1 figure missing an arm, so i'm improvised (the right arm). The Creation Chamber lets you mix and match parts from Ben's aliens so I made a skin of the one that I was able to find. I tried to make sure it looked like the toy and not like it was meant to be a real mix of aliens by adding the the the thing on the back that let you clip the body to the creation chamber and 2 screws. Also in the transparent arm you can kind of see the thing that holds the arm and body together so I added that and some other small touches. The alien parts that were used for this were:

Head: Alien X
Body: Swampfire
Left arm: Goop
Right Arm: Wildmutt
Legs: Alien X
