I was excited to show off my unique Gremlin custom... until I did a Google search and realized that a half dozen people already beat me to it. Yeesh.
Anyway, he is made from a head cast of Gremlin from the Hulk line. I used the end of a swizzle stick to make a new ball joint for the neck to add some movement to the Moleman body. The hands are from a Street Fighter figure.
I had fun painting the veins and detail on his ugly face.
Head: Gremlin head cast
Body: Moleman (Showdown)
Hands: Street Fighter (Ibuki, I think)
