I used a Sigma 6 snake eyes and a random piece form a ML figure for the cannon. I made the mask from a rubber ball and a ginger ale bottle (its see through but I don't think you can see from the pics). I painted her with the gravity suit and made weapons for her... super missle, grapple beam, charge beam, and a glow in the dark screw attack.
Genius!
P.S. I want one of those arm cannons with attachments though....lol
