I found these two duck figures (with the white helmets) at Walmart last week. They are from a line of metal figures with various Harry Potter, Disney, and Marvel subjects. This one is GizmoDuck, apparently from the animated series, Duck Tales. They are quite large, but I think they look pretty good as heavy support robots.
I added an Assault Group bazooka to one of them and flame thrower to the other. This Frinx better watch out. Next time we play a science fiction Combat Patrol game the Ducks will be unstoppable!
