This is an entry in the TC7 Eurobricks competition, and was created to be like an 80's MASK toy.

Weaponry Transformation - Medium range missiles pop out at the back - Heat seeking missiles sit on the back skis - Side panel opens up to reveal small torpedoes on each side - Hood opens up to reveal two machine guns
