The Skull Twins are skull faced aliens from the Space Police III theme. They wear skull-shaped masks, and have a white face underneath. The only difference between them is that one of them has an eye on their forehead. They have the same mask of Craniac, but a differen face.
These cosmic criminal clones live for speed. They don't care what they're driving as long as it goes faster than everything else in the space-lanes. They've been busted for comet joy-riding, rocket hot-wiring, and trying to upgrade their Skull Interceptor with a stolen faster-than-light engine. It's a good thing there are only two of them out there...or are there?
