Alien missiles are purple aliens with round blue eyes holding on to a rocket that is blasting forward.
There are two types of alien missiles, small and big. Small missiles hold a small missile with their tentacles, with their head located underneath the missile. Small missiles are deployed in great numbers, and will explode against whatever they run into, as all missiles will.
The second type of missile, the big missile, is not deployed as often as small missiles. The big missile is more longer a bigger then the small missile, and also has flaps near the booster. It is deployed much less in groups of small missiles, but has increased abilities of the smaller missiles.
Its increased capabilities include increased speed, so it gets to its destination faster then the small missiles, and being more stronger, giving off a bigger explosion, and more potent one to, when it explodes.
