You've seen the Spider Devastator in that one Exo-Force product. (Sentai Fortress?) This is my own version of it, since I didn't really like the one it gave us.
The new and improved spider devastator. One arm that has a spear, and the other is a more flixible arm. It includes six legs. It has a pack on it's back that has a blaster, cameras, and an engine for tight situations.
