Virtual Toy Chest's
XTerminators was a little known series that was made by LJN in 1985. Two different kinds of toys were made: Battle Bugs and Bump Bugs. The Bump Bugs were motorized robot bugs and would "magically rise up advance forward and attack on their hind legs" when they bumped into an object.
