Termite-Nator

Termite-Nator was a termite based badnik created by Dr. Ivo Robotnik as a means of eliminating the Knothole Freedom Fighters by eating them out of house and home. It ate anything made of wood or paper, and gets larger as it eats. Robotnik used a phony ant-farm business to trick Rotor into acquiring a Termite-Nator. Before long, it had eaten all of the furniture and almost all of the books, and it would have eaten the Great Forest had Sonic the Hedgehog not tricked it into eating a log with some extra-thick pancake batter. With its jaws disabled, it was easily rewired into a metal muncher, and sent back to Robotropolis. It's final fate is unknown. (StH: #5)
