Yeah, as the author said, that's not really a knock-off, it's an original creation. If HasTak had ever engineered a "Crotchmaster" then it would surely be a running joke in Transfandom like Heinlad and his Spark-nads.

Afaik the only Ankylosaurus Transformers are Bazooka and Slapper (which is a repaint of Bazooka).

Heh... richard cranium...
