grimlock wasn't a dragon. it was moddled after a trex
the decepticon "dinosaur" was atleast something more similar to godzilla or or dragon.
As for me.. I've made a few... GoZiraBot G1 transformer "guardian" like Omega Supreme, moddled after Godzilla, autobot. i had other ones to fit the other TF continunity. I'll have to dig it up... had about a page discribing the TF stuff alone... before doing my transformer, tron, tekkaman blade, one must fall etc cross over.
