Keith's Fantasy Club
King Rex is a homage to the 1985 Dinobot Grimlock.
In May 2013 Keith's Fantasy Club teased images of microcassettes with the names of species of prehistoric reptiles on them.
In June 2013 a shadowed image of the prototype of King Rex was posted to the Weibo page for Eagle's TF.
Concept art of King Rex and Bladeback was previewed at TFcon 2013's Third Party Panel.
