Some of my favorite non cybertronians:
Lord imperious delirious: i'll say it again BW uprising turned this guy into one of the greatest villains we have.

Thundertron: bring on the Starseekers, these guys need to enter the IDW fiction

G1 Nimue: on of the most hilarious and kick ass characters in the cartoon.

Twilight Gleaming Mikaela: what the character should have been in the movies. The only female movie character who actually did something usefull in the movieverse and was a person instead of a pretty face that every teenboy was supposed to go wow over.

The Quintessons: one of the most enduring antagonists and for good reason. These sinister, weaponsdealers have been weaving plots against other cultures since the beginning of time. I wonder what they'll make of them in IDW
