I do this as well. I'd bet it's fairly common, given the controversial nature of the bio's. I am a devoted Christ follower, so my display reflects that. I have Granamyr with the snake men, since Satan is called the great red dragon in Revelation (although he has 7 heads and 10 horns as well). He and Draego-Man are both with the snake men since they are dragons, which are the Biblical word for dinosaurs, and since Satan is both a serpent and a dragon. And since giants are born of rebellious angels, all giants are with my Horde display. The FFM are placed in the groups where the vehicles they pilot are found, all with the good guys except for Dittstroyer.
