The 3 inch tall Martian Manhunter 3D Plastic Car Emblem should not be exposed to fire. I'm not sure if Martians just have a weakness to it or if it is psychosomatic, but just to be on the safe side...keep him away from such things! Instead of putting on a normal bumper sticker, why not call on the compassionate soul of J'onn J'onzz and the Martian Manhunter 3D Plastic Car Emblem? He can stand toe to toe with Superman and match wits with Batman!
