An old, half-retired Crys Guardsman, Protofire no longer takes part in active combat without good reason. Often found wandering Cybertron assisting those who need it, he is reluctant to give his name, but will very frequently give advice if it is sought. His alternate mode is a solar-hovercraft, like many of the Crys Guard, and he wields an energon spear with a millennia of experience.
