Plater is slim and blueish in color. He wears golden armor and has a more serpentine build as opposed to the larger Jakarys. This is due to him being a different breed.
Plater is ruthlessly protective of his master, much like Jakarys is with Kotsu. He also protects the younger adoptive brothers of Ralph with a fiery passion. Overall, Plater is a far more ruthless and cold dragon, and a bit on the bloodthirsty side, though he has remarkable restraint.
