Scarsguard has a tanned skin tone, two scars on his face, black eyes and a black goatee, with stubble across his face. He wears a guard uniform, with a star on his chest plate, spikes on his shoulders, and two spikes on his wrist bands. He also has a light blue helmet with a star symbol, a pair of yellow wings, and one yellow spike on top.
While their relationship is mostly unknown, Scarsguard taught her how to defend herself among other things. When the young Star beheaded a training dummy (as seen in "Freeze Day"), he was shown smiling at her action.
