Glen is an African American wrestler with short brown hair and brown eyes. He is extremely muscular and apparently never wears a shirt. In Karate Blazers, he wears orange pants, but he wears dark green in Aero Fighters/Sonic Wings series. In Karate Blazers, Glen's personality is much the same as it will be in later Sonic Wings/Aero Fighters games: he is cocky and seems immensely proud of his physique. For his special attack, he pounds his fist on the ground, sending out a shock-wave to damage the enemy.
