Glen is African American with short brown hair and brown eyes. He is extremely muscular and apparently never wears a shirt. In Karate Blazers, he wears orange pants; he wears dark green in Sonic Wings.
The invincible wrestler with thunderous fists
Glen's personality is much the same in Karate Blazers as it will be in later Sonic Wings 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.
Similar to Gill, he is a character from "Karate Blazers," a 28-year-old black man. Gill's fellow student of martial arts, he battles for the same reason. The upper half of his body, always naked to the waist (why?), is built with conspicuous muscles. He is a quiet and serious guy.
-Sonic Wings 3 Strategy Guide
Glen and Gill are searching for the kidnapped daughter of their fighting master, along with certain documents which were stolen at the same time. They have apparently rented the P-61 the team flies; Glenda is the plane's owner and seems to be the one navigating and flying it. Glen is rather full of himself (despite the strategy guide's claim that he is reserved), and he appears to give orders to the other two Blazers.
The guys claim that the stolen documents contain a homing device, and they relay its signals to Glenda in order for her to guide the plane. Nevertheless, they fail to find the missing girl; in their single-player ending, they question a soldier of the organization they've defeated (presumably Fata Morgana or the Hildroid). . . only to find out that they were pursuing the wrong evil organization all along. They don't seem to mind, though.
The Blazers fight with Mecha-Keaton in two-player mode. They seem surprised at his appearance and aren't sure who he is at first. Keaton likes to boast that as a robot, he doesn't show the Blazers' human weaknesses; however, the trio doesn't seem to envy his situation. After the final boss battle, Keaton's plane blows up, but he manages to escape by ejecting his head. The Blazers rescue him, but then their plane explodes too.
Glen and Gill appear if the player defeats Lar or Do-ni Revision using Angela in single-player mode. Glen and Gill witness Angela's plane crashing, then Angela's clothes fall off to reveal that she's wearing a corset. The humiliated Angela beats up Glen and Gill for "peeking."
