Keegan is typically depicted wearing the Ghosts' tactical gear, including a skull-patterned mask during operations. He's lean and athletic, with a rugged military appearance. Like the other Ghosts, his gear emphasizes stealth, mobility, and protection rather than heavy armor. Keegan is one of the more reserved members of the team. He rarely wastes words and tends to remain calm even when situations become chaotic. He's highly focused on the mission and has a strong sense of loyalty toward his teammates. Compared with characters such as Logan and Hesh Walker, Keegan comes across as more experienced and emotionally controlled. He's often the kind of operator who quietly observes a situation before acting.
