A gifted detective, veteran undercover operative, and formidable unarmed combatant, Cassidy was an excellent marksman and a competent amateur machine-smith, well-versed in combat strategy & tactics, and teamwork drills, from his training at Interpol. An effective educator, organizer, and lobbyist, he was also an avid American country music aficionado and skillful amateur piano player. As Cassidy, he wielded conventional firearms, sometimes loaded with explosive "micro-bombs." As Banshee, he wore synthetic costuming designed to resist air friction, usually including underarm wings that helped him glide on air currents and his own sonic waves. The "ribbons" on Banshee's costume (a visual trademark of the character) aid him in his flight.
