Bounty hunter. Guy in an all black mechanical suit that has four arms breaching from the back two with missiles/sniper shots in and two as thrusters to help me fly. I’d use a sniper and my helmet would have auto targeting and access to a large database which could help identify threats and how to beat them. My name would be Slideshot. Alternatively: a major crime boss who uses psychology to taunt my enemies (like riddler and his riddles) and they’d have clues to mess with my nemesis. My name would be The Shrink.
