The Wasp is a subtle reference to Jeff "Joker" Moreau from the Mass Effect universe, specifically the comic book Mass Effect: He Who Laughs Best. The Joker has a number of health issues and only proved his competence as a pilot by hijacking the SSV Normandy.
I like the idea that he could be part of Falconrazor's crew as a pilot. Yes, he's missing one manipulator and a micro-claw, and with a broken optic, essentially useless and worthless, but still a pilot.
Falcon might have hired Wasp purely by chance, having witnessed him prove his professionalism in a rather risky way while trying to find a team that needed a pilot.
War criminal. Formerly an Autobot, he betrayed them and defected to the Decepticons, where, ironically, he himself was cruelly betrayed and thrown into space like trash. Now a bounty hunter, he despises both factions. He's quite a bitchy, arrogant, and haughty soldier with a nasty personality.
