Arun Bahkti, the man who would become the Steel Hawk, was originally just a simple freedom fighter, attempting to combat the establishment in his native land alongside his wife, the mysterious Varna (who makes purple spandex look REAL nice). At any rate, his standard methods were apparently becoming less effective, so the man began looking for alternative ways to help his brethren.
He decided to become a 'professional terrorist'. Assassinations, sabotage, and more became his claim to fame, and the man donated all of his profits (after arsenal maintenance, etc...) to his fellow freedom fighters back home - wherever that was; the specific country that Arun hails from has never been revealed. And, over time, the man got really, really good at what he did.
Eventually, the man caught the gaze of the Club, a super-secret freelance arms dealer and terrorist organization (read: bad people), who wanted Arun to be one of their elite killers. The man liked this idea, since it paid a whole lot, and signed on with them on a sort of contract basis; in other words, he did his ordinary freedom fighter thing until the Club came to him with a job.
One particular job involved another man in the Club, one Fritz Krotze, who had failed time and time again to deliver a specific piece of hardware: the M.A.X. armor suit that was wielded by Jenny Swensen, who stole it from Krotze International facility (it was her father's creation, after all). After he bumbled three separate attempts to get it back, the Club wanted his head.
So they sent the Steel Hawk to get it.
He arrived in Krotze's home after his latest failure, and took the man hostage, eventually beating him to death when an opportunity to frame Jenny Swensen for the murder presented itself (she swore on national television that he'd get 'what he deserved'). Arun beat the man to a pulp with a steel baseball bat, in a pattern resembling a huge metal fist.
Jenny got arrested for the deed, but while she was in jail, her sidekicks tried to prove that she was innocent. Following the trail of leads, the five Troubleshooters found their way to Bahkti's stronghold, defeated the inherent booby traps, and found the proof they needed. Of course, they also found evidence of another dastardly deed that Arun was up to.
After dealing with Swensen, Steel Hawk was assigned to the assassination of Prime Minister Thatcher (from Britain), who was visiting Boston on the Christmas holiday. Using their hopped-up M.A.X. tech, the M.I.T. students raced to Boston to defuse the bomb that Arun had planted on the Christmas tree. They failed, but still got the Prime Minister out in time.
Studying his failure, Steel Hawk found out who one of the Troubleshooters was, via some analyzed video tape. He tracked the kid down, figured out who his friends were, and then planned to take them down (especially since they were friends of Swensen's). Wanting his revenge to be sweet, Arun put together a particularly nasty scheme to obliterate the team.
He started with Timothy Ferris, the super-fast hero who actually saved Thatcher, by taunting him with his guns until he donned his Fast-Back exoskeleton. Then, Arun launched a series of grenades at the poor student, who (while fast) couldn't react fast enough to dodge 'em all. He got blowed up real good, and doctors had to amputate his legs to save his life.
He then tracked down the others, using similar tactics, until he could corner Andy Meadows. Once he had the optics engineer at his mercy, Arun used his own Beam-Splitter weapon to burn a hole through his chest, killing him instantly. Enraged by this, the last effective Troubleshooter, the one with the super-strength harness, chased him off for a little while.
While he planned his next move, Steel Hawk went to get a Rolfing massage. Of course, the last Troubleshooters managed to track him down while he was unarmed, and Eduardo Giotti (the one with the Strong-Arms M.A.X. suit) beat him into a fine paste, almost killing him. Steel Hawk would have died, if not for his wife Varna, who rushed into the place and pulled him out at the last second.
Getting him to a neutral country, Varna then got ahold of the best doctors she could find, who told her that the man was broken, having severe brain damage and too many broken bones. She refused to believe this, however, and forced the doctors to continue treating him (offering them all the money they needed). That was the last we saw of Steel Hawk, however.
It is unknown if he ever recovered from the beating that Giotti gave him, as his further adventures have yet to be chronicled.
