Morals On, random encounter, fight in abandoned Metropolis, Win by KO or capture.
Fighting him would be like when he fought Kaine, although in this version it would be a much less intelligent version. This would still be a good fight to watch, if Ironman could get a hold of any of Booster's tech he could take it easy, until then Booster would have the advantage in a tech fight. I'm inclined to go with a draw but just for the sake of picking, Iron man 5.5/10
In a random encounter IM has nothing that will get through Booster's shield. Boosters blasters when pushed can take it to doomsday. Though to be honest I see this as simple as Booster reroutes his force field through the blasters ( which he's done a few dozen times in battle quickly) and then simply contains IM in one ( capture one of the win conditions)
