Not as difficult as the Shocker & Vulture fight, but still a small challenge. Your main focus should be on Rhino until he's down; lure him to one of the big objects that you can pull down and pull them when he gets close. Then unleash a barrage of hits and repeat.
Once Scorpion enters the fray, you'll have to dodge more often as he'll shoot poison at you from a distance, but keep your focus on Rhino. You can use your gadgets to help keep Scorpion paused in his actions, but once Rhino goes down, you'll fight Scorpion which ends quickly as he has a "glass jaw."
