Robby’s mini rivalry with this unnamed Iron Dragon Fighter.

Robby and the dragon first collide during the montage at the beginning of episode 7 that highlights Miyagi Do struggling, and sees the dragon winning against Robby due to Robby being distracted.

Later on in the sekai brawl, they cross paths again, but this time Robby is more prepared and gives it to him.

Though the dragon gets Robby in a headlock, Robby quickly breaks free and takes control again and opens the door for Sam to deliver her flying takedown maneuver to the dragon.
