Hit him two more time with Big, then use team blast. Switch to Amy and smash the other box to get team blast, finish the first part of the battle with Big's power attacks. With Team Chaotix, hit him two times with Vector, then keep using Espio's homing attack until his weak spot turns yellow. Switch to Vector and use team blast. After that, attack with Espio's homing attacks while his weak spot is red. When its yellow, use Vector. With Team Dark, get Shadow's and Omega's level ups in the boxes on the left and right sides of the arena.
