I also had trouble beating him the first time but the two ways to beat him is either use emerl's trap then his pow attacks and when he comes towards you do the trap attack until he dies and if he is blocking the trap jump and hit him with your pow attack, or the other thing you could do is go to the ruins and battle with sonic and tails until you have enough good attacks use them when you battle him...the skills you would need the most would be 1st, 2nd, 3rd, heavy, and aim attacks.

Ok this requires patince and a lot of time. beat very easy battles (like lots of phi's in
sonic story) until you get an ultimate move. i already have the ultimate upper attack. oh
