The hardest part of the fight is staying on the platform. Get used to his attack pattern, and when you know he's going to try to blow you off, get on the side closest to him. DO NOT try to use the dash to stay on, you'll just get blown off faster, or run too far and fly off! if you can endure the attacks, just use the sword and Roc's Feather to beat him up, whenever you get the chance.
