Axel
The first thing you'll notice about this fight is that Axel is actually serious about fighting with Roxas, the whole area will be surrounded by fire and Roxas will call fourth the Oathkeeper and Oblivion Keyblades for you to dual wield by default.
There isn't really much strategy to this fight at all, Axel will dash at you with a huge burst of fire behind him, to dodge this just stay locked onto him with R1 and move out of the way. Be careful however because if you hit the walls of fire surrounding the area you'll get damaged by the fire.
When your locked onto Axel you get the chance to use the Burst Edge Reaction Command, use this by jamming on Triangle until the Reaction is over. This should deal some major ariel damage to Axel.
Later in the fight Axel will dash at you a lot faster, so you can't really tell what direction he's coming from. Just keep on Locking onto him and diving at him to unleash some combos on him and you should be alright.
