Hmm....lets see,the most important thing isnt the jeyblade but the level and the abilities you got,first of all you must at least have glide,quik run and double jump.Be sure that on your stock you will have many elixirs.
When he calls the heartless angel,be sure that you will stop him,you must have and the ability once more and second chance.
Equiping abilities is very very important you know,when he is teleporting and hits you several times be sure that you will cut those attacks or fly away from him,in other words,if you are too lazy to do all that,go on lvl99^^
Hope that that helped a lil^^
Good luck!
