It took me a while 'cause I couldn't find the secret ending from kh II...not kh II FM.
So I used KH I, II and Birth By Sleep Intros, KH II "Sora vs Roxas" and KH II FM "Sora vs Roxas, boss battle", KH BBS Secret Ending and Final Ending, KH II FM Secret Ending, KH Deep Dive, Terra's Ending, Twilight Town 5° Day and the song New Divide of Linkin Park.
I know you may say that using Linkin Park is too common and stuff like that...But at least watch it.
in KH I just needed some elixirs and magic to use the sonic blade
I could easily tell when he was going to attack
and even avoid the heartless angel attack (though in both KHs that's easy)
in KH2 I had it hard when he bashed me in the air and then attacked with 100 hits and then used those dark spheres and finaly crushed me just with a simple attack
but in KH2 FM it was really easy with the limit form...I was surprised how easy it was even in critical mode...he didn't even used his max power, when he gets covered in darkness and starts flying around
but I like more to race with them at gold saucer...I guess you are raising a gold chocobo to get to the island where you can get the strongest summoning "knights of the round table"...right?
