it gives a keyblade at kh2 that is much stronger than ultima its the nobo****y
atk 15
magic 15
and so you can get it:
first you must start a new game (on lv. hard) , then play with roxas till the struggle tournament and you must lose again setzer (last battle) then you get the warrior coin then you must!!!! complete jiminys diary 100% and all gumi ship routes 100%
(then you get the crown gummi)*sorry i dont know the word*
after that you must fight again setzer with sora 13 times (or more i dont know) then comes a cutscene where he says: "i have a nice information". you give him back the warrior coin and he give you the informatin about ghosts in the house where you fight again axel with roxas there are mighty nobodys defeat them all and xemnas speakink something then comes a twilight-thorn he is powerfuller then sephiroth(thats my mind) he makes three hits to you and you re game over^^really
defeat him and you get the nobody key easy isnt it^^
yeah that would be cool to be cloud or sephiroth in kh fm but i like sora more with his ultima as cloud with his sword. But could cloud everytime handle two swords it woud be great or better a fusion =Sora+Cloud = Sephiroth destroyer^^ or somthing like that yeah i think sora should fusion to a form with every fighter of the kh games(sora+Leon, Sora+hercules^^*joke*)
