Okay, making your own character's doesn't mean you made a KAK, KAK is a feature in Armageddon, when you actually Kreate a Kharacter, so just because you came up with a character, doesn't mean you kreated one, simple enough?
In otherwords, just coming up with the idea of a character does not mean it's a KAF/KAK. It has to have been constructed entirely within the Mortal Kombat Armageddon Kreate a Fighter feature in order to qualify as such. It must be fully rendered in 3D and playable on the game, not just a 2d artwork on the computer.
