If they have several 'secret characters' in MKD they will most likely be like normal kombatants, but remember how relentless the copy secret characters could be.... I think maybe after unlocking all the secret characters, beating the game with them, and then doing something else to reveal Super Secret Character thats as hard to beat as the bosses or even more so... he/she could be introduced in a in-game graphic sequence like "I am (insert badass name). Finding me is half the battle, but upon my reappearance your death will be at hand." Then something difficult has to be done to find the character. This character would have all original moves and fighting styles. Maybe more than three fighting styles. maybe like two weapon styles or something. Be quick and strong and only a truely great player could dream of beating this character. Upon defeating this character, which might take many tries, a huge reward should be given to the victor, besides being able to choose the character. thoughts?
