So I am trying my hardest to get through all the games while resisting KH3. I am trying to unlock the secret episode. I have done all three on standard mode. I know the requurements for the final mix version is stickers on all three, Xehanort Reports, and keyslinger trophy. My question is for the keyslinger trophy do I only have to kill 9999 with only one character, is it the amount of unversed across all three, or do I need to get it across all three characters?
