One of my favorite things about this game is the interactions that Characters have with each other before they battle. Giving some of them specific interactions for specific characters I think was a smart move. So for all the other fans of this I decided to make a lists of all the character interactions. For any of the ones that I don't know feel free to add onto it here or just feel free to tell people what your personal favorite is.
