I use iTools to access App data but currently it's not supporting iOS 8.3. In the App data there will be temporary files which is in game data such as in-game art, island blah blah.
You need to deploy the character you want and it will available there. Also the enemy unit work too but some character Enemy sprite and Our sprite are different because of tattoo for example Ace enemy will have ASCE tattoo while our Ace don't have any.
See the example below for Mr.5 everything are almost the same except a small detail.
