Cheats, Codes & FAQs
In Ultimate Battle Z mode, pick any of the Tag Team roads. When asked to choose your characters, pick the character you want to double the EXP gained from the battles you'll fight on the Tag Team road. Make sure to choose custom, and make sure that the character has potaras that can be leveled up with EXP. When asked to pick your second character, just pick the same character again, along with "Custom," just like you chose the first character. Now, when you win a round, you'll get double the EXP!
