When I go to go fuse things in order to get characters or power ups, king kai responds by saying that I lack the item fuaion numbers. I have fused items before, and it worked. But one day I forgot to save after I fused. So it all disapered. The next day I went to play, and noticed that the previous character has been missing. So I thought that I could just refuse him, and get him again, but king kai said that I lacked the item fusion numbers. Now everything I fuse, he will respond with that phrase. Unless the combo is no good. Please respond to this, I want to unlock everyone and all of their upgrades.
