With Kekki Gennai, the easiest answer is to do something like what I did with Will and the Sharingan - if it's really wanted to be used, just make it a family trait. However, I would recommend keeping that to SEGA characters as the main set, and anyone else has to inherit it. As for the elemental Kekki Gennai, they can just fit into one of the advanced elements, the one they were made for. DBZ techniques would be similar, but all techniques would be stubs until they reach a high level of detail. How's that?
