[هَـ-ђāŵĩ-ـَاوِي]

Warning: Contains spoilers for Dragon Ball Daima episode #18.Dragon Ball Daimahas finally done what no one thought possible: it made Super Saiyan 4 canon. For decades, Super Saiyan 4 has been cited as one of the best parts of Dragon Ball GT, if not the best, and even with GT being non-canon, fans have always wanted at least Super Saiyan 4 to be worked into canon in some way.
