Dragon Ball Sparking Zero's Roster of 182 Characters Is One Giant Dragon Ball Easter Egg
If the 182-character roster stirred something in your Dragon Ball memories, that's because it appears to be a callback to one of the episodes from the original Dragon Ball series. More specifically, you have to venture back to Dragon Ball Episode 84 which was titled "Rivals and Arrivals" in the English version of the show and helped kick off the Tien Saga.
