Dragon Ball FighterZ just dropped the Kefla DLC, but someone over on Twitter thinks they may have cracked the code on who's coming next.
Although Arc System Works teases out the same silhouettes for upcoming DLC (not much help there), there are coloring schemes that are tied to each entry. For Kefla, that color was red, an obvious nod to her outfit. But it stands to reason that the rest (silver, blue, green, tan) will follow suit.
As such, Twitter user Senyu posits that silver is Ultra Instinct Goku (yet another Goku!), blue is Majin Vegeta, green is Demon King Piccolo (the progenitor of the main Piccolo you know and love), and tan is Master Roshi. You know what? Other than Ultra Instinct Goku, I could get down with that.
Naturally lots of characters don those colors throughout the course of the series, and Arc System Works has shown that they don't mind using the dregs of the Dragon Ball society for DLC, so it could be anyone. For now, it's fun to speculate.
