That's what I was wondering who could be the ultimate bad guy of the whole Superki, and after some lengthy deliberation I decided that the ultimate antagonist to end the DBS series would be Frizer. Because he probably has the most far-reaching plans of the villains so far, as we know from the anime his ambition is to overthrow Zeno, and it would only be on a dream that this ambition would end because Zeno can remove him before he lifts a finger. There was also this guy Hearts but he was not able to defeat Gogeta, let alone overthrow Zeno. Frizer himself hasn't appeared since Broly, it's been three arc's (Moro,Granolah, Super Hero) and he's only been mentioned in them. As if they were preparing him for something bigger, and it would be a nod to fan rumors and theories that Toriyama was going to end Dragon Ball on the Namek saga where the ultimate bad guy was Frizer.
