Cell Games!

Mewtwo is great, but I don't think he can stand toe to toe with cell. Mega Mewtwo Y definitely would do it more traditionally, but I don't know...Pokemon? And Arceus can still be bounded by mankind by being caught. Cell is a creation of man, sure, but he has the collective strength of beings that are unknown in power, and has far exceeded and evolved past what mankind can truly understand in unadulterated power.

Cell was the greatest villain because he was hamming it up the entire way through.

Everyone else was either too tryhard, too serious, or bubble gum.

He is fined for mass transmission without a permit, and is arrested if he refuses to pay.

How powerful are these gods? Cell can beat the gods of some fictional settings.

Even then, Cell isn't one of Arcus's creations to begin with, since he's from DBZ land. He might not be able to unmake him

The Nations of Khorvaire are in an uproar. The dragonmarked houses and the nobility can't come to an agreement with each other or themselves, and the less controllable nations begin to take drastic measures.

The dragons of Argonnessen, while worried about this creature's ability to hijack their magical communications, are largely ambivalent towards the situation unless he demonstrates he's an actual threat to them, or the Prophecy wills it.

The Inspired of Sarlona send out propaganda to their subjects that all is well and to disregard that strange transmission. Meanwhile, the quori freak the fuck out as they desperately try to figure out how this infiltration into their dream/mind-control network happened.

He's a fucking amazing villian in the abridged series

>One on one combat
Oh please. Gohan had a ridiculous amount of help fighting him.

Well the Cell Games started off as "One on One combat" as per the rules.

SSJ2 Gohan was literally toying with cell before he came back with a Zenkai boost. He probably could've destroyed Cell right there if he was thinking straight.
