So do you think Adam is the main antagonist of the series as a whole? Sera and Roo would be the Antagonists Overachings

Probably not

Then maybe Lute is. Vox I think will be the Secondary Antagonist of the franchise in general

Personaly think Roo would count as Overaching Antagonist instead of main antagonist

I agree, she and Sera would be the Overaching Antagonists. Although Sera will most likely be redeemed. The Main Antagonist could be Lute or Vox. But I feel that Vox will be more of a secondary antagonist.

Lute

I think this will be a case of "X is one of the main antagonists of...". Like, we have more than a single main antagonist. And from the looks of it, Lute will definitely be one of them (Vox is coming pretty close too).

Bruh, I voted Adam accidentally, I meant to vote Lute

Well, I was hesitant about including Adam since he's dead, so I think he'll stay as an Antagonist Major. Lute is most likely one of the main antagonists. Vox may be the other main antagonist or the secondary antagonist alongside Valentino and Velvette

Valentino maybe; Velvette will problaby just stay under "major". Also, I think we are underestimating Lilith here, she has potential to become one of the big villains.
