Catnap isn't on that list.
There is something to be said for a good villain: The hero of their own story. For Doc and Celine, that's definitely the case. For Deception? Much less clear.
Fellback? I can't really say I know his story. Heck, just trying to track down his plotline across the whole story is ... probably impossible. And his motives and goals? Why toss the whole bottle of WCA at Jenny given both how hard it was to get (how did he get it, anyways?) and the need of the EO's for it. Catnap was trackable, but he's go that little hiatus just before PSI that made it hard. I can at least follow his motivations, drives, etc. He's definitely trying to show the rest of the comic worlds what horrible creatures authors really are.
Editor? To be honest, I can't yet understand what his step 2 would be. Step 1: Take over the Webcomics. Step 2: ?
Why the first step in the first place?
Much as I like that Naga, I can't make him my favorite villain just for that.
"So my Mom left me a huge heap of molding, rotten, decaying, puss-dripping zombies ... How cool is that?"
"So what is your advice to me?"
"Stop doing stupid crap."
