I'm not sure if this would be a major villain for a finale. I believe he is Lena's enemy and not a threat to the McDucks. Good but not for the finale. Although I would have liked it to look like a ducky red chaos demon. I find him too much... and to have waste... well, it's not even a Marvel movie but a simple Ducktales.

Then again it wouldn't be so nice to F.O.W.L. to be good.

I found the best villain for the finale just now: A supernatural Solego (Chaos God)! Solego in 2017 super. I know he's kind of made cameo appearances but being a main villain would be perfect! With Solego's technology as armor to open pils in other dimensions (maybe someone like Miguel O'Hara).

I do have a think of a main antagonist for Season 4, but I have a series with a friend making it, and the "series" is a fanfic, so I wouldn't say it right now or spoil the fun out of my series/continuation after Season 3.

Perfect! Can you give additional information about the name of the series, the powers of evil and also about his name?

I don't really like to spoil it.

If it were to be a single villain, probably Merlock. They’d have to find a way to make him stand out from Magica though. Scrooge mentions beating El Capitan in The First Adventure, so I don’t see him returning as a big bad. Shere Khan has some definite potential, but it’s hard to imagine one billionaire being able to take on Scrooge and all his assorted allies without help. As for Negaduck and Steelbeak, I feel like it’s better for them to be Darkwing’s adversaries moving forward, and not drawing Scrooge in. Maybe the nephews could get involved, and of course Launchpad and/or Gizmoduck, but Darkwing’s adventures should mostly be separate.

Solego might have been an interesting option, but his reimagining as a “mad thinker” makes it seem unlikely. Plus, even if he were still a “chaos god”, I don’t really see what would set him apart from the likes of Magica.

Read the comic story. Solego is top notch, nothing to do with Magica. In a fight I'm sure Solego would win!

As for the rest, I think actually seeing FOWL again would be boring, but I'd keep Negaduck (for the DW Reboot) and Merlock (for a possible movie). El Capitan could appear as could Merlock (where he was also mentioned) but his story has also been repeated twice (The Treasure of the Found Lamp and Quack Pack). Shere Khan really wouldn't be able to take on all of them together but who knows, maybe Ducktales would make a stronger version (I'm a big fan of TaleSpin so I'm voting this in DT2017).

I meant that Solego would have to be given abilities or traits that would set him apart. There needs to be a reason to have Solego in addition to having Magica, as opposed to having him do something that Magica could be doing. It’s like how the creators rejected Merlock because they already had Magica.

You have right.
