Villain Exchange Program

With all the discussion of villain effectiveness in season 3, IDW villain upgrades, and a general desire to revive some of the bigger badasses of Gens 1 and 2, I’m curious what villains from other shows you’d like to see ponified and put into the series. In addition, discuss what direction of lightheartedness or grimdark you would expect from this change.

No grim dark. Or at least subtle grim dark.
 
But Smoooooze

Dudes, hear me out. What if they took Q, from star trek and turned him into a villain in MLP. Like a demi-god who can manipulate the fabric of reality.

@Torpy Pony
I’m not that big of a Trek fan but Q was more of a jerk and a bully than an outright villain.

Besides we already have Discord don’t we?

@neutralgrey
That was the joke, it’s the same person. lol.

Seriously, but what if Doctor Robotnik from the Early Archie “Sonic the hedgehog” Comics was wrecking havoc in Equestria. He was pretty brutal to his subjects.
