If you could cast any MLP villain as a Disney villain, who would you choose and why?

Tirek or Sombra as Scar
Chrysalis as Ursula
Sombra or Tirek as Jafar

7508663
Nightmare Moon as Scar, considering they're both royals that were jealous of their siblings and have tried (and, in Scar's case, succeeded) to kill them.

7508663
Pony of Shadows as either Chernabog or Maleficent.

7508663
Sombra as Scar.
Discord as Hades, a fan favorite who is a god and also has a deal maker mindset. Also the pop cultre refrences.

Didn’t Sombra reference Scar at one point?

Not sure if it's a reference, but he does say Scar's famous line.

I once did a PMV with this question in mind, there the cast list was.

The Evil Queen: Nightmare Moon
Maleficent: Queen Chrysalis
The Queen of Hearts: Cozy Glow
Mother Gothel: Adagio Dazzle
Jafar: Lord Tirek
Lady Tremaine: Principal Abacus Cinch
Cruella De Vil: The Mane-iac
Captain Hook: The Storm King
Doctor Facilier: Discord

However, I will admit, I choose some more for how they worked in the song rather than just in general.

In fairness it really does work for the most part. I'm not sure about Cozy Glow as Queen of Hearts though.

I'm not sure about Cozy Glow as Queen of Hearts though.

Who would you pick in that role?

Maybe Suri?
