Tighten and Yokai.

Tighten by far. Great twist villain even though the space dad thing was a bit childish. Yokai just spends all these years without planning revenge against Krei but the moment he sees Hiro's micro bots we gets provoked into revenge.

Dawn Bellwether and the Kingpin.

Scar and Frollo.

Kingpin. Bellwether was another failed Disney twist villain although maybe overhated.

Haven't seen Frollo's movie.

Prince Hans and Rex Dangervest.

I need to rewatch Frozen. I haven't watched it between a long time and forever but I will still probably go with Rex Dangervest.

The Fairy Godmother and Dr. Facilier.

Adam or Vox
