I’ve always love Hopper from a bug’s life
Scar as well especially if they added the deleted scene then he would’ve been in my eyes perfect (but as he did in the life action but then te animated one).
Both because of the amazing written villain speech
Welp imo, a good villain, opposes the hero of the story and has their own motivations that make them believe that they are their own hero of the story. They have redeemable qualities and strengths that make them a significant adversary to your hero. They shouldn’t be too weak so that the hero can easily defeat them nor should they be too powerful so that they could be portrayed as a villainous “god”.
A villain should also be compelling and captivating enough for the audience to root for them. Let’s be honest, no one would support a two-dimensional villain (such as, I’d probably get murdered for thisKarli Morgenthau from TFATWS or, even worse, Euron Greyjoy from Game of Thrones).
For instance, let’s look at Thanos (MCU version). He was a villain and he believed solemnly that it was his destiny to wipe out half the population of the universe by collecting all the Infinity Stones. It became his sole objective. His mission wasn’t to fight or oppose the Avengers but fulfill his “destiny”. The depth of personality also captivated the audience for which they couldn’t help but criticize as well as respect him. Same goes for Tywin Lannister from GoT.
