I never considered Amity a villain either.

I am glad you guys you felt this way. Really shows that even the audience saw the good in her even when she was initially negative. Even if she wasn’t really a villain, I still feel that her redemption storyline was one of the best written for an antagonistic character.

It’s fine, I just felt the need to specify.

@AdmiralZod1 Yeah, her character development was really good. From the hero’s rival to her girlfriend, even this alone show us how much she grow as a person.

Lord Viren, Isaac, Hordak, and Adachi.

Kylo Ren

Zuko

Vegeta, Vader and Zuko. I love the Collector’s too

Doctor Octopus comes to mind

Excluding the above examples, I also really liked Vandal Savage's redemption arc in the Justice League cartoon. After committing mass murder and attempted world domination for countless millennia, he spent 30,000 years in complete isolation after wiping out all life on Earth via gravity imbalance, regretting his actions while unable to fix his mistakes because he can't go back in time to any period where he still exists. Then Superman was accidentally sent to Savage's time by Toyman, and since the former was already "dead", he was thankfully able to fix the past. Savage's last words before fading out of existence forever are "thank you, my friend."
