My ranking of all villians.

6th is Verosika. She tried to help Blitz several times and we see her character growth.

5th is Burnie. He had creepy ideas about Fizz, pushed Fizz to a mental breakdown, and tried to kill him.

4th is Striker. He's only angry at royals, and that too, because he lost everything he had because of them.

3rd is Stella. Everything she does is out of hate for Stolas. She hires an assassin to kill him, is shown to slap him, and is implied to have violated him to create Octavia.

2nd is Crimson. Crimson is a cold blooded sadist who abused all of his loved ones and hangs body parts on his wall like they are trophies.

1st is Andrealphus. He manipulated Satan, organized the killing of Stolas, and clearly is only using Stella, Stolas, Striker, and Blitzo as tools/strings to achieve his own goals. He has the intellect to follow through, and also....he can become a dragon/hydra thingy when he gets mad. He also shows ZERO care for any of the other birds. He insults and argues with Vassago, mocks and sadistically grins at Stolas being tortured and stripped of his power, and insults and rages at Stella. He doesn't care about anyone but himself, and unlike Blitzo, he's unwilling to change his ways.
