The other part of my villain height comparison that had to split because of this site's file limitations. Anyway here's Kirvak, ??? and Zalfzed.
As a summary on each as a character:
-Kirvak a fascist that believes their alien species known as Vishquinza is the superior one. She isn't very nice about it. The fact she actually has a fleet of ships and thousands working for her is not a good thing.
-??? is... we're not quite sure. They tend to hang out with Zalfzed and they're a bit of a wind bag but otherwise their motivations aren't well known. Even their species isn't actually known.
-Zalfzed is literally the worst person imaginable. He goes through life much in the same way most 11 year old children play GTA. He literally does not care about any social taboos which makes him sound cool until you realize what kind of shit people often frown upon in this world. The fact of all the villains he has the most overall influence is pretty scary.

So enjoy!
