Radiguet and Shadam Compared
If there are two villains worth comparing to are Radiguet and Shadam. So far Radiguet is considered by many as the most vile piece of scum ever. If anybody else had succeeded in being close (or maybe exceeded him), it was Shadam who some may consider is worse. And yes Shadam, I really wanted Daisuke Tachi to act out the character since the closest character to come close to Radiguet is... Shadam. Both of them started out as de-facto leaders of their group. Radiguet was the most powerful of the Vyram's elite. Shadam is the most powerful of the Gorma Triumvirate. In their case, neither of them wants to be ruled by another. Both are in my list of favorite villains.
Both of them faced opposition from a child villain. Radiguet had to deal with Tran (who later grew up to be Tranza). Shadam had to deal with his own son Akomaru who he does not care about at all. Obviously neither of them is ever child friendly. Tran mocks Radiguet while Akomaru mocks his father Shadam. I just thought in Shadam's case, you could feel more hatred for how he treats Akomaru. No matter how much of a dick Akomaru is, he is STILL Shadam's son! With that scene in mind, I really wanted Tran's actor to be Akomaru and Daisuke Tachi to be Shadam.
Both Ryou and Ryu didn't only clash with a character played by Takumi Hirose, both of them also clashed with the supreme bastard of the show. Radiguet hated Ryu the most and shared a powerful rivarly. Shadam also hated Ryou. Unlike Ryu, Ryou was able to settle his rivalry with Shadam out of suit killing the mad man in the process.
Both villains hated to be under somebody else' authority. Radiguet didn't want Juuza to return knowing he will be a servant. When Tranza became the de-facto emperor, he wanted to get rid of Tranza so he alone will rule everything. In Shadam's case he hated the fact his son Akomaru was above him, he hated having Tenpou around and he also hated Gorma XV, since Shadam wants to rule the world by himself. Shadam was more subtle about his hatred though compared to Radiguet's batshit insanity. Both of them overthrow their superiors and became the final villains of their shows.
After overthrowing their superiors, both went ridiculously powerful beyond imagination but at the same time, were losing their remaining sanity. So they got rid of their opposition, they are now literally the last man standing to face the heroes and are more than ready to fight the final battle. Radiguet goes crazier after overthrowing Tranza such as turning Maria into a monster, Shadam begins his short reign as well. Both suffered mental breakdown while they got more powerful. Both of them also suffered an utterly graphic death. Radiguet had a mouthful of blood, Shadam had a mouthful of mud.
