Complete Monster/Edens Zero

File:Illega.png
The Darker and Edgier *Edens Zero*, in contrast with the predecessor *Fairy Tail*, has made itself the task to make most of the villains as despicable as possible and some of them take it even further.

* Illega is a bloated frog alien who pays criminals to kidnap and bring him women, who he turns into stone statues to be used as furniture. Once Rebecca uncovers his room containing hundreds of stone women, Illega arrives holding Copa at gunpoint, promising to release her should Rebecca kneel before him and become his toy forever. When news of the planet destroying Chronophage arrives, Illega plans to start his collection again on another planet.
* Spider goes by the name Jamilov in the digitized world of Digitalis. Cheating to give himself an advantage, Jamilov wanders through the fantasy computer world, slaughtering the living NPCs for fun, while taking a special joy in murdering player characters so he can also kill them in the real world, exterminating entire towns. When he arrives at the town Shiki and Rebecca are at, Jamilov tortures and impales several PCs upon a spike to let them die slow and gleefully brings an army to massacre every living thing there, even trying to murder a child for an advantage. When thwarted, he tries to erase the Eden's Zero and kill everyone aboard the ship for sheer spite.
* Dr. Müller was initially presented as a kind scientist from Planet Newton who aids an android named Hermit to complete a contraption known as the "Accelerator" under the pretense on saving Hook, a neighboring planet filled with androids. In truth, Müller manipulated Hermit to build a superweapon to obliterate Planet Hook, and after said planet is obliterated, Müller reveals his true colors by saying that humans are superior to machines, before beginning to torture and dismantle Hermit for research and for his own amusement.
* Kurenai Kogetsu, aka Madame Kurenai, was a slave freed by the heroine Valkyrie. Rather than return to her lost daughter Homura, Kurenai married the slaver Baron Mordo and murdered him to take over the planet Sun Jewel. Running the world as a horrific tyrant, Kurenai uses an orbital cannon to vaporize anyone who defies her and amuses herself via sadistic games such as burning a model's face off and using him as a broken pet. Upon the rebellion of the mining districts, Kurenai decides to exterminate them all, including her own daughter, simply to show she is not to be defied and to punish them for still honoring Valkyrie's memory.
* Drakken Joe, the first member of the Oracion Seis Galactica, as well as the first Overarching Villain, is greed in human form. Once a child of a planet, where people were bio-engineered to life for only 15 years, Drakken couldn't accept this fate and decided to prolong his lifespan to make friends. But rather than keeping on with seeking friends, Drakken became obsessed with his immortality, instead. He later turned Guilst into a criminal planet full of criminals and cut off Weisz' arm for stealing his money. In the present, he keeps himself young by absorbing the lifespans of other people. He did it already on two planets and does it still again. In his first scene, he tortures one of his debtors by forcing the man to hold a heavy bottle with his mouth and then breaks the man's jaw with his foot. Fast forward to his arc, where he has Labilia tortured for insulting Rebecca as an attempt to impress her, not understanding at all that Rebecca is horrified about this. After he and his group defeat Shiki's gang, he once again cut off Weisz' arm (who was restored to his younger self prior via Chronophage who ate 50 years off their planet, but left the other planets be) as well as destroying Weisz' medicine, laughing about it with his likewise sadistic enforcers and shoots Shiki in the head to activate the key in Rebecca. Only thanks to Rebecca's time-leaper-skills could the damage on Shiki and Weisz be restored. It was also revealed, he had stolen Madame Kurenai's laser to blow up Blue Garden just to kill his partner-in-crime Master Noah, who likewise wants to get rid off him. A sociopath, who kills anyone around him without needing to shoot them despite his own no-killing-rule, Drakken is one of the most wanted criminals for good reason.
