Doctor Ivo Robotnik

Doctor Ivo "Eggman" Robotnik is not originally from this universe. Instead, he came from an alternate universe located in a plane of reality X'habhumaphu has less power over.

Description
Robotnik came to Zobooland after his creation Roboomafoo discovered it, only to go on a killing spree stopped by that universe's Slimantha after catching a glimpse of X'habhumaphu and going mad. Now trapped in Zobooland, Robotnik has dedicated his life to hermitude to avoid the dangerous residents of Zobooland, much like Noggendrill. Robotnik is has also altered his own DNA to help him survive the harsh conditions of this new world. Robotnik is the creator of Narchi in the alternate universe, somehow creating him in this plane of reality as well due to his playing God; it is possible that X'habhumaphu came to him in a dream and instructed him to construct Narchi, but as Robotnik is X'habhumaphu's adversary this may not be the case. He is immune to Green Puppy, as if Robotnik has any scent, it's a weak metallic one, and his buttcheeks are too tight anyway. Slimantha. on the other hand, could potentially destroy his internal organs or robotics due to her polymorphism. One time, Robotnik even had an encounter with her, however, due to his robotic parts giving him increased fighting capabilities, he was able to defend himself and get away. He is currently studying how to get rid of Slimantha (One attempt being Bombendrill) and Green Puppy, but no longer cares about killing Narchi.

Abilities
While there is no differences from the outside, Robotnik has accelerated regeneration (can repair a limb in a couple of minutes.) He can also adapt to environments and situations over the course of an hour.) He even has the strange ability to generate metal as a biological material. This is seen when Samantha rips out some of his intestines, only to have robotic arms come out, grab the organs, and put them back inside correctly. The wound then repaired itself, and the arms were deconstructed. Due to how his regeneration works, he can technically never be killed (I.E. turning back to normal from a pile of ashes.) This is because his body doesn't need the things normally required to sustain life, such as creating its own energy without an energy source such as the sun, not needing water or food (Though still eats.) He can also polymorph weapons, just as a gatling gun, rocket launcher, and even a laser that could possibly melt Slimantha (though further research is required to prove this. She would probably just regenerate anyway.)

Beliefs
Robotnik, like Noggendrill, is only K'hrattist in the sense that he's against X'habhumaphu. He doesn't believe anything about Judgement Day, he only hopes that it never happens. Unlike other K'hrattists, Robotnik also believes that everyone, from foes to worshippers of X'habhumaphu, will be destroyed, even the immortal beings such as Slimantha and himself.

Robotnik believes that the reason that Judgement Day hasn't happened yet is because X'habhumaphu is growing in power, and is waiting for the moment when he can finally strike. Because of this, Robotnik believes that it's better to destroy X'habhumaphu sooner, rather than later.

X'habhumaphu
As an enemy of X'habhumaphu, Robotnik has spent most of his time experimenting and thinking of ways to defeat X'habhumaphu. This is incredibly dangerous, as X'habhumaphu could very well be the thing that brings an end to Robotnik's immortal life. Considering that Robotnik has created an inter-dimensional portal in the past, if anyone's going to reach X'habhumaphu, it's going to be him. Defeating X'habhumaphu is a completely different story, however. Just to stand a chance, Robotnik may have to further his bodily alterations far beyond the point of even Slimantha. Most of all, however, Robotnik will need help from far more people than just Noggendrill.

Noggendrill
Robotnik and Noggendrill combine their knowledge to think of ways to destroy X'habhumaphu. Robotnik has also tried to give Noggendrill the same alterations that he has, though all of these have failed. Because of this, Robotnik's immortality may have nothing to do with his alterations. They both eventually came up with the theory that Robotnik is just naturally immortal, and that he has the ability to curse machines with a sort of "lesser immortality". This theory is supported by the fact that Robotnik has had the alterations for as long as he could remember, but he didn't figure out that he had them until he came to Zobooland. Robotnik can also revive Noggendrill inside his lab, should he ever die. Apparently, Noggendrill's body or even a part of it is not required for his revival.

Slimantha
Robotnik and Slimantha are in many ways similar. You could say "A polymorphic being who is immortal and doesn't need food or water" and be truthfully referring to either of them, though most people would think you are referring to Slimantha. Despite their similarities, Slimantha is still more powerful. Regardless, a battle between them would never end with either of them dying, as both are immortal, as both could regenerate from any kind of damage.

Green Puppy
Robotnik is notably immune to Green Puppy. Robotnik, for whatever reason, doesn't seem to have any smell even reminiscent of any kind of biological matter (assuming he even has any), and instead has an incredibly weak metallic smell, assuming he even has a smell. Furthermore, Robotnik's buttcheeks are too tight due to his fatness. Hypothetically speaking, if Robotnik got a smear of feces on his somehow, and Green Puppy reached him before his body could automatically clean itself, and Green Puppy's penis got past his buttcheeks, Robotnik would probably just use his abilities to create a punch of sharp metallic objects to mutilate Green Puppy's penis.
