About Villain!Professor Membrane:
-He’s a secret Irken, and neither of his kids know this because he’s always stayed in disguise. While on Irk, he was a scientist that worked on keeping the control brains functioning and also worked to re-encode PAKs. He started getting a power trip as he felt the lives of Irkens in his hands, and secretly began experimenting on those that were sent to him. This power craving only grew when Almighty Tallest Spork was killed, and being that he was taller than his fellow Irkens, he was sent to get a height enhancement and become the next Tallest. Yet as he worked on Control Brains, he knew that they would only keep him in check. He wanted real power, not to be a drone of those things. So, after the injection grew him to a good 6′4′’, before his PAK could be re-encoded into Tallest, he fled from the coding planet and began to look for a far, far distant place where he could control an empire to his own liking. This brought him to Urth, where he lived in Mexico for a good few years and took on the disguise of a human scientist. He worked on cutting off all communication to Irken tracking, and since he was so far away he was able to go completely off grid after only a few urth years. Paranoid that he’d still be found, however, he moved to a small city in America that hid him well.
-After years of making his way to the top, both by eliminating his rivals and proving his intelligence, Membrane became a well known scientist who’s goals seemed pure: that of world peace. Of course, his real goal, is complete control of the planet. Which should be easy due to the idiots that inhabited the planet. However, he found that due to the faster gravitational pull, he was aging faster than he would on Irk. He needed to slow down the process, and began experimenting on himself to do so. Making his body more mechanical, with cybernetic limbs, he thought it would do the trick. It didn’t, and he had one other choice. A clone. Yet without the access to Irken systems, he couldn’t simply put his PAK on a new body. He had to create something entirely new.
-Dib was the first success in a line of human and Irken hybrid engineering. The only way he was able to get his experiment to work, was by copying the human aging system from the start. Ironic how that damn aging problem was still going strong. But he was sure that his work would carry on in this boy.
-Membrane, at first, was an excellent parent. He cared about Dib more than anything, and like any Irken, the child was already a genius when he was young. Except... he was a little too into his Irken lineage, instead of the science that Membrane was trying to teach him. After a tough decision, the man wiped his young son’s memory of anything Irken, and tried anew. Yet the boy still only wanted to focus on space, and aliens. No matter what he did, he couldn’t get Dib to stop obsessing over them. It was a good thing he also had Gaz.
-Gaz was his second successful attempt, but with her he put more humanity into creating her. She would be free to choose her own path, and he would watch what she chose with fascination. She soon became his favorite after Dib grew without following the path he chose. Yet after a conversation with Gaz about what she wanted to be in the future, she also said her disdain at being a scientist.
-When he found out his two clones wouldn’t carry on the legacy, Membrane stopped being a good parent. He began obsessing over making sure that his legacy would carry on, and Dib especially became subject to that hunger for control. While he used to give the boy what he wished in hopes of growing out of it, like buying him different paraphernalia of supernatural beings, he became harsher and strict when he was home, insisting that Dib follow the path of real science. When this didn’t work, he began to ignore and ridicule the interest in the paranormal, even when he knew most of what Dib found was real in hopes that the constant disparaging would bring down the boy’s hopes of being a paranormal investigator. It almost did, and he was more than fine with Dib’s focus shifting more towards space. Astrology was fine. But then... Zim came along.
-It was obvious to Membrane that Zim was an Irken, and at first he thought that the Irken child was there for him before it was apparent he was made an invader. Irk really must be falling apart without Miyuki there, and he wondered who became the new Tallests. Because whoever they were sent an absolute idiot. But of course, Dib would see right through the pitiful disguise and ignite his desire for paranormal studies even more.
-As the years went on, Membrane became more neglectful and downright mentally abusive to Dib, who on many cases died in his foolish attempts to “stop Zim”. Membrane had to continuously replace him with copies and infuse his memories, hoping that one of them wouldn’t be a failure. Yet each time, Dib would get up, wipe at his eyes, then declare his mission to fight the Irkens. It frustrated him to no ends, to the point where he began to send him to institutions to try to rid him of the nonsense.
-Meanwhile, he hoped that perhaps if Dib kept being a failure, Gaz would take on the legacy. He was much kinder to her, although plenty neglectful and manipulating. He figured different tactics might work with his other child, but she was far too withdrawn for him to tell if it was working.
-He experiments on his kids , himself, and whoever he gets his hands on all the time. Gaz developed powers from a particular experiment.
-There’s a lot of manipulating with him, especially with Dib. Dib is only praised and paid attention to when he’s following the path that Membrane wants him to.
-He puts on a facade of having a perfect family for the rest of the world, because he doesn’t need his experiments taken away from him.
