I was wondering if this villain might be a CM, so I decided to make this proposal to find out.
Multiversal Champions is a sequel series to Champions of the Multiverse, which is the main storyline of the Multiversal Legends universe. Taking place a few years after the last series, Jack Spark now has a son and now is the new leader of the Champions. The heroes invistigate a series of murders run by a mad cultist named Mavros. But it turns out Mavros is working for another dark entity....
Malsumis, who's real name is Miles Drekken, was an egotistical director of the Ascension Program hired by Nekrozoth himself as a means to make him into a god. He is Daevas's true archenemy and was the main antagonist of Multiversal Champions until Xorin returns and took the title as one. He made several cameo appearances in Champions Of The Multiverse, and finally makes his debut in the Multiversal Champions series.
He orders the kidnapping of several innocent people for him to condone his cruel experiments on, which resulted in the person being driven insane beyond recovery. None have ever survived the experiment, living piles of corpses left in the incinerators. One of his victims happens to be Daevas, whom he brutally experimented on, which leads to Daveas suffering from amnesia and forgetting about his past. After numerous people were killed in the experiment, Daevas became the first one to survive and become a demigod which leads Miles to do the experiment on himself to make himself a god. Upon success, Miles renames himself to Malsumis and attempts to make all living beings worship him and tries to kill Daevas as an attempt to steal his powers. Though he failed to do so, Malsumis partake in Nekrozoth’s war against creation as a means to further his own ambitions. After the destruction of the Old Omniverse, Malsumis made a deal with Xorin and became the Incarnation of Madness and a psychic being of malice and cruelty. Malsumis would torture people mentally until he either drives them to suicide or receive a permanent agonizing brain damage. He would even use the people he drove to insanity as his slave for his own nightmarish dimension and psychically feed on their suffering. Often forces others to partake in the most wicked desires he could imagine or invade their subconscious so he could twist their mind, making them aware that they are committing horrific deeds but making them enjoy it. He sees his psychic torture as a hobby to him, desiring to corrupt the hearts and mind every mortals he can and drive every single being to madness. Showing utter glee on his actions and even calling himself “The Coming Darkness” when tormenting his victim. When confronted by the Champion Jack Spark, Malsumis attempted to take his son and break his mind for his own amusement. Being behind the serial murders from Mavros, Malsumis used his followers to commit random acts of murder as his way of human sacrifices. One of the most heinous deeds Malsumis ever committed was his serial murders of several deities in an attempt to make himself the one and only god in the omniverse.
He was always a psychopath scientist, when he done the experiment on himself it did drove him insane, but he only went insane because he was mad with power and thought himself as a god. He has zero redeeming qualities or a tragic backstory that would excuse his actions. Also he didn't show remorse on the destruction of the Old Omniverse, since to him it was just a small accident. He only wants to bring it back because he didn't like the New Omniverse and wanted to rule the Old One as a despotic tyrant where he feeds on everyone's madness.
Though not as heinous to the likes of Nekrozoth, who is arguably the most heinous villain in the entire franchise. Malsumis comes close and is next to Vekkisul and Aka Manah as the second most evil beings in the omniverse. His attempted genocide on all other gods to be the only god in the Omniverse, and tortures people mentally until he either drives them to suicide or receive a permanent agonizing brain damage. He would even use the people he drove to insanity as his slave for his own nightmarish dimension and psychically feed on their suffering.
