Doctor Chaos
Doctor Paul Chaos comes from a long line of supervillains.
There was the original Baron Chaos who ran the Circus of Crime during the 1930s.
There was General Chaos who ran an Anti-Communist/Anti-Capitalist military outfit during the 1960s.
There was his mother, Professor Chaos, who worked with the Anti-Reaganite movement as a sort of outdated Flower Child villain.
Hell, his sister became Major Chaos of the "Stripper Ninja" 90s villainess set. THAT was awkward for family reunions, I can tell you.
Paul was determined to avoid his family's destiny and devoted himself to trying to bring attention to the various causes which lead to supervillainy. He wrote several papers on the subject and a number of extremely insightful books while studying to be a psychologist.
Later, he studied medicine with hopes of specializing in Changeling superpower-related conditions and made preparations for a massive project on how several of these related to supervillainy.
Of course, no one in the world would publish Paul's work and he was considered something of a national joke after his university revoked his degree over nonexistent irregularities. In the end, Doctor Chaos had to leave the United States for Atlantis where he was informed he would be allowed to continue his work. Joining a think-tank of other geniuses, their research formed the basis for the Riese-Diederich Syndrome diagnosis. Doctor Chaos admits he didn't do all of the work but he believes himself to be responsible for at least 40% of the major breakthroughs the team made. To this day, he refers to it as Riese-Diederich-Chaos Syndrome.
Unfortunately, many of his fellow psychologists felt Doctor Chaos was a walking public relations disaster. As a result Doctor Chaos was deported due to suspicions of working with a Nazi offshoot of Eclipse (and some tips to that effect from reputable sources). It should be noted that in addition to being of Russian descent, the Chaos family is Jewish. Let's just say Doctor Chaos felt his treatment in Atlantis was below the belt.
Undaunted, Doctor Chaos changed his name back to its original pre-immigration one (Chouraqui) and began illegally working as a pediatrician in South Dakota. Against his will but not against his ethics, supervillains around the country somehow tracked him down and came to him for medical treatment. He became notable, during this time, for his work with changeling children and using a false name to continue his research into superpowers and their effect on psychology.
That was when he met Nightingale, a Changeling supervillainess who didn't seem so much a sociopath as vaguely unethical. The two began a relationship as Paul started counseling numerous supervillains about the problems in their life, believing that he could help turn their lives around. Surprisingly, it seemed to work and almost a dozen of them began to show serious progress towards normality.
That was when the SHIELD-equivalent launched a drone attack on his office, killing thirteen people (including eight children). Nightingale was seemingly killed in the blast and Doctor Chaos was painted as a mass murderer conducting experiments on the local populace's children by a VERY embarrassed State Department.
Doctor Chaos' response? "That's it, screw it. I'm a supervillain."
Contacting the surprisingly large number of supervillains that had become emotionally dependent on his psychotherapy and/or who believed him to be some sort of genetic evil mastermind, Doctor Chaos formed the House of Villains. He promptly set about his ultimate plan to get revenge on a world that had hideously wronged them. By exposing the hypocrisy of all their efforts and making the world a much better place.
He's had mixed results.
Appearance: Doctor Chaos wears a long red cloak with a hood up, which makes him vaguely look like a Sith Lord. He deliberately blackens out his face for most communications and alters his voice when dealing with people outside of his group. This is for a very good reason. Frankly, he looks a bit like Neil Patrick Harris and isn't exactly the kind of guy who inspires terror in the hearts of his enemies.
Personality: Doctor Chaos is a surprisingly congenial evil mastermind, being extremely genre savvy and capable of putting on the attitude of a supervillain despite being about as far removed from it normally as humanly possible. As GO-TO says, you'd be surprised at how effective the media depiction of an evil mastermind is in real-life crime. One oddball quality is despite being a trained psychologist and medical Doctor, Doctor Chaos is a geek who inserts more pop-culture references in his regular speech than any normal person should. This is his way of dealing with stress and the more he makes, the more crazy a situation has gotten. In short, he's John Crichton pretending to be Doctor Doom.
Truth be told, Paul's "Becoming the Mask" as his original plan of proving he was a good person by being a supervillain "done right" is unraveling due to the number of horrors he's witnessed. After seeing the handiwork of a few of the monsters he's taken his team against, he's had no objections to simply having the bastards gruesomely killed. As a result, Doctor Chaos has a lot of blood on his hands. He's surprisingly okay with it.
Powers: Doctor Chaos' cloak is a heavily reinforced piece of alien cloth immune to virtually all energy weapons and possessing a kinetic dampening field that means he can survive being beaten within an inch of his life.
Likewise, he has his "Chaos Gun" which (frankly) does whatever its going to do without any real input from Doctor Chaos. The weapon is powered by a piece of the Expanse in physical form. All the Doctor knows is that 80% of the time it'll do something useful to him and the remaining 20% of the time it'll do something stupid like a Wand of Wonder. So far, it hasn't backfired on him.
So far.
Doctor Chaos also has a number of weird vehicles including a converted alien spaceship, a stolen prototype superplane, and a car from the 30th century he uses in his heists for getaways. He keeps them in an Indonesian Island Lair that can link up between, I shit you not, a stolen one-way rainbow bridge from Asgard. He inherited the majority of this stuff and the rest, obviously, he stole.
