History MadScientist / MarvelUniverse

* Characters/{{AIM}} (Advanced Idea Mechanics) is a terrorist organization of Mad Scientists, who wish to overthrow the world's governments and institute a technocracy.

* ''ComicBook/TheIncredibleHulk'': Bruce Banner usually isn’t this, but without the Hulk as an outlet, he can start to lose it as all his anger and darker impulses build up.

%%* Bruce Banner usually isn’t this, but lately it’s been shown that, without [[ComicBook/TheIncredibleHulk the Hulk]] as an outlet, he can start to lose it as all his anger and darker impulses build up.

** The Enclave is a similar group. Their most successful (or unsuccessful, depending on how you look at it) experiment created the being who would eventually become [[ComicBook/{{Warlock}} Adam Warlock]] (who very quickly turned against them).

* One of the villains of ''ComicBook/MsMarvel2014'', is a [[spoiler: clone of Thomas Edison with the head of a bird]] called The Inventor. In his own words, although not the kind "that's actually an idiot."

* Doctor Doom is an interesting case, as he is both a MadScientist ''and'' an EvilSorcerer. [[SorcerousOverlord As well as the leader]] [[EmperorScientist of a country]].
%%* ComicBook/SpiderMan's ArchEnemy, ComicBook/DoctorOctopus.

* The Mandarin is a Mad Scientist enemy of ComicBook/IronMan. He spends his time inventing mind-controlling super-cancers that run around like a cross between the Blob and the Borg. Or inventing orbiting Hate Rays to destroy the world with madness.
* In the Franchise/MarvelUniverse, AIM (Advanced Idea Mechanics) are a terrorist organization of Mad Scientists, who wish to overthrow the world's governments and institute a technocracy.

* Hank Pym (a.k.a. ComicBook/AntMan a.k.a. Giant-Man a.k.a. Goliath a.k.a. Yellowjacket a.k.a. The Wasp). Just take for example his origin story:

'''Panel of Scientists:''' Oh... what's that?\\
'''Hank Pym:''' I won't tell you yet! You would only laugh at me as you've done before! But when I've finished it, I'll show you! Then you shall know I'm a greater scientist than ''any'' of you!
** His long-lost daughter [[ComicBook/TheUnstoppableWasp Nadia van Dyne]] takes after him in terms of both brilliance (creating a pocket dimension lab at an age where pink crystal castles are the obvious go-to aesthetic) and obsessive tendencies (not having anything resembling a day[=/=]night cycle in said lab because anything indicating the passage of time is too distracting).
* The High Evolutionary basically lives inside a HeelFaceRevolvingDoor. On a bad day, he's the quintessential EvilutionaryBiologist, but even at his most benevolent, he's still got a towering [[AGodAmI god complex.]] His feats ''are'' danged impressive. Apart from creating his own race of [[UpliftedAnimal uplifted animals]] called the New Men, he also built his own '''''planet'''''!
* ComicBook/{{Blade}}'s arch-enemy Deacon Frost was an amoral scientist that performed experiments to gain immortality and upon and injecting himself with vampire blood, he becomes an unusual type of vampire with bizarre powers. He continued to perform his experiments such as producing clones of his victims (one of the special powers he gained) all so he could usurp Dracula's position as Lord of the Vampires.
* Dr. Rot from the ''Insane in the Brain'' storyline of the ''ComicBook/{{Wolverine}}'' comic, a lunatic running an asylum, whose particular flavour of insane science is psychic machines made out of human brains. Adequately summed up by the following quote, while he flees Wolvie with a fresh brain in one hand and a handful of cables in the other:
-->"We Rottenwells, like to make our own way, yes we do. And all I need to make mine now is [[NoodleImplements a paper clip, a cheese grater, a nine volt battery, a still-beating hummingbird heart, and the exhaust fan from a 1979 Chrysler LeBaron]]. Make way boys! Medical science is on the march here!"

* ''ComicBook/TheAwesomeSlapstick'' has Dr. Denton, Destroyer of Worlds, a five-year-old genius who built a giant robotic teddy bear.
%%* ''ComicBook/{{Runaways}}'': Chase's parents, Victor and Janet Stein, are a pair of these.
* The Weapon X project in its entirety is built on the backs of mad scientists, experimenting on mutants to create powerful and deadly weapons.
** Its civilian offshoot, the Facility, carries on the practice. Dr. Sarah Kinney's proposal to ''clone'' Wolverine, when mainstream science had only ''just'' begun having success with sheep and cats, is initially considered outright absurd by Zander Rice (though it owed as much to Rice's hatred of Wolverine for killing his father). Kinney outright equates cloning a mutant with [[AGodAmI godhood]].
* The Mad Thinker is both a mad probability expert, who can predict individual human behavior to a preposterous degree, and a [[RobotMaster robot master]] who constantly builds new robots and androids to sic on his enemies.
