Marvel's female supervillains are as diverse as their male counterparts (but infinitely more fun). These villainesses have a lot of power, a ton of grit, and they stand down against their toughest adversaries like it's nothing, fighting a good fight with ease.
They are so good at being bad that you root for them, perhaps more than you should, and suddenly the antagonist becomes your hero. So, who are these villainesses? They're strong, they're tough, and they make a life of crime almost desirable.
10 Nightshade
Nightshade is an exceptionally smart villain who is a self-taught expert in biochemistry, genetics, robotics, cybernetics, and physics. She uses her skills to further her own interests and has worked as a criminal scientist and advanced her villainry over time. Nightshade has invented highly advanced weaponry and her body can release a scent that attracts and controls some animals (such as werewolves), allowing her to use them in a fight This criminal scientist is not one to be trifled with!
9 Bombshell
Bombshell is a juggling and explosives expert who uses various hand grenades and smoke bombs to overwhelm her opponent, and fireblasts in her wrist bands. Her skills are solid: alongside Oddball, Bombshell was successful in handing off Hawkeye and Mockingbird to Crossfire (a task that she and Oddball were hired to fulfill). Bombshell was instrumental in disarming and disabling Mockingbird and Hawkeye. And, even though Hawkeye escaped and defeated Bombshell, Oddball, and Crossfire, she overpowered Hawkeye initially, and that's no easy feat.
8 Black Mamba
Black Mamba, a member of the Serpent Society, is a popular antagonist who has been proven to be a mighty opponent against some of Marvel's finest heroes and heroines (including The Thing from Fantastic Four).
Black Mamba's supernatural abilities, which are believed to have come from a brain implant, include the power to read the minds of those around her. She can give people images in their minds that will confuse and disarm her opponent, and she can produce an energetic power cloud that allows her to pull in her victim and end them (and at that moment, her victim will believe it's someone they love beckoning them).
7 Mystique
Mystique is a shapeshifter with the ability to look like any breathing thing (human or animal). She can also change her voice to be that of the person she's taken on the appearance of.
Mystique also has the ability to create inanimate objects that connect with the person she appears to be (including clothing, guns, shoes, books, and glasses). Mystique never ages, as her cells are always mutating and retaining her youthful appearance when she's in her natural form.
6 Superia
Superia is a gifted criminal scientist with powers that she attained herself through genetic modifications. She has superhuman strength, can fly, and is skilled at hand-to-hand combat (which she's used when facing off against Ms. Marvel). The force of her punches is so powerful that she once bloodied Skaar's mouth with one blow. And with advanced healing powers, she can take multiple hits without being out of commission. Her fists produce green energy bursts that cause explosions (as she did when she escaped from The Avengers). And, on top of all that, she's a skilled martial artist.
5 Anaconda
Anaconda, a member of the Serpent Society (along with Black Mamba), is a villain with style. With her adamantium arms, she can crush and choke her opponents quickly. She lengthens her arms and legs for crushing and choking her victims, and when her arms and legs expand and lengthen, they swim with blood and look like massive snakes. A surgery gave her gills, and with that addition, she was given the ability to swim and breathe underwater. She's also skilled at streetfighter and has used her skills in that area when facing off against Captain America. She's tough and doesn't give an easy fight.
4 Lady Deathstrike
Lady Deathstrike is a mercenary and assassin and is best known as the archnemesis of Wolverine. Her father (Lord Dark Wind) formulated the adamantium-bonding method that was used on Wolverine by Weapon X. She has superhuman strength and endurance.
Her bones are unbreakable and adamantium metal is fused to her body. Her fingers were replaced with adamantium claws and they can cut through anything. She is seriously deadly and has given Wolverine a good fight on multiple occasions.
3 Hela
Hela, otherwise known as the Goddess of Death, is the ruler of Hel and Niflheim and the sister of Loki and her archnemesis of Thor. She has superhuman strength, speed, agility, and reflexes. She can withstand a great deal in a fight and she can release powerful bolts of energy that can age or kill her opponent.
Her fights against Thor have shown her might and ability. During Avengers's Prime, Thor faced off against Hela (following a fight with The Enchantress) and fails to overcome her. Her strengths are hard to beat.
2 Emma Frost
Emma Frost, also known as White Queen, is best known as the archenemy to the X-Men, for a time, before turning and becoming an important member of the X-Men. But before she was good she was bad, and that's why she's on this list. As a telepath, Emma Frost has the ability to share information from one person to another, read and control minds. She can also transform herself into an organic diamond which allows her to hold or lift exceptionally heavy loads and be insusceptible to injury. It was probably good for the X-Men that Emma Frost became an ally.
1 Dark Pheonix
Dark Phoenix, also known as Jean Grey, is a mutant and empath with the ability to experience the emotions of other people and to manipulate them. The power of telepathy was too intense for her to use, so Professor X blocked Jean Grey's access to it, choosing to teach her telekinesis instead. Her powers are so monumental, that she was able to resurrect herself without the phoenix, leading her to believe sh's no longer human. As a powerful mutant, Jean Grey has done some unfortunate things, and there is no questioning that if you're against her you're in a lot of trouble.
