Heroes

Ant-Man / Can shrink to the size of an Ant-Man, but gets stronger as he gets smaller. Was once a professional thief
Batgirl / Barbara Gordon, daughter of Police Commissioner Gordon, was told not to be a police officer, decided to fight crime anyway. Crazy tech smart.
Batman / Billionaire Bruce Wayne, fights crime in Gotham City. Martial artist, tech man. Basically, the best.
Black Widow / Ex-KGB spy. Russian. Brilliant mind, fluent is multiple languages, master fighter. Can do everything the boys can do, but in high heels.
Captain America / Steve Rogers, was once a weakling, now a one man army. Super American, frozen from WWII until now.
Elektra / Female ninja in modern American with Greek origins. Talk about a melting pot.
Green Arrow / Billionaire Oliver Queen was stranded on an island, learned to live off the land. Returned to civilization with a new appreciation. Modern day Robin Hood.
Green Lantern / Given a magic ring, fights crime using pure will to create “light constructs” in the form of anything he can think of. If he can think it, it becomes real.

Iron Man / Billionaire weapons designer Tony Stark built an advanced suit of armor to fight bad guys. An original Avenger.
Ms. Marvel / Kamala Khan teenage Pakistani American from New Jersey with shapeshifting abilities. Emphasis on 2015 teenager. Selfies!

Raven / Member of the Teen Titans, is half demon. Has supernatural powers. Kind of the ultimate goth chick.
She-Hulk / Female version of the Hulk. The angrier she gets, the bigger and stronger. Mean, green fighting machine.
Spider-girl / Female version of Spider-man. Spider powers, shoots webs. You know the deal.
Spider-Man / Bitten by a radioactive spider, gained heightened senses and spider powers, but not any new social skills. Peter Parker is a nerd.
Superman / The prototypical superhero. Laser vision, ice breath, can fly, super strong. Truth, justice, and the American Way! Avoid kryptonite.
The Falcon / Soldier with a pair of wings to help him way. Next in line to be Captain America. Military all the way.
The Flash / Fastest man alive. Really. Runs super fast, sometimes back/forth in time. In his off time, is a crime lab tech.
The Hulk / Bruce Banner grows in size and strength the angrier he gets. And greener
The Thing / Affected by gamma radiation, acquired rock traits and rock strength. From Jersey, means business. It’s clobberin’ time!
Thor / God from Asgard, guardian of the realms. ‘Tis nobly he speaks! OFTEN IN ALL CAPS! In the comics, sometimes a woman is Thor. Eh, it’s 2015, not all that weird.
Wolverine / X-Man main guy. Canadian. Super healing powers and metal knives shoot from his knuckles. Oh yeah, and a metal skeleton.
Wonder Woman / Born from clay, an Amazon goddess. Has a lasso that forces people to tell the truth, and bracelets that deflect bullets. Girl power!

Villains

Captain Cold / Has a freeze ray, likes to rob banks and terrorize the city. Very little patience. Pretty evil.
Catwoman / Master burglar, jewel thief, and enemy (sometimes girlfriend?) of Batman. She sly, quick, and she knows she’s awesome.
Cheetah / Half-woman, half-wild cat. Quick, angry, deadly. Claws on her fingertips are sharp!
Deathstroke / Master marksman, a glorified hired gun. Has some ninja training. Only loyal to the money.
Doctor Doom / Leader of a ex-soviet nation, crazy smart. Hit by gamma radiation and got smarter and crazier. One of the worst bad guys. Gnarly metal mask on his face, no sense of humor.
Doctor Octopus / Metal arms attached to his spine, Spider–man’s worst nightmare. Also a scientist, mega-corrupted by evil. Cool sunglasses though.
General Zod / From same planet as Superman, same powers as Superman, super evil (not like Superman!). Wants to kill humans to by new homeworld. Not cool, dude.
Giganta / 240 foot tall woman, also quiet strong. Hard to fit in a room, easy to be squished by.
Green Goblin / Super rich dude who doesn’t fight crime but causes it. Slighlytkukoo, slightly green, has crazy gadgets. Weird laugh, too.
Harley Quinn / Former psychotherapist HarleenQuinzel, was turned to the bad side when she fell in love with The Joker. Dresses as a sort of jester, very childish, very dangerous.
Killer Croc / Half-man, half-crocodile. Well, mainly crocodile man. Waylon Jones means business when he tries to snap your face off.
Lex Luthor / Billionaire, president (at least once), bald. Arch enemy of Superman. Always buying kryptonite and real estate.
Loki / Trickster god from Asgard, Thor’s brother. Basically messes things up for personal gain and for fun.
Magneto / Bad guy mutant that can control anything made of metal with his mind. Rival to Professor X, oh, and also hates humans.
Megatron / Leader of the Decipticons. Think of giant evil robot man. That’s Magetron.

Red Skull / Super evil Nazi man obsessed with the supernatural. Enemy to Captain America. Because he’s a Nazi. And evil. Double evil guy. With a red skull.
Scarecrow / Bad guy who created a toxin that makes you go crazy with fear. Dresses like a scarecrow, which is scary enough for me. Batman and him are NOT friends.
Shredder / Master ninja and enemy of the Teenage Mutants Ninja Turtles. Lots of swords and jumping.
Sinestro / Has a magic ring like the Green Lantern that can make anything appear, but powered by fear and evil. Stupid yellow.
The Joker / The Clown Prince of Crime. Absolutely insane. Might kill you, might not. No predictability. Laughs a lot at his own jokes. Batman’s main bad guy.
The Penguin / Another Batman villain. Business man by day, gun smuggler by night. Waddles around a lot, eats raw fish. British.
The Riddler / Always telling riddles to trick Batman. Never wins. Like a discount Joker.
Two-Face / Was a District Attorney, hit with acid on half his face, and now looks gnarly and consumed by his coin to decide his enemy’s fates. Heads you live, tails you don’t.
Ultron / Robot made by the Avengers to help stop crime, actually becomes self-aware and wants to kill the Avengers. And you thought teenagers were bad.
Venom / Weird alien ectoplasm, infects to body and tries to kill everything. Copied Spider-man once and wears a black version of his costume ever sense. Kind of like a weird, creepy homage. Gross.
