Who are the new characters in Marvel's The Avengers: Age of Ultron?

So now that you've seen Avengers: Age of Ultron and are now about to buy the blu-ray, you may be wondering who are these new characters, and what do they have to do with the main story. Well never fear, true believers, your favorite Marvel nerd is here to explain it all for you.

Needless to say, this article is chock-full of SPOILERS!

Sure we all know who Captain America is, but who are these new Avengers? If you're a comic book reader, you know who these characters are. While they don't have the exact storylines they do in the comics, their roles are remarkably similar.

The twins: he's fast and she's weird. In the comics, the twins are the children of the mutant villian Magneto. After witnessing his power, their pregnant mother fled and found herself at Wundegore Mountain, where she delivered her children before dying. They were adopted by the Maximoffs and lived peacefully until their mutant powers emerged. Fleeing an angry mob, they were rescued by Magneto, who didn't know they were his children. For a while they were reluctant members of Magneto's Brotherhood of Evil Mutants and clashed often with the X-Men. Eventually, Magneto was transported off world and the twins decided to turn a new leaf and join the Avengers.

Since the film rights to the X-Men, and by extension Magneto and the concept of mutants, are currently owned by Twentieth Century Fox, the film can't mention that their powers are mutant powers or their father is Magneto. In the film, the twins volunteered to gain enhanced abilities through Hydra' experiments with Loki's scepter.

In the film, the Avengers are assisted by Dr. Helen Cho. In the comics, she is the mother of Amadeus Cho, a young prodigy who is known as the "7th smartest person in the world. After winning a contest, the family became a target. Their house was attacked and Helen and her husband were killed in an explosion.

Although a minor role in the film, in the comics Strucker is one of Captain America's oldest foes, beginning in World War II. After the war he helped found Hydra and became their leader. He has twins, who became the mutants known as Fenris.

Strucker clashed often with Nick Fury and S.H.I.E.L.D. as well as Captain America once he was defrosted.

The son of a Nazi war criminal, Klaw was raised on stories of Wakanda, a mysterious African nation which shunned outsiders, and is the only known location of Vibranium, the metal in Captain America's shield. He was hired to assasinate T'Chaka, the King of Wakanda. Although he was sucessful, he was forced to retreat by T'Challa, the king's son. His hand was injured during the attempt and he later replaced it with a sonic weapon

He clashed often with the Black Panther and the Fantastic Four. He leapt into a massive sonic converter device, transforming him into a being of living sound and becoming mentally unstable.

Although her name was not mentioned and only credited as Madame B, Julie Delphy's character could be Dr, Lyudmila Kudrin. Kudrin is the head scientist who developed a variation of the Super Soldier Serum which was given to Black Widow, who in the comics was born in the forties and still appears as a young woman

She works for the Red Room, which was the KGB's secret program for recruiting and training young girls for espionage in service to the Soviet Union. The Red Room was seen during the first season of Agent Carter.

In the comics, the Vision is the creation of Ultron, who sends him to fight the Avengers and Ultron's own creator, Dr. Hank Pym, but he is convinced to turn against Ultron and joins the team. Throughout his time with the Avengers, he tries to understand humanity. He meets the Scarlet Witch and the two fall in love and marry. Later, he would be disassembled and reassembled several times, at one point becoming stripped of his personality and emotions.

So now you're up to date. Stay tuned for Marvel's Ant-Man!
