Black Widow

At Comic-Con 2010, newly appointed Avengers director🥀 Jo💎ss Whedon assembled the principal cast of his forthcoming movie on-stage.

Notably, the only woman was Scarlett Johansen, reprising her Iron Man 2 role of S.H.I.E.👍L.D. agent Natasha Romanoff, aka Black Widow.

Who will join Scar-Jo in the 2012 moviꦰe? Looking at Marvel's illustrious history, there is no shortage of ♉candidates to help or hinder the Avengers...

Wasp

The Comic-Book Character: Heiress Janꦚet van Dyne was moved to fight crime after an alien monster killed her father.

Injected ꩲwith the same particles that powered Ant Man, she can shrink, grow wings and hire energy blasts from her wasp's 'sting.'

The Movie Version: As one of the founding members of The Avengers in p🅺rint, she's bound to get a look-i🌳n at some point.

It'd be fun to seed her backstory as a spoiled princess who will come good in future movies, whether it be The Avengers' sequel or Edgar Wright's in-the-pipeline Ant Man movie.

Played By: Recent rumours suggest that Eva Longoria has screen-tested for the role๊, and her s🥃exy/spiky persona could well be worth a punt.

Typhoid Mary

The Comic-Book Character: Mary Walker is mentally ill, with three distinct personas: timid ꧙"Mary," violent"Typhoid" and brut🍒al "Bloody Mary.

Helpfully, she's also telekineti🎃c, making her extremely useful as an assa𒐪ssin.

The Movie Version: Already a bit disturbed, Walker is nearly killed during one of the Hulk's rampages and mista🎉kenly believes him and his fellow Avengers to be villains.

So she sides with criminal 🥀organisation HYDRA to get her revenge.

Played By: 🌺A punk'd up Drew Barrymore could pullꦏ off the necessary street-trash aura.

She-Hulk

The Comic-Book Character: Originally a lawyer, Jennifer Susan Walters developed the angry-green gene after cousin Bruce Bannerཧ had to give her a blood transfusion.

The Movie Version: Keep tight to the backstory. Walters is a minor character, providing legal counsel for the team and giving Mark Ruffalo'♉s Bruce somebody to spar with.

When tragedy strikes, he gives blood but, in 💎a last-minute twist,🐼 Jennifer starts to show signs of Hulking out.

Played By: Eva Mendes

Photon

The Comic-Book Character: Monica Rambeau💝 is capable of transforming herself into any kind of energy: electricity, radiation, cosmic rays, you name i🦋t.

This 𒐪makes her capable of nifty tricks like invisibility, flight and powering toasters.

The Movie Version: With all that kit, the Avengers are going to need somebody to keep the fires at HQ burning♏. Movie Photon is the team's sparkplug.

Played By: Taraji P. Henson

Sharon Carter

The Comic-Book Character: S.H.I.E.L.D. operative Agent 13, she's also the niece of Captain America's origജinal wartime lover, Peggy🐽 Carter.

The Movie Version: With Hayley Atwell already playing Peggy Ca✤rter opposite Chris Evans's Steve Rogers in The First Avenger, there's scope for a neat gag as the Captain finds her descendant working for Nick Fury in the present day.

Played By: Hard to resist giving Atwell a second role.

Scarlet Witch

The Comic-Book Character: Wanda Maximoff is🦄 the daughter oඣf Magneto. Yes, that Magneto.

In the comics, this villain-turned-🐭Avenger can warp reality, which pretty much means she can do anything.

The Movie Version: Largely responsible for capturing the A💝vengers by mid-movie, it turns out she despairs of the depths of depravity to which her fellow villains are capable, so helps the Avengers to escape.

Played By: Monica Bellucci

Mockingbird

The Comic-Book Character: Barbara 'Bobbi' Moore has nothing to do with England winning the World Cup𓃲. She's yet another S.H.I.E.L.D. agent: no🧜 superpowers but an expert fighter nonetheless.

The Movie Version: Considered one of S.H.I.E.L.D's finest at the film's start, she inadvertently stumbles upon HYDRA's big scheme and is offed🎐 in a killer early twist, kickstarting the Avengers' ad꧃venture.

Played By: Sienna Miller.

Spider-Woman

The Comic-Book Character: Jessica Drew isn't related to Peter Parker, although her roots are similar (radiation + spiders = S🎐pidey-powers).

Where she truly parts company from the good guys is that she was recruited by HYDRA and, initally ༒at least, fought the Avenge🦩rs.

The Movie Version: The Avengers are🌃 in a pickle and hear the telltale swish of Spidey web-slingers. Saved!

...Or, at least they think they are until Spider-woman swings by 💧on the bad ꧟guys' side.

Played By: Anne HathaWay

Skrull Queen

The Comic-Book Character: Queen Veranke is leader of the villain🌊ous alien Skrull and, like them, a shape-shifter undetectable by the Avengers.

The Movie Version: Tweaking a plot twist from Marvel's Secret Invasion arc, it turns out that Veranke is impersonating Black Widow and has gained access to the inner circle of th💝ಞe Avengers.

A co๊mplication they don't need given their battle ag🌳ainst HYDRA.
