1. Black Widow

Everyone's excited about the release of The Avengers: Age of Ultron, so we've rounded up the absolute best Avengers cosplay from comic conventions across the country. Scarjo better watch out. This fan rendition of Black Widow is near perfect.

2. Iron Man

"Please, no gang signs." This guy's the spitting image of Tony Stark, down to the salt and pepper moustache and disapproving scowl. Way to go!

3. Scarlet Witch

The Scarlet Witch casts a transfixing hex on WonderCon in Anaheim.

4. Thor

Don't let her ease with the Mjolnir hammer fool you. That thing is heavy.

5. The Hulk

What this guy lacks in size he makes up for in sheer adrenaline fueled rage. There's no defusing this gamma bomb.

6. Loki

When Loki's not busy being the God of Evil, the notorious trickster actually has a contemplative side.

7. Nick Fury

Nick Fury politely poses for a picture, on a short break from fighting the forces of HYDRA.

8. Loki and Thor

Thor can barely hide his distaste over the indignity of posing with his adopted brother Loki. You just know it's gotta be another trap.

9. Black Widow and Hawkeye

Hawkeye's ready to defend his life long love Black Widow. He's always been a straight shooter.

10. Captain America

Steve Rogers prepares himself to take on Ultron, the sentient A.I. run amok. Avengers assemble!

11. Thor (and Rainbow Brite)

When the citizens of Rainbow Land need protecting from the King of Shadows, Thor is waiting in the wings.

12. Wolverine, Spider-Man, Captain America and Hawkeye

Wolverine and Spider-Man have yet to join forces with The Avengers in the movies, but with a rich history of comic book cooperation, their eventual participation seems inevitable.

13. Thor

Thor casually profers the jewel of Odin's treasure room. Hey buddy, you do realize the Tesseract can open a portal to the Chitauri army, right? You might wanna put that thing away.

14. Hawkeye

This Hawkeye's got a nice callback to the character's original regal color scheme from the comics.

15. Iron Man

We're pretty sure the stock price of Stark Industries just tripled when the world got a look at this excellent costume. This man means business.

16. Thor

Thor has no plans to die today. Especially not when he's got the best costume at the convention.

17. Captain America

His shield is nearly indestructible, but Captain America's got an even fiercer stare. You do not want to cross the first Avenger.

18. Loki

Loki prepares some black magic energy blasts. Asgard's resident God of Lies and Mischief does have a reputation to maintain, after all.

19. Thor

For once, Thor actually seems to be in a gaming mood. Whosever holds the hammer shall possess the power.

20. Captain America

If you're gonna fight a war, you've gotta wear a uniform. This one would make Steve Rogers proud.

21. Black Widow

Natasha Romanof may be the most popular Soviet defector in history. Where would S.H.I.E.L.D. (or comic conventions, for that matter) be without her?
