We've already know that Loki is supposed to be the villain in the Avengers, that he gets a hold of the cosmic cube, and summons an alien invasion force (Kree or Skrulls).
Now, Latino Review states there is another "Big" villain - and it's THANOS!
They state it as fact, too.
It does fit with what we have seen in Thor, as the post-credit scene showed Loki controlling Erik Selvig as Nick Fury revealed the cosmic cube.
Also, the Infinity Gauntlet was shown as a treasure in Odin's treasure chamber -- and was first revealed at last year's San Diego Comic Con.
Just what role is Thanos going to play? And what the heck is the Infinity Gauntlet?
Well, if you read the comics (we do!) you know Thanos is the Mad Titan who's love for Death (yes, an actual entity) is matched by none (who would love death, anyway?!). Thanos acquires the six Infinity Gems and when combined -- they give him control over all time, space, reality, power, mind and soul.
In essence, Thanos is the king of the entire Universe -- or god! Thanos ends up killing off half the population of the Universe as a way to show his love for Death.
Yeah, the guy is a powerhouse, like none other -- and I can't see the Avengers even standing a chance!
I could see Loki bringing the Kree or Skrulls to Asgard/Midgard and during the attack, the Infinity Gauntlet somehow gets out of Odin's treasure chamber, which might have acted as a shield from prying eyes (Thanos). Once it's out of the chamber, Thanos takes notice and heads for Asgard and Earth!
Maybe, this is a set up for "Avengers 2" -- as the Avengers would need some heavy hitters to help out.
Marvel Studios President and Producer, Kevin Feige, did mention a Guardians of the Galaxy movie!
Also interestingly enough, Marvel has put their recent cosmic line on "hiatus." Could they be re-launching the line to follow the Avengers movie in 2012?
The Avengers hits May 4th, 2012 and is directed by Joss Whedon, starring Robert Downey Jr. as Iron Man, Chris Hemsworth as Thor, Chris Evans as Captain America, Samuel L. Jackson as Nick Fury, Mark Ruffalo as the Hulk, Scarlett Johansson as the Black Widow and Jeremy Renner as Hawkeye.
