Okay, first up are the little hunks of plastic from this board game The Avengers: Mighty Battle, a "Skill and Strategy" game on display at Toy Fair.  Against, spoilers here. MTV Geek was on hand to pick up these images of characters who look very much like the Skrull, those Marvel Comics baddies who have long been rumored to be the army Loki calls down on Earth.  In all likelihood, nobody's going to actually use the word "Skrull" in the film, but shapeshifting aliens are likely to be present.

Okay, and now, thanks to Collider, we've got some official images and descriptions of LEGO sets depicting sequences from The Avengers.  Check out each big of LEGO goodness and the descriptions, but again, be wary of the spoiling going on.

Quinjet Aerial Battle

Loki is up to no good and is planning to destroy the earth! As he flies into battle on board his chariot, help the Avenger’s defeat their nemesis using the supersonic Quinjet! Fire the missiles, release the mini-jet and imprison Loki in the prison pod! With the high-tech Quinjet, the Avengers can’t fail! Includes Thor, Iron Man, Black Widow, Loki and more minifigures.

Loki's Cosmic Cube Escape

Loki is escaping from S.H.I.E.L.D. headquarters with the powerful Cosmic Cube. If he succeeds, he could use it to wreak havoc on the world! Will Iron Man in his amazing armored suit alongside Hawkeye in his function-packed S.H.I.E.L.D. off-roader be fast enough to catch Loki, or will the Asgardian villain escape with the Cosmic Cube? You decide! Includes 3 minifigures: Iron Man, Loki and Hawkeye.

Captain America's Avenging Cycle

While riding his Avenging Cycle, Captain America spots the general on his craft. Help Captain America use his indestructible shield to defeat the general and his foot soldier! Win the battle and send them back to where they came from. The fate of the world lies in your hands. Includes 3 minifigures: Captain America and more.

Note the way-ambiguous designations there, like Cap facing off against 'the general,' implying a bad guy with whom we're not yet familiar.  There are more images and descriptions over at Collider, so head over yonder to take a look.

The onslaught of The Avengers merchandise tie-ins should start next month, since the big team-up movie that Marvel's been building towards since 2008's Iron Man arrives in theaters on May 4th.  Chris Evans, Robert Downey Jr., Chris Hemsworth, Samuel L. Jackson, Tom Hiddleston, and Scarlett Johannson, and Clark Gregg all reprise their Marvel roles, along with newcomers Mark Ruffalo and Cobie Smulders.
