Marvel's Infinity War is shaping up to be one of this year's biggest movies at the box office, but with two months left until this blockbuster-to-be hits theaters, there is still much we don't know about this superhero adventure. New merchandise details were just revealed on the Toys 'r Us website, including new details about Captain America (Chris Evans), Spider-Man (Tom Holland) and particularly the primary villain Thanos (Josh Brolin), which ultimately confirm Captain America's Secret Avengers will be featured in the movie. There will be some potential SPOILERS below, so read on at your own risk.

The Toys r' Us website features a number of different Avengers: Infinity War products that will be available for purchase, including action figures for Captain America, Spider-Man, Iron Man (Robert Downey Jr.), Thor (Chris Hemsworth), Hulk (Mark Ruffalo), Star-Lord (Chris Pratt), Groot (Vin Diesel), Black Widow (Scarlett Johansson) and even an Infinity Gauntlet that you can wear yourself. The page also features a section that includes bios for a number of Infinity War characters, with the Captain America bio revealing that he has remained "under the radar" since opposing the Sokovia Accords, although he continues to do what he thinks is right, which is, "saving the world one clandestine mission at a time," which ultimately confirms the Secret Avengers will be part of the story. The accompanying artwork also features a glimpse at the massive claw hands he was seen wearing in the Avengers: Infinity War trailer.

In the Marvel comics, the Secret Avengers were a black-ops team of superheroes that first came together in 2010, lead by Steve Rogers, with the team also including characters like Beast, War Machine, Valkyrie, Moon Knight, Nova, Black Widow, Sharon Carter, and Ant-Man, although it isn't clear who will be part of the Secret Avengers in the movie. The character bios also featured Thanos, which may feature the most surprising details. Here's the full Thanos bio from the Toys 'r Us website.

"The Avengers are brought face-to-face with the cunning, intelligent and fierce warlord, Thanos, a ruthless cosmic threat consumed with saving the universe from itself. To stop him, the Avengers must join forces with the Guardians of the Galaxy, Doctor Strange, and Spider-Man to bring down this villain who will stop at nothing to collect the six Infinity Stones."

The notion of Thanos "saving the universe from itself" falls in line with the first trailer, where he states that he's trying to "balance the universe", but this new description offers a bit more context. It's possible that Thanos' plan is similar to Ultron's, who determined that humanity must be destroyed in order to save the planet, but it is not known if there is any connection to Thanos and Ultron's former plans. Still, it's an interesting notion to consider as we get closer and closer to the May 4 release date.

The Spider-Man bio actually introduces him as Iron Spider, with a glimpse at the Iron Spider suit designed by Tony Stark/Iron Man (Robert Downey Jr.), although the character bio doesn't reveal much, stating that he must use his, "wit, strength and Spider Sense" to help the Avengers stop Thanos from getting all six of the Infinity Stones. The Black Widow bio states that she has been "on the run" since the Avengers disbanded. The Hulk bio adds that Bruce Banner is still struggling with his alter-ego and that, "he needs to make peace with who he truly is" if he is to help the Avengers beat Thanos. The final bio on the 'r Us website is for Thor, revealing he is, "still striving to earn his worthiness" and will be put to the test when Thanos arrives.
