After Captain America: Civil War, the Avengers effectively split up and scattered after choosing to side with Iron Man or Captain America during that conflict, and it can be difficult to keep track of where everyone is. So take a look below to find out.

We last saw Iron Man in Spider-Man: Homecoming, where he mentored a young Peter Parker. At the conclusion of Civil War, his only real ally remaining besides Spidey was War Machine, who was still recovering from his injuries.

We last saw Cap in Civil War (not counting his filmed cameos in Homecoming), breaking his fellow former Avengers out of prison and dropping Bucky off in Wakanda. Black Widow, who sided with Iron Man in Civil War before turning on him, has gone into hiding, but eventually joins forces with Cap and Falcon during Infinity War. Hawkeye and Ant-Man, who sided with Cap in Civil War, are not confirmed to appear in Infinity War.

Black Panther, Okoye, and Shuri will all play key roles in the film — as will Bucky Barnes, who was revealed to still be rehabbing in the African nation in a Black Panther post-credits scene. Bucky will also receive a new metal arm at some point, presumably one made of vibranium.

At the end of Guardians of the Galaxy: Vol. 2, the team had acquired two new members in Mantis and Nebula. Both Nebula and Gamora are the adopted daughters of Thanos, meaning they know the villain better than any other Marvel heroes. Infinity War will mark the first time the Guardians meet any of Marvel's other characters.

These two Avengers took opposite sides in Civil War, but made up before the battle was even over. The pair had a budding romance in that film, and are presumed to be on their own together in Infinity War.

Thor, Hulk, and Loki took the surviving Asgardians from Asgard at the end of Thor: Ragnarok, with the intention of settling on Earth. However, they don't make it, as a post-credits scene revealed that they encountered Thanos' ship. Also on that ship were Valkyrie, Korg, and Heimdall, but it's unknown if they appear in Infinity War.

Strange was last seen in Ragnarok, where he appeared even more powerful than in his solo film. He's still based in New York, where he acts as the guardian of that city's sanctum.

Thanos needs to collect six Infinity Stones, and he'll need to travel a bit to do so. Here are their last known locations.

Also known as the Tesseract and first seen in Captain America: The First Avenger, it was placed in Odin's vault on Asgard at the end of The Avengers. However, Loki spied it in Thor: Ragnarok while in the vault, and he presumably stole it. This could explain why Thanos confronts the Asgardians' ship.

This stone first appeared in Loki's scepter in The Avengers, which he received from Thanos, and it now resides in Vision's forehead. This is likely very bad news for Vision.

This stone first appeared as a powerful mist called Aether in Thor: The Dark World. In that film's post-credits scene, it was brought to The Collector for safekeeping. It's unknown whether he still has it after his headquarters was destroyed in Guardians of the Galaxy.

The MacGuffin in Guardians of the Galaxy, Thanos hired Ronan to obtain this stone for him in that film, but Ronan kept it for himself. He was defeated by the Guardians, who then entrusted the stone to the Nova Corps on Xandar.

First seen in Doctor Strange as the Eye of Agamotto, Strange currently wears this stone around his neck. Like Vision, he could be in serious trouble because of this.

The only stone to not yet appear in a Marvel film, its current whereabouts are unknown, though some fans theorize it's in Wakanda (that would explain the meteor that injected the country with vibranium) since Thanos invades the nation in Infinity War.

Thanos is obviously the big bad here, having been lurking in the shadows of the MCU since his introduction in the post-credits scene of The Avengers, but he won't be acting alone.

The movie is said to be about Thanos, with the Avengers as supporting characters, so we'll be learning a lot more about him. So far, we know he's one of the most powerful beings in the galaxy, has two adopted daughters who hate him, and wants to eliminate half the life in the universe.

Thanos' powerful alien henchmen, of which there are four. Ebony Maw, seen in the above gif, has powers of manipulation. Cull Obsidian (called Black Dwarf in the comics) is a brute with strength comparable to the Hulk's. Proxima Midnight is the lone female member, and she possesses a spear of near-limitless power. Lastly is Corvus Glaive, who also has a superweapon: a blade that keeps him immortal. The Black Order were introduced in the 2013 comics storyline "Infinity," from which the movie also draws some influence.

These alien soldiers make up Thanos' army, and they're quite savage fighters with six arms and strong jaws. They were also introduced in "Infinity," where they possessed the power to turn invisible. It's unknown if they'll display this power in the film as well.

Loki's allegiance will likely shift throughout the film, since this is Loki we're talking about, but the film's trailers do show him standing alongside the Black Order at one point.

Without delving too much into rumor territory, the trailers have shown Iron Man and Bruce Banner meeting Doctor Strange and Wong in New York; Thor meeting the Guardians and subsequently branching off with Rocket and Groot; Captain America, Black Widow, Falcon, War Machine, Hulk, Scarlet Witch, Vision, and Bucky fighting alongside Black Panther and the Wakandans against Thanos and the Outriders in Wakanda; Iron Man, Doctor Strange, Star Lord, Drax, and Spider-Man meeting on another planet; and Vision having his Infinity Stone ripped out of his head by Corvus Glaive; among other things (phew).

This movie, which opens on April 27 and has a runtime of two hours and 40 minutes, has a lot going on, so study up before heading to the theater to avoid becoming hopelessly lost.
