Marvel has confirmed the official "Captain America: Civil War" teams.

Under Tony Stark a.k.a. Iron Man's Pro-Registration team are Natasha Romanoff a.k.a. Black Widow, James Rhodes a.k.a. War Machine, T'Challa a.k.a. Black Panther and Vision.

On Steve Rogers a.k.a. Captain America's Anti-Registration team are Bucky Barnes a.k.a. The Winter Soldier, Sharon Carter a.k.a. Agent 13, Sam Wilson a.k.a. Falcon and Scott Lang a.k.a. Ant-Man.

Details are still being kept under wraps on which of the "Captain America: Civil War" teams Spider-Man (played by Tom Holland) will join. Scarlet Witch (played by Elizabeth Olsen), who blames Tony Stark for the death of her parents, is expected to side with Captain America's team.

Olsen, whose character was introduced in "Age of Ultron," teased what fans can expect from the film

"I think [Captain America: Civil War is] going to be the best one. For real, I am very excited to see it myself," Olsen told Premiere.fr. "I only worked on set for five weeks. So I wasn't there for the majority of it."

The 26-year-old star also confirmed that Daniel Brühl's character Baron Zemo is the movie's main antagonist.

"[Daniel] Brühl is an incredible actor and he's playing the main villain in it," she revealed. "And he's incredible! It's a movie about people as opposed to robots this time. So it's darker and it's allowed to be darker because it gets more in the mindset of humans rather than machines."

The movie features Chris Evans as Captain America, Robert Downey Jr. as Iron Man, Sebastian Stan as The Winter Soldier, Paul Bettany as Vision, Anthony Mackie as Falcon, Jeremy Renner as Hawkeye, Scarlett Johansson as Black Widow, Paul Rudd as Ant-Man, Chadwick Boseman as Black Panther, Don Cheadle as War Machine, Frank Grillo as Crossbones and William Hurt as General "Thunderbolt" Ross.

"Captain America: Civil War" releases in theaters on May 6, 2016.
