As if Batman vs. Superman wasn’t enough, now we have to deal with an entire superhero Civil War.

That’s right true believers. It’s time for Marvel heroes to duke it out with each other instead of beating up on Hydra, Thanos and Ultron.

In “Captain America: Civil War,” most of the Avengers, old and new, deal with the choices they made in their last big screen adventure – which ends up fracturing the supergroup.

In case you need a refresher from last summer’s “Avengers: Age of Ultron,” big brains Tony Stark and Bruce Banner (aka Iron Man and the Hulk) created artificial intelligence in the form of Ultron.

The goal? Protect humanity sans super-powered heroes.

Not So Civil Response

But the robotic Ultron determined that the best way to protect the earth was to eliminate the meddlesome human infestation. The Avengers – composed of Iron Man, Hulk, Thor, Captain America, Black Widow, Hawkeye and newcomers Vision, Scarlet Witch and Quicksilver – defeated this menace.

Doing so left much of the country of Sokovia in ruins.

In the aftermath, Quicksilver lay dead and some of the original team decided to take a breather, leaving Cap and Black Widow to train the next generation of heroes, including newcomers War Machine and Falcon. In the new movie, they’ll be joined by Ant-Man, seen in 2015’s eponymous film, as well as Black Panther and Spider-Man.

And while Hulk won’t be featured this time around, we’ll also see Thaddeus “Thunderbolt” Ross, who has been MIA since the Hulk’s standalone movie. Having retired from the Army, the former general is now the Secretary of State. He urges with the Avengers to comply with the Sokovia Accords, which places the team under the control of the United Nations. Iron Man, wracked with guilt over nearly ending all human life, argues that the Avengers should comply.

Cap, though, sees things differently and won’t agree to the accords. The battle lines are drawn, and the rest of the team must choose sides. With the brawn to back up their muscle, epic battles are sure to ensue.

While the comic book series the feature is loosely based on centers on the fight between Iron Man and Cap, the setup is somewhat different.

In the comics, a team of younger heroes called the New Warriors accidentally cause an explosion in Connecticut, killing hundreds of bystanders. The government passes the Superhuman Registration Act, forcing all “gifted” people to reveal their powers and identity to the government.

Similar to the movie, Iron Man supports the measure. World War II hero Cap can’t stomach the notion of people having to register their identities with the government.

The two sides fight several battles, including one in which Goliath is killed by the pro-registration forces. The comic book Civil War is also notable for Spider-Man’s decision to initially side with Iron Man and to reveal his secret identity to the world during a press conference.

That decision nearly cost Spidey’s dear Aunt May her life, but Peter Parker was able to turn back time after literally making a deal with a devil.

O Captain My Captain

The comics Civil War ended with Cap surrendering to avoid further bloodshed. Cap himself is seemingly assassinated while in federal custody a few issues later. While his death probably isn’t in the cards for the movie, directors Joe and Anthony Russo promised a gut-wrenching finale that will leave the team in tatters.

As true as that may be, chances are they’ll regroup in time to take on Thanos in 2018’s “Avengers: The Infinity War Part 1.”

“Captain America: Civil War” opens May 6.
