THE SUICIDE SQUAD is a new chapter in the story of the criminals and anti-heroes who are coerced into doing good by a shadowy government agency. A few big characters — led by Margot Robbie's Harley Quinn — return from the 2016 movie SUICIDE SQUAD, and they are joined by a whole host of newcomers.

The character lineup of THE SUICIDE SQUAD is so dense that it's even hard to keep track of who shows up in the trailers. That's where this article comes in; we've got the complete rundown on all the important characters in the new SUICIDE SQUAD movie. Given the name of the film it's a safe bet that some won't make it to the end credits, so print this out, make a checklist, and get ready to save the world!

THE SUICIDE SQUAD writer/director James Gunn has already demonstrated his ability to quickly introduce and create empathy for a wide range of unusual characters. That being the case, the first two GUARDIANS OF THE GALAXY were a cakewalk compared to this new movie, which features one of the greatest collections of weirdos we've seen on the big screen in a long time. Here are the new ones.

Bloodsport (Idris Elba)

Don't call Idris Elba's Bloodsport a replacement for Will Smith's character Deadshot from the original movie, but such a thing would be entirely in the ethos of these movies. Bloodsport is great with a gun. He's a somewhat broken and crazed killer who, in comic books, was originally introduced in a story that saw him shooting kryptonite bullets at Superman. Here, he's a little more grounded.

Tyla (Storm Reid)

Storm Reid's Tyla is the daughter of Bloodsport. That means she probably plays a small role, but we're happy to see the star of A WRINKLE IN TIME show up regardless.

Savant (Michael Rooker)

THE SUICIDE SQUAD director James Gunn almost always works with actor Michael Rooker, so you knew he would have a place here. Savant has a couple of incarnations in comic books and was originally a wealthy Batman wanna-be. This movie version seems to be based on DC's "New 52" stories that kicked off in 2011, which placed Savant in the Suicide Squad lineup. Basically, he's mean and has one heck of a head of long white hair.

Polka-Dot Man (David Dastmalchian)

David Dastmalchian's Polka-Dot Man was originally a fairly goofy-looking guy from 1960s Batman comics who just wanted to be noticed by the Caped Crusader. To that end, he placed strange technological traps around Gotham City and used bizarre weaponry, all based on the visual motif of spots and dots. In THE SUICIDE SQUAD, he's a dangerous and repressed guy with serious unresolved mommy issues.

(David Dastmalchian has already appeared in THE DARK KNIGHT as a different character, and we presume there won't be any link established between his two roles.)

Peacemaker (John Cena)

John Cena's Peacemaker was originally a guy who developed his peaceful worldview to an unhealthy extreme. The character has been around for decades, in various versions, but the look we see Cena sporting in the movie goes all the way back to Peacemaker's 1967 comic book debut. He's everything you would expect from a single-minded idealogue: Unintentionally hilarious and almost foolishly violent, but also useful in a fight.

Javelin (Flula Borg)

Flula Borg's Javelin is an athlete-turned-criminal who uses his sporting background to wield — you guessed it — javelin-based weapons.

Thinker (Peter Capaldi)

Peter Capaldi's Thinker is probably Clifford DeVoe, the first man in DC Comics history to use the Thinker name. He was a lawyer who spun a bit of unpolished technological know-how into a criminal career. In THE SUICIDE SQUAD, he's more of a mad scientist who has been working on a potentially world-destroying project. Initially an inmate at a Nazi prison/research facility called Jotunheim, located in the nation of Corto Maltese, Thinker escaped but ultimately worked as a scientist at Jotunheim, which brings him into contact with Task Force X.

Ratcatcher 2 (Daniela Melchior)

Based on the name alone, Daniela Melchior's Ratcatcher 2 seems like a successor to the DC Comics character Ratcatcher, who claimed to talk to rats and used his fascination with rodents as a means to terrorize Gotham. We know that Ratcatcher 2 does in fact communicate with rats in this movie — it's right in the trailer — and we wonder how that plays into one shot of rats swimming by Harley Quinn while all are under water.

King Shark (Steve Agee and Sylvester Stallone)

Is King Shark a great character, or the greatest character? The comic book version was the child of a shark god and could basically do all the things sharks can do, only on land. The character was originally slated for the first SUICIDE SQUAD movie. The effects to bring him to life proved to be overwhelming at the time, so Killer Croc was swapped in. He looks beautiful here.

TDK (Nathan Fillion)

Nathan Fillion's TDK is an unusual fellow whose three-letter-moniker may stand for "The Detachable Kid." He's based on Floyd "TDK" Belkin, a briefly-seen late '80s character who wanted to join the Legion of Super-Heroes. His power? He could pull off his arms and use them as clubs. Presumably, he couldn't wield both arms at once. The bizarre would-be Legionnaire was originally called Arm-Fall-Off-Boy and was inspired by a fan-made parody.

Mongal (Mayling Ng)

The orange-skinned Mongal is an alien from Warworld, which sounds like a planet but is actually a giant galaxy-roaming ship that is pretty much entirely dedicated to gladiatorial combat. Mongal was a champion on Warworld, but somehow ended up imprisoned on Earth, which leads her to Corto Maltese.

Starro (Starro)

Starro is a starfish-shaped alien. It (he?) is almost cute and also extraordinarily dangerous.

Sol Soria (Alice Braga)

Sol Soria is a relative mystery but we know that Alice Braga's character a native of the small country of Corto Maltese. She leads the Resistance against dictator Silvio Luna, which helps her interests align with those of Task Force X, aka the Suicide Squad.

Blackguard (Pete Davidson)

Pete Davidson's Blackguard is a criminal enforcer who joins the Squad.

Weasel (Sean Gunn)

Sean Gunn's Weasel may be based on a minor 1980's comic book character, but everything you need to know about the strange character is right there in his look and tic-laden movements. (He might have actual ticks, too, but we're not sure about that.)

While THE SUICIDE SQUAD tells a story that is almost entirely separate from the previous movie, there are a few important characters returning for Round 2. One of them is almost impossible not to know at this point so we'll leave her for last. Here's the veteran crew.

Amanda Waller (Viola Davis)

Amanda Waller runs the government agency that doles out missions to Task Force X — and which imposes severe penalties for using the cover of a mission to make an escape. She's a force to be reckoned with.

Captain Boomerang (Jai Courtney)

If there's any one character who didn't quite get his due in the original SUICIDE SQUAD it is this rakish and unpredictable anti-hero. His whole schtick is right in his name — but will his attempt at redemption swing back around to knock him out again?

Rick Flagg (Joel Kinnaman)

Joel Kinnaman's Rick Flagg is a version of the character who led the Suicide Squad in comic book stories for years. On the big screen he has his hands full trying to wrangle some very large and nearly uncontrollable personalities.

Harley Quinn (Margot Robbie)

You know her, you love her! Harley Quinn is back and while this isn't exactly her movie, she plays a huge role in the new story. Will this be the most unfettered outing for Harley yet? Bet on it.

THE SUICIDE SQUAD opens on August 6!
