Collider:

With Idris Elba replacing Will Smith as Deadshot in The Suicide Squad, it’s now time for writer-director James Gunn to turn his attention to filling out the rest of the ensemble, and while we haven’t heard any names except for the obvious one below, we have learned which characters are expected to comprise the rest of the squad. A rewrite could, of course, change things, so keep in mind that none of this is confirmed, it’s just what we’re hearing from sources right now. Let’s dive in, shall we?

Ratcatcher, aka Otis Flannegan, is a man in the DC comics, though Collider has learned that the character will be gender-swapped and played by a woman in The Suicide Squad. Ratcatcher is is a super-criminal and one of Batman’s many enemies. She started out as an exterminator in Gotham City before turning to a life of crime, aided by an army of small rodents she can communicate with and control. She’s also a fan of poisonous gas.

Nanaue, aka King Shark, is a super-villain and humanoid shark whose father is believed to be the so-called Shark God, though others dismiss him as merely a savage mutation.

Polka-Dot Man, aka Mister Polka Dot, is a Gotham City super-villain and like Ratcatcher, a sworn enemy of Batman. He grows multi-colored polka dots on his body that he can turn into fireballs and other weapons, even though, for the most part, he’s embarrassed about his awkward abilities.

Peacemaker, aka Christopher Smith, is an agent of peace whose motives are driven by an extremist form of pacifism that makes him love peace so much he would kill for it.

Sounds like a crazy bunch to have in the flick!

Per Collider, Dave Bautista is in the running for Peacemaker.

I’m really wondering how they’ll pull off King Shark.
