Harley Quinn’s cinematic social circle will be getting a lot bigger when the Suicide Squad spin—off, Gotham City Sirens, hits theaters. The film — executive produced by Harley actor Margot Robbie and directed by Squad’s David Ayer — will most likely be based on the comic series of the same name, which follows the story of Harley Quinn, Poison Ivy, and Catwoman teaming up to accomplish their bad gal goals.
DC’s Gotham City Sirens also features a heavyweight cast of eccentric characters — villains and regular Joes alike — that makes it the perfect place to handpick individual personalities from the flock. Despite the huge supporting cast, the series rarely feels overloaded despite its many, many cameos. The unruly nature of the plot will either be the wildcard Ayer and DC desperately needs or, much like Suicide Squad, be the thing that kills it in the box office.
So, we picked through the entirety of the Gotham City Sirens series and created a list of characters that would be great in a film. Harley, Ivy, and Selina Kyle’s Catwoman are obviously going to be featured in a Sirens film (we would hope), so they’re missing from this list despite their importance. Happy snooping, puddin’!
1. The Broker
Known only as “The Broker,” this generically suited, sunglassed man finds elaborate, perfectly suited housing options for criminals in abandoned warehouses, former pet shelters, old hospitals … You get the picture. If you ask him, he specializes “in eclectic living spaces for eccentric clients,” but that’s neither here nor there. The Broker finds Harley, Ivy, and Selina a place to live several times throughout the series, so if the Sirens film is in the market for an age-old sanitarium, they should know where to look.
As the gag-tastic former sidekick to the Joker, Gagsworth A. Gagsworthy, aka Gaggy, is a little bitter. Gotham City Sirens has him turning the Joker’s former lair of slapstick gags and pranks into a shrine, impersonating the Joker, and trying his hardest to take out Harley Quinn. He’s jealous of her dealings with Mr. J, and after having already been replaced once in Harley’s Circus by the Flying Graysons, he’s got a bit of a chip on his hunched shoulder.
If Gotham City Sirens is looking for a B-plot villain with the means to even further complicate the already complicated personal relationships in the film, they need look no further than Gaggy.
3. Poison Ivy’s sporelings
When Poison Ivy didn’t want to feel so alone in the world, she got a job and conducted research that eventually led her to create genetically mutated human-plant hybrids that were birthed from monster spores. (All of this happened in Poison Ivy: Cycle of Life and Death, which is a little out of bounds but still totally relevant.) The result was the birth of Hazel and Rose, as well as the creation (and torture) of Thorn, who Poison Ivy would adopt into her little family. The girls have similar plant abilities to Ivy, but their accelerated growth rate ensures they’ve had very little time to master them.
The girls grew too quickly and actually ended up being more trouble than Poison Ivy ever intended them to be, so the three sisters got on a bus and haven’t been seen since. But they’ll certainly be back.
4. Bud and Lou
Yes, Harley Quinn’s beloved pet hyenas, Bud and Lou, make several appearances in the Gotham City Sirens series. They’re stuck in the Joker’s previous hideaway for awhile where they get sicked on Catwoman only to be shown who’s boss. Hyenas, Selina notes, are more similar to cats than most people realize.
Bud and Lou don’t serve much of a purpose other than being there when Harley needs them. They comfort her when she’s down and tear people limb from limb if necessary. But having a couple CGI hyenas traipsing around and curled up at Margot Robbie’s feet would be pretty great.
5. Ed Nigma (formerly: The Riddler)
The Riddler, the tongue-twisting, hint-dropping, green-clad classic Batman bad guy is on the outs with the darker side of Gotham in Sirens. He’s helping out Dick Grayson’s Batman, working as an informant of sorts when beckoned by the Bat, and is running his own private investigation firm. Ed seems to be one of the only people who’s figured out that the Batman isn’t being played by the same man anymore (but he does give him props for trying). Oh, and he’s dealing with some personal trauma.
The entire Gotham City Sirens series begins with Poison Ivy and Harley Quinn living in Ed’s townhouse. Ivy’s using her pheromone powers to keep him in a waking vegetative state of sorts, but once he’s freed, he goes on a rampage and uses his old question mark cane to smack the life out of Boneblaster, a third-rate criminal who destroyed his townhouse — this subsequently forces the Sirens to find refuge elsewhere.
6. The Batfamily: Bruce Wayne, Dick Grayson, Jason Todd, Tim Drake, and Damian Wayne
Harley Quinn, Catwoman, and Poison Ivy have always been, at their core, Batman baddies. Bruce Wayne’s situation may be a little complicated in Sirens, but Dick Grayson (the original Robin and subsequent Nightwing) has taken over the cowl and is now Gotham’s Batman-in-Chief. He’s backed by Damian Wayne, Bruce and Talia al Ghul’s lovechild as Robin, with mentions of Jason Todd’s fate as the Red Hood and Tim Drake’s Red Robin in the background.
The Batfamily is complicated, but seeing as Suicide Squad had a couple of Batman cameos, it would be endlessly fun to have at least a small mention of one of Bruce’s sidekicks in there. There’s never been a cinematic Batfamily film, and a cameo in Gotham City Sirens could be just the test drive a potential project needs.
7. Harley’s family
This one’s pretty brief, but even just a mention of Harley’s past would be fun. Gotham City Sirens #7 was the series’s holiday issue, which put Selina in the company of Dick Grayson, Ivy in the forests of South Africa, and Harley at home in Brooklyn. Her mother is overworked and underappreciated; her brother, Barry, is a bum who’s “in a band” and not working; and her niece and nephew are very supportive of Harley’s attempts at killing Batman. Oh, and her dad is in jail again. So, that’s fun!
8. The Joker
Jared Leto felt “tricked” by Warner Bros. after his Joker had a laughably short stint in Suicide Squad. His weird Joker will, undoubtedly, return in some form or another in Gotham City Sirens, since Harley’s origin story is so closely tied to the mad clown. However, unlike Suicide Squad, the Sirens comics are very much about Harley beginning to break away from Mr. J’s influence with the help of Ivy and Selina, so a big “screw you” from Harley seems inevitable.
“Anyone else would be happy to see [Harley] moving on and forming such a promising relationship,” Joker says in Gotham City Sirens #4 when he catches up with Harley Quinn making time with Hush disguised as Bruce Wayne (it’s complicated). “But I’m really a small, vindictive soul beneath this smile, and nothing would give me greater pleasure than to see her die in agony!” #HealthyRelationshipGoals
“Stay evil, doll face” solidified Deadshot and Harley Quinn’s friendship in Suicide Squad. While someone definitely needs to remind Will Smith that Deadshot is, in fact, a bad guy, there’s no doubt that Smith would be down to make a cameo appearance in the Sirens film. Their friendship was the surprising highlight of Suicide Squad, so seeing more Deadshot can only be a good thing, right?
And although Deadshot might not play a part in the Gotham City Sirens comics, there’s always room for more characters than necessary if Suicide Squad is to be taken as gospel.
10. Talia al Ghul
As far as onscreen appearances go, Talia al Ghul, the daughter of Ra’s al Ghul, has seen her fair share of action. She’s been featured in the CW’s Arrow and played a big part in Christopher Nolan’s The Dark Knight Rises, so another iteration of her as a rival to Catwoman isn’t too far out there. Catwoman and Talia al Ghul are the only women that Bruce Wayne ever truly loved, so, naturally, they’ve got some issues, and most of those stem from them both knowing Batman’s secret identity.
Talia teams up with a couple different people throughout the Sirens comics. Her presence is always appropriately foreboding, and, as always, she kicks ass.
Magic-wielding stage magician Zatanna is the other lady waiting in the wings (behind Talia al Ghul) who’s an obvious pick to appear alongside the main trio. Zatanna causes a lot of trouble for the Sirens, popping in and out of their secret lair and delivering cryptic messages. Somehow, a bathtub always seem to be involved.
At one point, Poison Ivy demonstrates her ability to communicate through plants by grabbing Zatanna in her own bathroom with the use of a bush and pushing her head under the water until she gets what she wants. So, while Zatanna doesn’t always have the most positive relationship with Harley, Selina, and Ivy, she certainly has an interesting one.
