While the core cast of Suicide Squad: Kill the Justice League is already set, there are several other beloved villains in the Squad that could make an appearance in the game. Throughout the years, and more notably in recent years, various iterations of the Suicide Squad have been seen in different forms of media. These squads all have their own members, missions, and personalities. Kill the Justice League has already shown that the playable cast is made up of four of the most popular members, including Harley Quinn and Deadshot, but other members from comics and movies could make appearances as well.

Suicide Squad: Kill the Justice League will see Captain Boomerang, King Shark, Deadshot, and Harley Quinn hunting down the Justice League after KTJL's true villain, Brainiac, places Earth's heroes under his control. The Flash and Superman are two of the heroes shown so far, though others are sure to be included in the full game. Kill the Justice League isn't going to launch until 2023, so there is also plenty of time for Rocksteady and WB to show off other heroes the Squad will have to go up against.

Though the core four members of Suicide Squad: Kill the Justice League's version of Task Force X will likely remain the same, that doesn't mean other members of the team can't show up. With so many different iterations in comics, television, and movies throughout the years, there are plenty of villains to choose from. However, here are some of the members who deserve cameos in Suicide Squad: KTJL the most.

Polka-Dot Man Should Be In Suicide Squad: Kill The Justice League

Even though like King Shark, they would differ from James Gunn's 2021 movie The Suicide Squad, Polka-Dot Man would be a fantastic villain to include as a cameo in Suicide Squad: Kill the Justice League. In his portrayal in the latest Suicide Squad movie, Polka-Dot Man had an entertaining arc, although it was ended somewhat abruptly by Starro The Conqueror. However, Polka-Dot Man could get another moment to shine in the upcoming Suicide Squad game.

Unfortunately, Polka-Dot Man would potentially have a similar end to his movie counterpart in Kill the Justice League. Especially with the game's playable cast likely capping at the four members shown so far, Polka-Dot Man would possibly be fodder to be killed by a member of the Justice League. However, a quick death would still be a great punchline for DC fans, and could help drive home that in a Suicide Squad: KTJL may destroy the Arkhamverse if it's as lethal as its title suggests.

Cheetah Could Tie The Upcoming Wonder Woman Game To The Arkhamverse

A member of the Suicide Squad in both DC comics and animated movies, Cheetah would be an interesting member to cameo in Suicide Squad: Kill the Justice League. Her connection to Wonder Woman would make for an easy way to include her as a cameo in the game. The game could even show a fight between her and Diana, to show that Wonder Woman is no longer holding anything back, with Dinah seemingly the one Justice League member not under Brainiac's control.

Alternatively, Cheetah could be a post-credits cameo stinger to connect Monolith's Wonder Woman game to the Arkhamverse. The upcoming Wonder Woman game likely isn't in Rocksteady's Arkhamverse, as the game isn't being developed by Rocksteady. If WB did want to connect the two and try their hand at a video game multiverse after the bumps the DCEU has experienced, including Cheetah as a central villain in Wonder Woman's solo outing after a cameo in Suicide Squad: Kill the Justice League would be a good way to do it.

Suicide Squad: Kill The Justice League - Ambush Bug Would Be A Fun Gag

A lesser-known DC character, Ambush Bug could be an interesting cameo addition to the cast of Suicide Squad: Kill the Justice League. Introduced in 1982, Ambush Bug is an anti-hero/villain named Irvin Schwab. Clothing sent from the planet Schwab was intercepted by a radioactive space spider, giving the wearer of the clothing power of teleportation.

Ambush Bug isn't as prolific a character compared to other Suicide Squad members, similar to Peacemaker (who could lead a perfect Rocksteady game). However, this makes Ambush Bug a perfect candidate to be developed separately in a small role. With his powers of teleportation, perhaps Ambush Bug could even serve as a fast travel conduit for the team, taking team members to their next missions.

Suicide Squad: KTJL Could Bring Back Arkham's Killer Croc

Unlike the other members in this list, Killer Croc already has an existing version in Rocksteady's Arkhamverse. Having last appeared in Batman: Arkham Knight's Season of Infamy DLC, it's not out of the realm of possibility that he could make a return in Suicide Squad: Kill the Justice League. In addition to Harley being one of the Squad's core members, Killer Croc could provide an additional connection to Batman: Arkham, as well as possibly being a squad member for a short time.

Killer Croc could also be a great way to show how threatening the newly-evil Justice League really is. Although he wouldn't be playable like he was planned to be as a villain in Batman: Arkham Origins' open-world, Croc could be involved in a small role for Suicide Squad: Kill the Justice League. Whether he serves as temporary muscle or a show of strength, Croc would be a welcome Arkham returnee to Suicide Squad.

Atom Smasher Could Tie Black Adam Into Suicide Squad: KTJL

A member who is poised to become much more popular, Atom Smasher could be an interesting cameo addition to Suicide Squad: Kill the Justice League. Able to shift his atoms, Albert Rothstein can use his powers to grow to a larger size and give him super strength. Although a hero, Atom Smasher is one of several superheroes to have served in the Suicide Squad. In addition, he may gain more popularity from an appearance in the upcoming Black Adam film, where he'll be played by Noah Centineo.

Atom Smasher's powers of growth would make him a perfect member to show the scale of the Suicide Squad's conflict in Kill the Justice League. Suicide Squad: KTJL is hiding more than Brainiac, surely, and Atom Smasher could be a great fit to take on larger threats. There's no better Suicide Squad member to show a large-scale event better than Atom Smasher.

The core cast of the Suicide Squad in Suicide Squad: KTJL is incredibly strong, but additional cameos from these members and more would go a long way to making its cast feel like a complete squad. They can also serve other purposes, like tying into other games or enabling in-game functions like fast travel. Either way, it would make sense for Suicide Squad: Kill the Justice League to have some surprise cameos in store when it drops in 2023.
