Niko and Lev's Crew - Batman & Robin

A small-time gang of Russian drug dealers and people smugglers, they wanted to make a name for themselves by cornering Gotham's overcrowded drug market. 

They partnered with Le Cirque D'étrange, helping them to spread their virulent identity-destroying compound throughout the city. They would often test the product on the young women they trafficked, forcing them into sex work. 

After Batman and Robin disrupted one of their deals, Niko and Levi planned to flee Gotham until the heat died down. However, Professor Pyg, Le Cirque D'étrange's leader, saw this as a betrayal and took revenge against them. 

Their operation was shut down by Batman and Robin.

Masks of Evil - Batman & Robin

A crime-thriller novel written by the late Oberon Sexton. 

Clara Saberton - Batman: Arkham Knight

The personal secretary of Bruce Wayne, Clara Saberton, remained behind in Gotham during Scarecrow's Halloween siege. In the relative safety of Wayne Tower's top floor, she continued working for Wayne and Lucius Fox. 

She was deceived by Thomas Elliot, aka Hush (nee the Identity Thief), who was impersonating Bruce Wayne. Mistaking him for her real employer, she was surprised to see him, believing he had evacuated the city hours earlier.

Minutes later, after hearing a disturbance coming from Wayne’s office, Clara went to investigate—only to be shot at by “her boss,” who had taken Fox hostage.

Convinced that Bruce Wayne had gone insane, she was relieved by Batman's appearance, begging the vigilante to save Fox. 

With the building still under lockdown, Clara fled to the lower floors, reasoning they were still far safer than Gotham's besieged streets. 

Officer J.T. Wicker - Batman: Arkham Knight

A corrupt officer in the GCPD, JT Wicker, has been working as a mole and informant for the Riddler for years, helping Nigma stay one step ahead of the police and feeding him inside information that he could use against them. Their partnership started ten years ago, when Nigma, then going by the name Eddie Nashton, infiltrated the GCPD as the head of the Cyber Crimes Unit. 

In the runup to Halloween, and Riddler's latest scheme against Batman, he planted several of Nigma's trophies throught GCPD headquarters.

When Batman discovered Wicker’s ties to the Riddler, he confronted the officer, demanding he reveal everything he knew about Nigma’s plans. Unable to convince his fellow officers that Batman was lying, Wicker confessed, shocking and disgusting his colleagues. 

He spent the rest of the evening locked in a holding cell. Wicker attempted to garner sympathy from his colleagues, claiming he was a triple agent and acting on Gordon's behalf, though no one believed him. 

Realising he had no allies, he dropped his act, lashing out at Batman. He called out Batman's hypocracy and brutal methods, blaming him for Riddler's mental breakdown and obsession with humiliating, unmasking and killing the vigilante. 

"The Starfish Freak" - Batman: Arkham Knight

Known as "The Starfish Freak," he was once a construction worker at Seagate Amusement Park who became possessed by one of Starro the Conqueror’s Star-Spawn. After turning violent and attacking his fellow workers, he was eventually subdued, and both he and Starro were imprisoned.

At Jack White’s suggestion, Edward Burke planned to feature them as the main attractions of the park’s freak show, emphasising the man’s loss of bodily autonomy and marketing him as “more beast than man.”

After Jack White and Dr. Harleen Quinzel persuaded Burke to take his own life, shortly after he signed over the deed to Seagate, some believe that the Starfish Freak was stored away alongside Starro. 

However, most assume he was killed when the Joker halted all construction plans and turned the park into his latest hideout.

Feral - Star Wars: The Clone Wars

The younger brother of Savage Opress and Maul, Feral, was a Zabrak from the planet Dathomir and the son of Mother Talzin.

He was raised alongside his brothers, trained in combat under Brother Viscus, and eventually joined the Nightbrothers, pledging loyalty to his mother and the Nightsisters.

In 20 BBY, during the Clone Wars, Feral was among those selected by Asajj Ventress to compete in a brutal selection process to choose a champion for her revenge campaign against her former master, Darth Tyranus—aka Count Dooku.

Feral survived the gruelling trials, fighting side by side with Savage, until they were the last two standing. Despite surviving the three initial tests, he was deemed unworthy of becoming Ventress's apprentice. 

Rather than killing him outright, he was taken prisoner by the Nightsisters to serve as the ultimate test.

After Savage was chosen as Ventress’ champion, both she and Talzin ordered him to kill Feral to prove his loyalty. 

His desperate pleas for mercy went unheard as Savage snapped his neck.

Officer Krane - Star Wars: Jedi Fallen Order

An Imperial officer serving the Galactic Empire, Officer Krane, was "assigned" to oversee Project Auger—a mining operation aimed at excavating ancient artefacts buried on the planet Zeffo.

Believing the previous project leader lacked the necessary leadership and drive, Krane orchestrated a mutiny and seized full control of the operation.

Ambitious and eager to win Emperor Palpatine’s favour, Krane became increasingly reckless. She disregarded warnings from her subordinates and dismissed many discovered relics as worthless trinkets, unworthy of excavation.

After one of her troopers uncovered a valuable relic within the Ice Caves, Krane attempted to confiscate and smuggle it off the planet, believing that presenting it to the Emperor would result in personal rewards and a promotion. As she attempted to keep the artefact concealed from the rest of her team, tremors caused by the mining destabilised the cave, causing a collapse of ice and rock that buried her alive.

In 14 BBY, during a covert mission to Zeffo to help rebuild the Jedi Order, Cal Kestis discovered Krane’s remains. Using his ability to access Force echoes, he experienced her final moments and witnessed the reckless ambition that led to her demise.
