The Injustice League was a team of meteor freaks and antagonistic faction in the CW Television series Smallville.
Their main objective was to find and destroy Doomsday to protect the Traveler.
They were portrayed by Jessica Parker Kennedy, Brendan Fletcher, who also played Bill Williamson in the Rampage film trilogy and Stanley Dover in Arrow, Anna Mae Routledge, Jae Lee, and Anna Williams.
When Tess Mercer took control of LuthorCorp after Lex Luthor vanished, she shut down several facilities that were related to Level 33.1 including one in Montana called Black Creek but many meteor freaks had escaped. She decided to find and recruit them to form a team of heroes to fight for the human race.
Mercer had them trained to become a team, to look out for each other.
Tess first tried to recruit Bette Sans Souci who had escaped the Black Creek facility, but instead she blew up the bus with Tess was on. After Bette was captured, Tess and her team intercepted the prison transport and once again offered her to be part of a team with other special people like her. Bette agreed to join the group so she wouldn't go to Belle Reve.
When a serial killer began killing people in Metropolis, a copycat decided to join in on the action and killed several meteor infected people. It was revealed that the imposter was Randy Klein who was stopped by Clark Kent and arrested by the police. Tess had sent her assistant Eva Greer to recruit Randy to join their newly formed team otherwise she'd blackmail him by providing evidence that he wasn't the real killer.
Overtime the team recruited Leslie Willis, Rudy Jones and Nathaniel Tyron who went on their first field mission to hunt down Doomsday and goad Clark Kent into battling the monster. Eva Greer posed as Chloe Sullivan and ran through the woods pretending someone was after her while she screamed for Clark's help.
Then, as she stands on a road frozen in the lights of an oncoming truck, Clark super speeds in and saves her before she gets hit. Unknown to Clark, they were being watched by Livewire, Plastique, Parasite and Neutron.
Under no circumstances were they to confront Doomsday themselves. But, Livewire and Neutron found themselves confronted by the beast, while the other members were elsewhere. Neutron died in the ensuing battle and Livewire announced that she was leaving the team. This prompted Parasite to remove her abilities, while a small explosive in her head was activated, killing her.
Upon discovering the latter, Mirror informed Parasite and Plastique about her suspicions that Mercer had been the one behind it, but they rejected Mirror's claims. Tess was monitoring Chloe's call to Plastique. At the Isis Foundation, "Chloe" admits that she knew Livewire, aka Leslie Willis, and discovered she was part of a team assembled by Tess.
After Mirror was killed the same way as Livewire, Plastique and Parasite came to believe her and took Mercer hostage. Plastique vows vengeance on Tess, but Clark tries to stop her. Parasite then emerges and grabs Clark. He drains Clark's powers but is knocked back by the intensity. He remarks that he thought Clark's only power was super speed. Parasite is about to attack Clark again, but Plastique says that Clark can do nothing to stop them.
He whisks Plastique away as a powerless Clark looks on. Parasite tortures her, but Tess claims Eva and Livewire betrayed him and Plastique. Plastique wants the Black Creek files, so they can form their own league. Clark then comes in and warns them away. Plastique knocks Tess out while Parasite moves in.
Clark tries to get through to Plastique, but is unsuccessful as she tells him she'd rather be with the bad guys. This led to a confrontation between them, Clark and Green Arrow. Suddenly, Oliver shoots Plastique through the shoulder, swings in, and uses Lex's kryptonite ring to fell Parasite.
He then viciously beats Parasite, but Clark calms him down and gets him to stop. Clark tells Parasite he must give back Clark's powers to stop the pain. Parasite does so, and passes out from the strain. Clark turns to see Oliver carrying Tess out. Parasite and Plastique were taken into custody.
