Justice League

The Justice League is a team of heroes working together to keep both Metropolis and Earth safe. It has been headed at different times by Green Arrow, Watchtower and finally Superman.

Members

 * Boyscoutt, the Blur, Superman: Originally not a full time member, he has become more accustomed to working within the team and has become the official leader. Originally known as Boy Scout, then known by the media term Red-Blue Blur and later simply by The Blur, he became Superman after revealing himself to the Earth although Oliver tells the team to still refer to Clark by his "Boy Scout" code name. He has been a part-time member since Season Six, but has been a full time member since Season Eight, and the leader in 9.
 * Green Arrow: The League's founder and former leader. He provides funding for the League using his vast wealth, supplying tech to Watchtower to keep an eye on the Earth. He lacks extraterrestrial capabilities and is the only member to have revealed his secret identity to the Earth.
 * Impulse: Being a founding Member, Bart Allen (aka Impulse, though he did not chose the name himself), he is the fastest one of the team, and was a part of the very 1st mission to take down Level 33.1, and joined the team on the mission of killing Doomsday. He seemingly died while facing the Black Flash.
 * Aquaman: Arthur was recruited by Oliver Queen when he was in Japan where Oliver saved him from "ending up in a thousand tuna cans". With Bart Allen and Victor Stone, they hope to bring down Lex's Level 33.1. He also joined the team to rescue Clark, and appeared for Hawkman's funeral.
 * Cyborg: One year after his escape from Lex Luthor, Victor and his girlfriend Katherine broke up. Depressed and ready to give up, he was living on the streets when he met Oliver Queen. Oliver offered him food and shelter and, according to Victor, gave him "a reason to go on." Oliver recruited Victor for his fledgling hero team. Victor's technology was upgraded by Queen Industries so he could hack into schematics and security data.
 * Watchtower: Chloe Sullivan, as Watchtower, was the team's eyes and ears around Metropolis and the rest of the Earth, providing information and access to each member and was considered the unofficial leader coordinating each League member with a mission. She recently returned to the team after a long absence and was revealed to be in control of the Suicide Squad. In Fortune she temporarily resigned from her role as Watchtower, but rejoined the team in Finale, Part 2 after Tess's disappearance. She operates as Watchtower from three separate facilities in The Watchtower, S.T.A.R. Labs, as well as another base in Star City.
 * Martian Manhunter: Joined the team after permanently basing himself in Metropolis as a detective, John regained his powers and became an integral part of the team, providing cover with the police. He also has a prison on Mars where he holds threats no regular prison can hold such as Curtis Knox and a parallel version of Bruce Wayne.
 * Black Canary: Originally a gun for hire attacking the League, she joined the cause after being exposed to the truth and is considered an important player in the League. She joined them on the mission's of saving Clark and killing Doomsday.
 * Zatana: Zatanna is revealed to be a member in Icarus. She has helped out on occasions. She also mentioned to Oliver that if he ran into any dark magic, he can give her a call and she would be willing to help.
 * Booster Gold: After Clark helped Booster realize what it truly means to be a hero, he repaid the favor by upgrading the systems in Watchtower based on his and Skeets' knowledge of technology from the future.
 * Stargirl: The youngest member of the team, step-daughter of Pat Dugan and Sylvester Pemberton's successor, for a short time she worked with the reformed Justice Society of America, but switched teams after attempting to recruit its former members. Eventually, she helps Jay Garrick recruit members for his team, before working alongside them in the Crisis.
 * Hawkman: Hawkman was the leader of the Justice Society and apparently a member of the Justice League. He sacrificed his life to save Lois Lane in a battle with Slade Wilson.
 * Dr. Emil Hamilton: A staff physician at Metropolis General Hospital, Emil is also on Oliver Queen's payroll, after Queen was poisoned and realized having an on-staff medic would be beneficial to their team efforts. He was called in when Detective John Jones was shot in the line of duty and needed 'extra care' due to his true alien nature. He is the third most frequently featured member and has been a part of the team since Season 8.

Oliver, who was infected with the darkness, had a super brawl with Clark which interrupted Clark and Lois's wedding. After Clark freed Oliver of his corruption, Apokolips came over Earth and caused an Eclipse. With Watchtower malfunctioning, Chloe set off for her database in Star City. Lois stowed away onto Air Force One, to stop the Government from launching a nuke at Apokolips, which would only cause millions of human casualties from Nuclear debris, which the Government was well aware of. Tess was able to kill Lionel, who then sold his soul to Darkseid in exchange for Lex's rebirth. Lex later killed Tess at LuthorCorp, but not before she erased his memories, preventing him from causing Clark harm.
