With the release of the next DCEU film, Black Adam, just around the corner, fans are excited to see all the new characters featured in the film. Alongside Black Adam, the Justice Society of America is set to make its long-anticipated cinematic debut, which is one of the most influential superhero teams in comics history.

With longtime JSA members Hawkman, Doctor Fate, Atom Smasher, and Cyclone confirmed to appear in the film, fans of the team are clamoring for other longtime members to join up along the way. Though the JSA doesn't get the credit it deserves as the first-ever superhero team often enough, the group is made up of some of the most important characters in DC Comics history.

10 Alan Scott Is The Original Green Lantern

Though the Green Lantern franchise is synonymous with Hal Jordan and other members of the Green Lantern Corps, the first Green Lantern wasn't a magic user named Alan Scott. One of DC's oldest characters, Alan made his comic debut in All-American Comics #16 by Bill Finger and Martin Nodell in 1940.

Though the modern Green Lantern mythos is known primarily for the Green Lantern Corps, Alan's Green Lantern powers are magical, unlike the emotional spectrum-based powers of heroes like Hal Jordan and John Stewart. Alan is a longtime JSA veteran, appearing in nearly every iteration of the team.

9 Wildcat Is A Heavyweight Champion

The Justice Society's resident professional fighter, Wildcat is one of the best hand-to-hand fighters in DC. Though Wildcat wasn't a member of the original JSA roster, he joined the team in All-Star Comics #24 by Gardner Fox, Martin Naydel, and Kubert, only twenty-one issues after the team first formed.

A character with a wild side, Wildcat is known to occasionally let his emotions get the better of him, often resulting in serious violence. However, as an honored member of the JSA, Wildcat manages to keep himself on the side of justice.

8 Spectre Is The Spirit Of Vengeance

The embodiment of God's wrath, Spectre is one of the most powerful entities in DC. An original member of the JSA, Spectre first appeared with the team alongside all the other original members in All-Star Comics #3 by Gardner Fox and Everett E. Hibbard.

As a spirit tasked with punishing evil on behalf of a divine force, Spectre's form of justice is harsh, often leading to disagreements with JSA teammates. Though Spectre has spent most of the modern age of DC Comics as a solo character with no official affiliation to the JSA, he's played a role in numerous contemporary JSA stories, such as when he attacked Khandaq in the JSA Volume 1 storyline, "Black Vengeance."

7 Hourman Has Super Powers For One Hour A Day

One of the most underrated heroes in DC, Hourman made his comic debut in Adventure Comics #48 by Ken Fitch and Bernard Baily. Like Alan Scott, Hourman is an original member of the JSA and has stuck around for most of the team's history.

However, Hourman has achieved this as a legacy character. The original Hourman – Rex Tyler -– eventually passed the role down to his son, Rick Tyler. Although, unlike Rex, Rick took Hourman's powers to the next level when he gained the ability to see an hour into the future.

6 Stargirl Wields The Cosmic Staff

Originally going by the name Star-Spangled Kid, Stargirl was originally a member of the Junior Justice Society of America. Stargirl made her comic debut in DCU Heroes Secret Files and Origins #1 by Dan Curtis Johnson, Derec Aucoin, and Claude St. Aubin, but her creation is credited to Geoff Johns and Lee Moder.

Her days as a superhero came shortly after moving in with her stepfather, Patrick Dugan – the former sidekick of Sylvestor Pemberton, the original Star-Spangled Kid. According to The Direct, Stargirl was originally involved in the script for the Black Adam film but was later cut and replaced with Cyclone.

5 Doctor Mid-Nite Has An Owl Sidekick

One of the original members of the Justice Society, Doctor Mid-Nite is a brilliant surgeon turned superhero. First appearing in All-American Comics #25 by Bill Finger and Martin Nodell, Doctor Mid-Nite was blinded after a botched murder attempt by a gangster named Killer Maroni.

Later realizing he could still see in the dark, Mid-Nite created a special pair of goggles that allowed him to see during the day. On top of being a world-class inventor, Doctor Mid-Nite trains an owl named Hooty, who uses scout locations and even fights enemies alongside the JSA.

4 Mister Terrific Is One Of DC's Smartest Heroes

Though more than a few characters in DC Comics have used the title Mister Terrific, a vast majority of fans associate the name with Michael Holt, the third Mister Terrific. Michael Holt first appeared in Spectre Vol 3 #34 by John Ostrander and Tom Mandrake.

Officially ranked the third most intelligent person in DC, Terrific is a prolific inventor, which led to his creation of T Spheres, which are floating robotic spheres with numerous unique applications. Terrific also uses his brilliance for strategy – mainly when he served as the JSA's chairman, effectively leading their missions.

3 Jakeem Thunder Controls Yz

A teenager from Keystone City, Jakeem Thunder is the second companion of Yz, a powerful genie-like entity capable of granting wishes to its user. A djinn from the 5th Dimension, Yz was originally paired with Johnny Thunder until the latter decided to retire.

Jakeem first appeared in The Flash Vol 2 #134 by Mark Millar, Grant Morrison, Paul Ryan, and John Nyberg, in which he received an ink pen containing Yz from longtime JSA member Jay Garrick. Learning the true nature of the Yz, Jakeem joined forces with the Justice Society and the Justice League when evil members of Yz's species came to Earth.

2 Power Girl Is Superman's Cousin

Supergirl's Earth-2 counterpart, Power Girl is the cousin of Kal-L, Earth-2's Superman. First appearing in All-Star Comics #58 by Gerry Conway, Ric Estrada, and Wally Wood, Power Girl flew down out of seemingly nowhere to save The Flash and Wildcat from falling into a volcano. Six issues later, she officially joined the JSA on an adventure through time to ancient Camelot.

Following the events of The Crisis On Infinite Earths, Power Girl's background was altered completely, but she still ended up joining the JSA when Black Canary recommended her as a replacement. Though Power Girl has served on numerous other important hero teams like Infinity Inc. and the Justice League, she's always remained a member of the JSA at her core.

1 Jay Garrick Is The Original Flash

Arguably the most famous member of the Justice Society of America, Jay Garrick is the original Flash, first appearing in Flash Comics #1 by Gardner Fox and Harry Lampert. Given the ability to superspeed after consuming hard water gas, Jay's powers don't derive from the speed force, unlike the powers of Barry Allen and Wally West.

Another brilliant scientist, like Alan Scott and Hourman, Jay Garrick has appeared with most iterations of the JSA, serving from its inception into the modern age. Due to his many years of service with the team and his nearly unwavering optimism, Jay often acts as a mentor for its new, younger members.
