STARMAN

The most prominent member of the Justice Society in the pilot episode is Sylvester Pemberton, Starman and wielder of the Cosmic Staff before passing it on to his sidekick Pat as he succumbed to mortal wounds endured at the hands of the villainous Icicle. Pat later reveals that when Sylvester first became a superhero, he first used the moniker the Star-Spangled Kid. In the comics, the hero was introduced by Superman co-creator Jerry Siegel and Hal Sherman in 1941's Star Spangled Comics #1. Decades later, Sylvester would later become a member of the Justice Society and Infinity Inc.

WILDCAT

The Justice Society member actually seen in the pilot episode is the original Wildcat Ted Grant, gravely wounded after he is blasted out of the mansion where the Justice Society and Injustice Society are battling. The character was introduced by Batman co-creator Bill Finger and Irwin Hansen in 1942's Sensation Comics #1 as a world-class boxer who decided to fight crime as a superhero.  Ted was a co-founding member of the Justice Society and later retconned to be a member of the All-Star Squadron during the 1940s. After his legs were shattered during Crisis on Infinite Earths, Ted was temporarily paralyzed and passed the mantle of Wildcat to his goddaughter Yolanda Montez.

During Zero Hour, Rex was killed by the villain Extant. An incarnation of Rex from earlier in the timestream was revealed to have survived in a pocket dimension, offering his son Rick Tyler counsel as he took on the mantle of Hourman himself while knowing he would eventually have to face his death at the hands of the monster that killed Rex.

DOCTOR MID-NITE

Created by Charles Reizenstein and Stanley Josephs Aschmeier in 1941's All-American Comics #25, the original Doctor Mid-Nite was surgeon Charles McNider.

In Stargirl, Sandman is seen laying by the helmet of the Flash.
