Formation

The League is formed
After the Crisis on Infinite Earths, a new universe was formed with some aspects of Earth-1, Earth-38, and Black Lightning's Earth; the Earth-Prime. Waking up in the new Earth, the Paragons discovered the merge of their realities and, after defeating Sargon the Sorcerer and discovering the Anti-Monitor's survival, they banded together with the other heroes to finally defeat him and his Shadow Demons. Upon realizing that Anti-Monitor was too strong even for their combined powers, the heroes used Ray Palmer and Ryan Choi's knowledge to banish the villain, who had become a giant version of himself, into the Microverse.
After defeating the Anti-Monitor, the heroes went to an old S.T.A.R. Labs research facility. They look at Green Arrow's suit on display in front of a U.S. flag hanging there and Supergirl uses her heat vision to light a fire being contained in an arrowhead-shaped container. Flash then says the building is an old S.T.A.R. Labs research facility that nobody uses and no one knows it exists, so this is good for them to use as headquarters, and he takes off the cloth covering what looks to be a large round table with a crest that has a large star in its center. Each of the chairs has their own respective symbols associated with their suits. An empty 8th seat is left to honor Green Arrow's memory that has an arrowhead symbol on it. Gleek later escaped the facility.[3]
New Recruit
The S.T.A.R. Labs facility was later named the "Hall of Justice". Steel asked if he could join the team, but he never received a response.[4]
Injustice Protocols
The team later faced Felix Faust, which led them to create the Injustice Protocols; and a threat from an alternate timeline; Despero.[5]
Nora's Future
Original Multiverse
In Nora West-Allen's Future, the League tried to defeat the serial killer Cicada, but they failed.[1]
New Multiverse
The team later fought Magog in Nora's Future.[6]
