New Justice League recruits
Justice League members come and Justice League members go, so the League expanded and added 42 new recruits to the League following some members resigning.

New Legion of Doom recruits
With The Justice League getting new recruits, it only makes for the Legion of Doom to get some new members as well. Some of the Legion of Doom members also include some of Batman's villains who have previously appeared in the DCAU before such as Man-Bat/Kirk Langstrom, Talia al Ghul, and Roxy Rocket/Roxanne Sutton.
