Justice League: Brave and the Bold

This is a DC Animated Series based on the entire DC Universe and featuring a wide array of superheroes from the same universe as well. The animation is a continuation of the series Young Justice, but has a voice cast of not only this series but from Justice League Unlimited as well. The main setting is the fictional universe of Earth-16 but has similarities to DCAU, during a time period when superheroes are a great phenomenon. The series follows the lives of the expanded Justice League and their young counterparts, the Teen Titans.

Plot
After the Invasion of Darkseid, the Justice League decided to expand their operations and prevent another invasion by enlisting new recruits across the globe (along with an extensive support staff), building a new Watchtower and hi-speed Javelins, expanding their organziation and their covert operation team of young superheroes, which they renamed the Teen Titans. But when Lex Luthor escapes from prison after he lost everything from the invasion of Darkseid, he was later baited by Gorilla Grodd to be a "leading member" of his unstoppable Legion of Doom. Now that the Justice League has grown into an army, they will do whatever it takes to stop the Legion and their own counter-operations team, the Terror Titans; even if it means helping the Earth and confronting another New God invasion.

Design
The design is similar to Young Justice, but it is intended to create costumes based in reality to match the tone of the series while keeping consistent with traditional DC Universe continuity.
