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 like 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 a crossover of the fictional universes of Earth-16 and 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
The pilot episode starts when Lex Luthor escapes from prison after he lost everything from the invasion of Darkseid, only later he was baited by Gorilla Grodd to be a "founding member" of his unstoppable Legion of Doom. When news about Grodd's Legion attracted the Justice League, they decided to expand their operations by enlisting new recruits across the globe, even creating a covert operation team called the Teen Titans. Now that the Justice League has expanded, they will do whatever it takes to stop the Legion and their own counter-operations team, the Terror Titans; even if it means helping other teams and confronting another New God invasion.

Design
The design is similar to the one on 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.
