Red Robin, (real name Time Drake) is a superhero vigilante, and a former member of the third generation Teen Titans. He is also a member of the Gotham Knights.

Biography
Tim Drake was adopted by Bruce Wayne after his parents were put into witness protection, following the kidnapping of his parents.

Before this, Tim had noticed Batman becoming more brutal towards his enemies, and tries convincing Dick Grayson to return to being Batman's sidekick, which he rejects.

Batman finally took in Tim following his adoption, training him for about a year before becoming Red Robin, out of respect for Jason Todd.

Founding the Gotham Knights
In mid-2016, Batman had created plans to found a team that would assist Azrael. These plans were never established, however, as Batman disappeared following the deaths of the Justice League's founders.

Tim had discovered these plans a month following, while attempting to locate Batman. Tim located Batwoman, whom Tim knew was assisting Batman in gathering this team.

Tim, along with Batwoman, decided to continue his plans. The team was successfully founded, and the Gotham Knights became the new defenders of Gotham.
