Nightwing
For several years, Nightwing leads various incarnations of the Titans and becomes the most respected former sidekick in the DC Universe. However, in the "" crossover, a rogue Superman android kills Lilith and Troia, an event that tears apart both Young Justice and the Titans. At Troia's funeral, Dick declares he is tired of seeing friends die and disbands the team, officially ending the Titans. A few months later, Arsenal persuades Nightwing to join a new pro-active crime-fighting team: the Outsiders, who would hunt villains, acting as co-workers rather than an extended family. He reluctantly accepts.
