Teen Titans: The Judas Contract by her evil older jealous sister Blackfire who had staged a coup and forcibly took the throne. As she is no longer able to return to her world, the Titans offer her a home on Earth as one of them. In the present, Dick Grayson - now known as Nightwing - rejoins the Teen Titans to track down a terrorist cult led by Brother Blood, who plans on capturing the team to absorb each of their unique abilities with a machine that he has tested on Jericho; the latter is later executed by Brother Blood's lover and assistant; Mother Mayhem.
Alternative versions of Robin and his status as a crime-fighter with the Justice Society certainly reflected what had gone before. After the events of Flashpoint, Helena Wayne, daughter of Earth-2's Batman and Catwoman served as Robin and became the only partner that Batman had ever had. In this continuity, Bruce Wayne had never adopted Dick Grayson as his ward, so he never became Robin on Earth-2. However, he does appear later, married to Earth-2's Barbara Gordon, who never became Batgirl on Earth-2. The second Talon is shown in "Teen Titans" #38 (2006), the former sidekick of Owlman, created by Geoff Johns and Tony S.
