"The Flying Graysons were present the night of the Gotham City Charity Circus where all but Dick perished in an attempt to stop a bomb that was planted by Two-Face. Due to Dick's entire family being killed, he was welcomed under the legal custody of Bruce Wayne, who felt guilty for not being able to save Dick's family. Batman was able to avenge Dick's family by tricking Two-Face into falling to a watery grave several feet above a large containment of water and sharp stalagmites, which greatly satisfied Dick. Dick went on and became Batman's sidekick, and adopted the alias, Robin."@en . . . . .
