[6] The character Ralph Dibny confronts and confirms the identity of Supernova but this information is not shared with the reader until issue #37 of the series where he is revealed to be Booster Gold.
With the assistance of Rip Hunter, he had faked his death and travelled back in time to become Supernova as part of a plan to stop Skeets, who was being controlled by Mister Mind.
Echoing Booster's origins, Daniel is a former high school football superstar, who has permanently injured his knee, ending his career.
Daniel fails to make good use of the new suit, however, and it is stolen by Booster Gold's father Jonar Carter, who becomes the third person to use the Supernova costume.
Parallel to those events, Daniel is left at home, where he meets Rose Levin, his future wife, who is a blogger/journalist hoping to make her fortune selling articles and photos of Booster Gold.
During his searches, he meets a Starro-probe, and thinking it harmless, tries to contain it in a mayonnaise jar, from which it escapes, taking control of Rip Hunter and the timestream.
[13] During the Blackest Night event, Ted Kord, reanimated as a Black Lantern, targets Daniel and Rose in order to lure out Booster.
[14] The Black Lantern Ted Kord would eventually be defeated by the combined efforts of Booster Gold, Skeets, Blue Beetle (Jaime Reyes), and Daniel himself as Supernova.
[19] The suit contains a copy of the white dwarf star size-changing belt used by the Atom, and an advanced laser system able to melt steel; Rip Hunter claims to have built it as resistant to all time ravages.
