Nightstar (Mar'i Grayson) is a fictional character in DC Comics, the daughter of Starfire and Nightwing in the alternate universe of Kingdom Come.

She is joined by many other progeny of League members, including the daughters of Roy Harper, Garth, and Wally West, as well as the son of Donna Troy.

Batman has formed an alliance with Lex Luthor's Mankind Liberation Front to counter the Justice League.

Nightstar, who has been fighting Green Lantern, gasps in horror as this happens,[4] screams in agony as she cradles her father's bloodied face, and then flies him off to safety.

During the series and related events, Nightstar becomes part of a small super-team investigating reality disturbances in Planet Krypton, a restaurant owned by Booster Gold.

In The Kingdom: Nightstar, it is revealed that she has an interest in botany, a fear of death, and works with security at Alan Scott's space station The Green.

She also has superhuman strength, durability, and speed, and can absorb star energy to project in powerful bursts.
