Doctor Light appeared in the sixth season of the television series The Flash, portrayed by Emmie Nagata.

Doctor Light first appeared in Crisis on Infinite Earths #4 and was created by Marv Wolfman and George Pérez.

[3] Kimiyo Tazu Hoshi, a brilliant but overly-driven scientist,[4] was the supervising astronomer at an observatory in Japan during Crisis on Infinite Earths.

An article discussing the destruction of Star City (and, by extension, Kimiyo's loss of power) appeared at the 52 website, which is designed to complement the weekly comic series.

She does, however, appear in Birds of Prey #113 (January 2008), assisting Oracle by scanning the electromagnetic spectrum for any evidence that might lead her to the parties responsible for an influx of hi-tech weaponry being smuggled into Metropolis.

Doctor Light is only occasionally active in the superhero community because she is a single mother with two children: Imako, her daughter, and Yasu, her son.

After briefly talking with the heroes, she becomes enraged and attacks them after coming to believe they have harmed her children, only to be quickly neutralized and captured.

[7] Hardware uses Arthur Light's powers to restore those of Kimiyo, allowing her to quickly defeat Shadow Thief and Starbreaker.

[11] Kimiyo briefly appears during the War of the Supermen, where she and the rest of the JLA attempt to repel General Zod's invasion.
