Crisis on Infinite Earths
Kimiyo Hoshi, a brilliant and arrogant astronomer, was the head scientist of an observatory in Japan. She was overseeing a group of scientist studying the strange activity caused during the events of Crisis on Infinite Earths.
As the "Crisis" advanced toward Earth, Hoshi's affection with the phenomenon grew into an obsession while other scientist grew concerned for their safety. Disgusted by their mounting fear, Hoshi ordered an evacuation of the lab, leaving her to study the Crisis alone through her telescope.
Elsewhere, the Monitor, a celestial being linked to positive matter in the universe, notices his enemy, the Anti-Monitor, absorbing the positive-matter from a planet via his antimatter cloud. In an effort to tip the scales for the heroes of the positive universe, the Monitor sends an illuminating beam of energy from a star to Earth. That beam of star light stroke Hoshi in her observation lab, leaving her rendered unconscious. When she awoke, she had ability to control light and dawned the alias, Doctor Light. Hoshi is then asked by the Monitor to guard a vibration fork, needed to protect the Earth, from a machine deployed by the Anti-Monitor.
Starfire and Halo arrive at the scene to destroy the machine and Hoshi attempts to communicate with them However, being a native of Japan, Hoshi is unable speak English, so she attacks them instead. Superman would soon disrupt the fray, after using his multilingualism to communicate with her. The Japanese born hero Katana later takes over as translator for Hoshi until she is later granted the ability to understand English. Hoshi accompanies several heroes to the anti-matter universe to confront the Anti-Monitor. She and Superman discovered more machines that the villain had deployed to destroy the remaining Earths.The two of them were then attacked by the Anti-Monitor. The attack was thwarted after Supergirl arrived and sacrificed herself, allowing Hoshi to carry the unconscious Superman to safety. After witnessing Supergirl's sacrifice, Hoshi realize how arrogant she had previously been and decided to change her attitude.
Later, the assistant of the Monitor, Harbinger, summoned Hoshi for the final battle against the Anti-Matter. During the battle, she absorbs the light from the star that the Anti-Monitor was using to power his machines and blasts a gaping hole into his chest.

When "Crisis" was over, Kimiyo returned to her scientific studies and her family. She made few appearances as Dr. Light and soon was noticed by Maxwell Lord when he started to reorganize the new Justice League. Some weeks after being recruited, Dr. Hoshi is preparing to present the United Nation with her invention a solar storage units that could help undersea agricultural development, but her Justice League communicator keeps buzzing. When it finally stops, she leaves her office and is confronted by some men and a woman with guns. They quickly grab her and take her to the UN assembly room, where all the dignitaries are being held hostage by John Charles Collins. Hoshi alerts the Justice League via her communicator and waits. She is contacted by Martian Manhunter, who informs her help is there. She and the Justice League successfully takeout he terrorist and later rendezvous at the Secret Sanctuary.
Hoshi is informed that the man who gave her the Justice League communicator was not part of the team, but when Batman asked who had given it to her, couldn't remember. Before Batman can question Hoshi's farther, the League gets word that the Champions of Angor are attacking Israel. Batman asks Hoshi to come along and aide the League. When the League shows up to stop the Rocket Red Brigade, Hoshi uses her abilities to stop a them without hurting anyone, a feat that impressed Batman. Later back at the Secret Sanctuary, the League learns that Maxwell Lord was the one who gave Hoshi the communicator. Feeling like she has been played, she stormed out.
Hoshi gave up being Dr. Light for a time, devoting herself to her studies. Though her expertise with meta-humans led her to work with the Japanese embassy of Justice League International and she even become the leader of the European branch.
As a single mother with two young children, Dr. Light is only semi-active in the super-hero business, serving on both the Outsiders and Doom Patrol. A battle with the evil Doctor Light left Kimiyo powerless and close to death but with time she soon recovered.
She was later given a special power suit by the Shadow Cabinet, made from the remains of Arthur Light's battle armor, which helped stabilize her powers. With her powers stabilized, she was able to continue her super hero part time job, including aiding in the fight against the Secret Six and the Crime Syndicate of America
Following the disappearance of the Justice League, Kimiyo is recruited by Superman (Jon Kent) into a temporary League team. Kimiyo was present for the Battle at the Hall of Justice during Pariah's attack.
She accompanied a group of heroes to the House of Heroes, there she touched the Orrery of Worlds.
The Orrery revealed that her power, imbued by the Monitor, was a direct link to the Great Darkness' opposite, the Light of The Source. Taking on a new, more powerful form, she was able to purge Pariah's influence from Justice Incarnate. While unable to complete their intended mission, they resolved to return to the battlefield on Earth-0, now knowing that they could use Doctor Light's abilities to free those under Pariah's possession.

During Crisis on Infinite Earths Kimiyo was given a connection to "The Light of Creation" by The Monitor. Doctor Light has direct control over all forms of light sources without relying on equipment. She can manipulate light in any way, shape, or form. Kimiyo can absorb all forms of light, this ability extends to Kryptonians heat vision. She can illuminate a city or burn hole through steel. Channeling her powers, she can fly at great heights and speeds, although she has no form of invulnerability and is subject to windburn.
With her scientific research in solar power, she is quite adept at using light in a variety of ways. Such as; creating illusion, turning herself into light to phase through transparent materials, disperse radiation, scan electromagnetic spectrum, .
Hoshi, however, has never trained in hand-to-hand combat, preferring her powers to do the work for her. This has caused trouble for her in the past, and may limit her effectiveness in the future.
Dr. Light's abilities are entirely solar-powered, and she must be in proximity to a light source for her powers to be effective. Were she to be locked in a dark room her powers would quickly fade until she was powerless.
