Katma Tui was a member of the Green Lantern Corps.


Katma Tui hailed from the planet Korugar, in the area of space designated as Sector 1417 by the Guardians of the Universe, beings from the planet Oa who oversaw and administrated the Green Lantern Corps. Korugar was also the home planet of the renegade former Green Lantern Sinestro, who used his Green Lantern powers to enslave his planet and rule over them as a tyrant, unbeknownst to his Guardian superiors. Tui eventually led a rebellion against Sinestro[1], and even testified against him before the Guardians, who imprisoned Sinestro in the Antimatter Universe, on the planet Qward. The Green Lantern Tomar-Re nominated Tui as Sinestro's replacement as guardian of Sector 1417, and Tui accepted.[2] The people of Korugar, however, came to view the Green Lantern symbol as one of oppression and pain and saw Tui as a monster for joining them. Tui was known among her people as "Katma Tui the Lost."[citation needed]

Green Lantern Corps

On her first mission, which occurred during her probationary period as a Lantern, Tui and Korugaran scientist Imi Kahn destroyed a giant space amoeba creature that threatened Korugar. Tui and Kahn fell in love, and Tui decided to leave the Corps, though Hal Jordan, the Green Lantern of Earth, used a ruse in order to persuade her not to.[3]

Tui went on to become an exemplary Green Lantern on a number of adventures, including a prison breakout on the Guardians' prison planet[4], her struggle against the telepathic influence of the alien Ffa'rzz the Mocker[5], the war against Krona, Nekron[6], the Weaponers of Qward[7], and the Anti-Green Lantern Corps[8], recruiting Rot Lop Fan to protect the Obsidian Deeps[9], the defeat of the extra-dimensional entity known as Maaldor, who had cut off the Lanterns from the Main Battery on Oa that powered them[10], etc.

John Stewart Katma Tui 01

Katma and John Stewart

When Hal Jordan resigned from the Corps for Carol Ferris, Tui was infuriated, given that Jordan had persuaded her to give up Imi Kahn for the Corps[11]. When John Stewart initially turned down the offer of replacing Jordan as Green Lantern of Earth, Tui, projecting her anger towards Jordan upon Stewart, dismissed him as a coward, which provoked Stewart into changing his mind and accepting the job[12]. Eventually, the Guardians assigned Katma to train John on Earth[13]. To avoid drawing attention and stay unnoticed, Katma changed her reddish skin to John's dark skin color.[14]. It didn't take long for both Green Lanterns to fall in love and start a romantic relationship, which even the Guardians approved.[15]

During the Crisis on Infinite Earths, Katma stayed to protect the Earth while John was recruited by the Monitor[16]. When the Crisis seemed to pass, she checked on her sector's situation, which, of course, also suffered the same upheaval as the rest of the universe. Fortunately, Katma was pleased to find Green Lantern Salakk of the neighboring sector 1418 protecting nearby planets on her jurisdiction.[17] When she returned to Earth, she joined John and the Green Lantern Corps on another mission to stop the newly-appointed Guy Gardner and his squad of villains attacking Qward's moon in the Antimatter Universe.[18]

Green Lantern Corps of Earth

Following the Crisis, the restriction for every Green Lantern to remain in one sector was lifted, allowing groups of Lanterns to settle in different planets. Katma went to Earth with John, where they settled along with an agglomeration of seven Green Lanterns in a Citadel in California.[19] During this time, her relationship with John flourished, and they married.[20] As part of the Green Lantern Corps of Earth, Katma helped her fellow Lanterns fight threats like Black Hand, Doctor Ub'x, and the rogue Lantern and fellow Korugaran, Sinestro.[21]


When the Green Lantern Corps was disbanded after the destruction of the Central Power Battery of Oa, Katma moved to an apartment with John on Earth. One day, the villain Star Sapphire sneaked into her house and murdered Katma in the kitchen, slicing her repeatedly, only to provoke Hal Jordan.[22]

John Stewart forged the Mosaic into a new society and eventually ascended to become the first mortal Guardian of the Universe, known as The Master Builder. As his reward for this new level of awareness, John was reunited with his late wife, Katma Tui. However, tragedy struck once again and Hal Jordan, possessed by Parallax, destroyed both the Guardians and the Central Power Battery, robbing John of his new-found powers and his resurrected wife.[23]

Blackest Night

Katma BL

Black Lantern Katma Tui

Katma Tui was among the many deceased Green Lanterns who were resurrected as Black Lanterns during the Blackest Night. After killing several Green Lanterns in Oa, she went to the recently resurrected Black Lantern planet, Xanshi. John Stewart was present at Xanshi's resurrection and went into the planet. There he found Katma Tui and the Green Lantern/Black Lantern hybrid, Driq. Driq encouraged John to destroy all the Black Lanterns, however, his attempts were futile and he had to escape to Earth. There, Black Lantern Katma Tui was definitively destroyed.

Katma Tui's long service as a Green Lantern was rewarded with an honorific place in the Crypts of the Green Lantern Corps[24].
