Valentina Vostok of the Soviet Air Force stole an experimental Russian fighter plane in order to defect to the United States. The plane malfunctioned en route and she crash-landed at the spot where the original Doom Patrol had apparently perished and was fused with the negative energy being which formerly inhabited the body of the Patrol's Negative Man. However, instead of being able to send it out from her body under her control, Vostok gained the ability to transform herself into such a being. Years later, it was revealed by Doom Patrol villain the Brain that Niles Caulder, founder of the Doom Patrol, manipulated Valentina's transformation into a superhero in order to create a replacement for presumed dead Negative Man. Assuming the name Negative Woman, Valentina defected to the United States and became a member of the second incarnation of Doom Patrol for several years. Valentina became romantically involved with teammate Joshua Clay, aka Tempest, but broke off the relationship due to the nature of her powers changing to match that of her predecessor: her body became permanently radioactive, requiring her to constantly wear radiation-blocking bandages over all of her body, and the radio-energy being would emerge from her under her mental command. Ultimately, when Negative Man was found alive and rescued by the new Doom Patrol, the negative energy abandoned Valentina and was returned to Larry Trainor. Though she was initially furious at having lost her power and being replaced by Negative Man, his ultimate rejection of the power allowed for Valentina to leave the Doom Patrol on good terms, unaware of the fact that the negative energy being would ultimately return and claim Trainor again, turning him into Rebis. Valentina would go on to work for the American secret services, being involved in a number of US government departments including serving for a time as head of the Agency and working for the original incarnation of Checkmate.
Vostok was later named White Queen of the current incarnation of Checkmate, replacing Amanda Waller.
''Final Crisis''
A Negative Woman was among those in the Blüdhaven Strike Force in Final Crisis #4 sent by Checkmate. Included are Count Vertigo and Atomic Knights. Vostok is seen under Darkseid's control in Final Crisis: Resist.
''Blackest Night''
Valentina was apparently killed during the events of Final Crisis, as her corpse is reanimated as a member of the undead Black Lantern Corps during the Doom Patrol series' Blackest Night tie-in storyline. She attacks Larry Trainor, using a corrupted version of the Negative creature. Trainor absorbs both Negative Creatures, taking control and sending both of them into Valentina. This causes her body to overload and explode, destroying the black ring.
In The New 52 reboot, Negative Woman first appears in Justice League vol.2 #24 in a camera being watched by Grid, and is seen again in Justice League vol.2 #27 where she was seemingly killed off by Johnny Quick and Atomica.
Powers and abilities
Valentina formerly possessed a radioactive "soul-self", and was capable of flight and intangibility, and could generate minor explosions upon contact with positive energy. She no longer possesses these abilities.
In other media
Live action
Valentina Vostok appears in the Legends of Tomorrowseason one episodes, "White Knights" and "Fail-Safe", portrayed by Stephanie Corneliussen. In 1986, Vostok is a Soviet scientist employed by Vandal Savage to develop a composite "nuclear man" after the latter witnessed Firestorm a decade previously. Savage and Vostok capture half of Firestorm, Dr. Martin Stein, and torture his allies to force him to divulge the Firestorm matrix's secrets. After Vostok discovers Stein has part of it, she forces him to merge with her despite his warnings of requiring a "quantum splicer" to stabilize the fusion process. Stein's partner, Jefferson Jackson, encourages him to fight Vostok's control, giving Jackson time to break Stein free and escape with him while Vostok loses control of the matrix and releases the energy in a nuclear explosion, though her fate following this is unknown.
Valentina Vostok appears in the Doom Patrol episode "Space Patrol", portrayed by Mariana Klaveno. This incarnation is a member of a three-person research team sent into space by the Chief in 1955 to find a source of time-dilating power. Her teammates Zip and Spec perish during the mission, but Vostok makes contact with the source, which she discovers is a negative energy entity that inhabits her body. Over 60 years later, the now ageless Valentina returns to Earth so she can use the planet's atmosphere to kill alien spores that reanimated Zip and Spec's bodies. This leads to a personal conversation between herself and Larry Trainor over their experiences with their negative energy entities and how it impacted their lives. She invites him to join her in returning to space once she finishes severing her ties to Earth, but Larry declines in favor of repairing his relationship with his family.
