Real Name: Yuriko OyamaWhen she first left Japan (before her transformation) she used a katana, with which she was quite skilled. To truly accomplish her mission, Yuriko allowed Spiral and her Body Shoppe to transform her into a cyborg. She possesses bionic limbs and senses, telescoping arms, and lethal claws, among other enhancements. For much of her career afterwards she has operated with Pierce's Reavers, but she also works alone. However, when Logan lost his original metal bones, her life's mission was been upset, to say the least.
Recently, Deathstrike was attacked and severely wounded by Sentinels. She fled to the X-Men, who agreed to help her, if not trust her. They ended up being captured by Stryfe, who revealed that Deathstrike's maker was the same as the designer of the Prime Sentinels. Stryfe needed the command codes in Deathstrike's system in order to fully activate the Primes. The X-Men managed to defeat Stryfe, however, and Deathstrike seemed to have learned something about how to release her vengeance during the encounter. This event raised certain questions about Deathstrike, who was said to have an adamantium skeleton and to have been built by a human, not by Spiral. The truth about these revelations in unknown. Although she didn't try to kill Wolverine even once during this encounter, Deathstrike soon returned to her murderous ways, accepting employment from Sabretooth and hunting down Wolverine's closest friends and family. In particular, she was responsible for the apparent crippling of Yukio and the abduction of Amiko, Logan's foster daughter.
Later, Deathstrike effected a vicious breakout of Reverend Stryker from a prison transfer plane, and helped him capture Shadowcat. Then her cybernetics were compromised by the techno-viral efforts of Reverend Paul and she turned on Stryker's men, killing them all, and nearly getting Stryker as well. She encountered the X-Men who had come to investigate, and appeared to kill Wolverine before she was subdued by Cannonball. Wolverine revealed that he faked death so that Deathstrike would move on, since in that state she was uncontrollable. Presumably she returned to normal when Paul went into suspended animation.
