Mariko Yashida

History

The daughter of Shingen Harada, Mariko's the sister of Silver Samurai and cousin to Sunfire and Sunpyre.

Mariko was the head of a Yakuza family, inheriting the position from her father. She was Wolverine's fiancée until Mastermind interfered. Mariko was poisoned by Matsuo Tsurayaba; rather than face a painful death, she begged Wolverine to kill her. Wolverine went after Matsu'o and exacted his revenge by annually removing a body part on the anniversary of Mariko's death. 

Alternate Versions

Earth-295:  Age of Apocalypse

Mariko was first seen as a young girl in Japan, sabotaging a video arcade, much to the anger of the Yakuza. Thanks to the interference of Wolverine, she was not harmed. Before he left, he told her to go back to school and make something of her life. Mariko obviously listened, as she worked her way onto the Human High Council along with Captain Britain, Emma Frost, Bolivar Trask, and Moira MacTaggert. While the Council considered stopping Apocalypse with nuclear weapons, Mariko was the sole holdout. She expressed her dislike for a nuclear solution to Weapon X, as well as her distrust for Brian Braddock, which proved to be well-founded. After the fall of Apocalypse, Mariko moved back to Japan to rebuild her homeland.

Mariko was a human and did not have any mutant powers. 

Earth-2109:  Exiles

Exiles Sunfire

On a mission where the Exiles were sent to foil a bank robbery, which took fifteen minutes, they were then given the whole week off to relax. Blink begged Mariko to take Morph away for a day, as the others wished to go to a beach nude and were worried Morph would spoil the mood, and she eventually agreed and tempted Morph by offering to take him lingerie shopping with her. During the course of the day the two swapped stories and although Morph found out why she had originally offered to take him with her, he forgave her. The two enjoyed a meal together and Mariko explained how her parents had disowned her when her mutant powers had manifested and she fled to America to join the X-Men. However, Morph was unable to understand how her parent could hold a grudge for so long when she had saved the world several times and Mariko went on to explain that it was also because she was a lesbian. Morph was saddened by the news, as he had begun to develop feelings deeper than friendship for Mariko, but he understood.  
 
Later, whilst on a mission to rescue a group of children from a concentration camp Mariko tried to reach out to teammate Nocturne, who had just lost her boyfriend Thunderbird and subsequently miscarried her baby. Mariko showed concern for Nocturne, but was pushed away and told to leave her alone. Once the Exiles had successfully rescued the children they were then informed that they would have to kill one of the youngsters - David Richards. For the mission the Exiles had been joined by Weapon X - their more violent and ruthless counterpart. Whilst Weapon X had no objection to killing the child, the Exiles refused to do so and a fight ensued. Mariko managed to best Weapon X member Storm during the fight. Eventually, a resolution was made when Weapon X's Sabretooth agreed to stay behind and look after the child, which the Timebroker agreed to.
 
Mariko's relationship with Morph was put to the test during a mission where they had to stop a bomb from going on in a California that was run by giant lizards.  Morph made his feelings for Mariko clear.  He retained a humourous tone when offered to transform into woman's form so the two could have sex.  However, she turned him down.
