―Lady Deathstrike[src]

Yuriko Oyama, also known as Lady Deathstrike, was a mutant in the employ of Colonel William Stryker.


X2: X-Men United: The Movie Prequel: Nightcrawler

Yuriko Oyama was bonded to the metal adamantium and her beaten body was put in the same cell as Kurt Wagner. While Kurt was comforting her, she started writhing in pain as her claws start to come out. He called for help and some of the men that were holding them prisoner came into the cell, wondering why her claws were not removed and instead coated with adamantium. Later on, she is resting and looking better with her hair starting to grow. Kurt tells her that they will get out somehow.

X2: X-Men United: The Movie Prequel: Wolverine

When Stryker was told about the Adamantium being rejected by Sabretooth, Stryker said that it was fine because they already had a new successful candidate.

She became Colonel William Stryker's assistant after he used the Mind Control Serum on her. She was also involved in the same government program as Wolverine, giving her adamantium claws that extend from the tip of her fingernails, instead of from her knuckles. On Stryker's orders, she ambushed and successfully captured both Cyclops and Professor X. While Stryker was interrogating Professor X, the effects of the serum wore off and Stryker demonstrated on her how he controls mutants to Professor X. Wolverine defeated her in a fight by impaling her with a fluid adamantium injection and leaving her presumed dead (but actually unconscious and severely wounded) in the water tank in the laboratory where Wolverine got his Adamantium claws; the Adamantium metal inside her solidified and preserved her unconscious form inside the water tank. When she was impaled by Wolverine, she broke free of Stryker's control, but there was now nothing she could do to save herself. The adamantium leaked from her eyes, nose and ears and she fell backwards into the tank with a thud as the metal hardened in her body.

Character traits

Yuriko Oyama was an incredibly skilled martial artist, disposing of a great agility and a deep knowledge of combat. She was also incredibly strong, able to throw Wolverine across a room and similarly leap such distances herself. She possesses a healing factor equal to Wolverine's. William Stryker gave her retractable adamantium claws, presumably along with an adamantium skeleton, with one sprouting from the tip of each finger. She possesses a healing factor equal to Wolverine's. However, it is unclear exactly what her mutation was, as Stryker's dialogue suggests her ability to heal was what makes Wolverine no longer "unique". That and her altered eyes appear to be the only natural mutations she had, as it was strongly implied in the film that her claws are entirely artificial.

She shows a cold and calm character, but she was later revealed to be under Stryker's mental control, so her real personality remains unknown.
