It seems there really is a character named "Lady Deathstrike" in the 2003 superhero film X-Men 2, and this is how she looks as played by the actress Kelly Hu.
Spoiler: Lady Deathstrike is not one of the superheroes. "Her father Lord Dark Wind created the adamantium-bonding process that was forced on Wolverine by Weapon X. A self-styled warrior, Lady Deathstrike hired the villain Spiral’s 'body shoppe' to bond adamantium to her own skeleton in addition to other cyber-genetic enhancements." But you already knew that. (Still, hat tip to Wikipedia for those details.) Kelly Hu was born in 1968, so she turned 35 the year X-Men 2 was released.
