Her early history was unknown but it is stated that Wolverine had "dishonored" her family years ago presumably in Japan . She have vowed to kill him by any means necessary.
It is unknown, but likely, if Weapon X gave her the superhuman abilities she has.
When Wolverine was sent by Department H to stop Hulk's rampage and almost won, they quickly captured them and took them back to the Weapon X facility.
In his cell, Lady Deathstrike entered and said that he would die for the "dishonor" he brought to her family. Professor tried to reason with her that Wolverine is too valuable for Weapon X until he was stabbed by Sabretooth.
Then she released Wolverine and began to torture him with the help of Sabretooth. He took out the two then got out in his cell to find Bruce Banner.
After the two recovered, Sabretooth had decided to kill Wolverine without the Professor to object their decisions.
They began to attack Wolverine who rescued Banner from his reprogramming chamber in an ensuing battle. Team X nearly won if the Bruce had not transformed into Hulk and attacked them.
Lady Deathstrike attacked the Hulk who called her "ugly girl". She almost won until Hulk beat her, ripping her robotic arms off in the process.
As the Hulk destroyed the facility, Lady Deathstrike and Omega Red were never seen again and apparently killed. Deadpool, Sabretooth, and Professor were the only known survivors of Weapon X along with Wolverine's clone.
