Serial about human with super power

Hello
I’m looking for a movie starring a woman who did not die and joined a group that stopped people with special abilities. In one of the episodes, the woman was taken to a fake hospital where they tried to remove her bone marrow without Extract intelligence to be able to use his immortal power. In another episode, he killed the mother of a murderer so that he, who had the power to pull back time, would pull back time and prevent someone from dying.
The series is from 2000 onwards. In another episode, the group’s headquarters was attacked and computers were shut down, forcing them to enter a bathroom and test the remaining hair.
