Origin
Elektra Natchios was Matt Murdock's (Daredevil) first love interest,  but he and she split up after the death of her diplomat father during a hostage crisis.  Her mother had been killed when she was young during an assassination attempt upon her father.

Already a master martial artist, having killed many people due to schizophrenic tendencies, she went to further her study of martial arts with a cult called the Chaste, in an attempt to find inner peace.  She was forced to leave the order by the group's leader, Stick.

In an attempt to prove herself worthy of the Chaste, she joined their enemies the Hand with the intentions of causing the groups' downfall from the inside, but she was seduced by the cult becoming one of them.

Leaving the Hand she moved to New York, where she became the lead assassin of the mob boss known as the Kingpin.  She came into conflict with her former lover Daredevil when she attempted to kill his civilian law partner Foggy Nelson.  Failing to fulfill her mission she was executed by the Kingpin's new assassin Bullseye.

Although she died and was apparently resurrected by the Hand, the process leaves in doubt her stability or sanity, but she remains one of the world's deadliest assassins, the ninja known as Elektra.
