A fictitious character called Elektra Natchios appears in American comic books published by Marvel Comics. The character was created by Frank Miller and debuted in Daredevil #168 (January 1981). She is a romantic interest of Matt Murdock, a.k.a. Daredevil, but their relationship is strained by her aggressive demeanor and mercenary way of life until 2020, when she turns into the second Daredevil.

The character is a highly trained assassin of Greek descent who wields a pair of sai as her trademark weapons. Elektra is one of Frank Miller’s best-known creations, and has appeared in numerous modern storylines even though Marvel had originally promised not to revive the character without Miller’s permission. She has also appeared as a supporting character of the X-Men’s Wolverine and in other series and mini-series, as well as adaptations for the screen.

Jennifer Garner portrayed Elektra in the films Daredevil (2003) and Elektra (2005), while Élodie Yung portrayed the character in the Marvel Cinematic Universe television series Daredevil[4] and The Defenders.
