Elektra Natchios, usually referred to only by her first name Elektra, is a fictional character in publications from Marvel Comics.
Elektra is a kunoichi – female ninja assassin – of Greek descent. She wields a pair of bladed sai as her trademark weapon. Created by Frank Miller, Elektra first appeared in Daredevil #168 (January 1981). She is a love interest of the superhero Daredevil, but her violent nature and mercenary lifestyle divide the two. She is one of Frank Miller's best-loved creations, and subsequent writers' use of her is controversial as Marvel had originally promised to not resurrect 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.
In the 2003 film Daredevil and its 2005 spinoff, Elektra, the character is portrayed by Jennifer Garner. Elektra was ranked 22nd in Comics Buyer's Guide's 100 Sexiest Women in Comics list. Miller initially based the character's appearance on Lisa Lyon, a female bodybuilder.
