Elektra Natchios, usually referred to only by her first name Elektra, is a fictional character in publications from Marvel Comics. She is a kunoichi - female ninja assassin - of Greek descent. She wields a pair of bladed sai as her trademark weapon. 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. According to Marvel Comics, Elektra is the world's most lethal woman and one of Marvel's most cold-blooded characters. She has killed more men than just about any other Marvel character while remaining one of the most popular heroines in the Marvel Universe.
