Catwoman and Elektra are pretty evenly matched and both of them can be lethal in close combat. I would still have to give Elektra the edge because she seems like the better fighter and her twin blades make for very good weapons. They aren’t called twin blades if we’re being technical, but that’s essentially their main function. Catwoman has her whip, but Elektra is skilled enough to dodge the blows and turn things to her advantage. Elektra wins.
