I figured I would come back around to this eventually. So, this part I always mix up. I remember there being a bunch of color variants for Electra, but they were also different characters. I mix it up a bit with Maximum Carnage since in that game every color variant got a different name. Streets of Rage had both. But if I'm remembering correctly, blue, silver, and red were all direct Electra variants.

Feet were from Black Widow, resculpted into proper heels. Sculpted the top of her boots, her right bracer, and her hair. Whip was an Omega Red tendril. Added a peg to it so it could be turned independently from the arm. From there, a full repaint, and all done!
