Originally created back in 1934 by writer Roy Thomas and artist Barry Windsor-Smith, Red Sonja was a companion of Conan the Barbarian and Marvel Comics showcased the "she-devil with a sword" back in a comic in 1973. As a redhead with a hot temper, Sonja has always been feisty and she was designed as a pinup model, per her hourglass figure. But despite her alluring shape, she has a very violent side; and most of the Red Sonja comics are rated Mature, per their bloody and gory content.
The bikini she wears, comprised of "circular scale mail armor plates", is part of her signature. And the large broad sword she carries is certainly a lethal weapon. The cosplay pic on the left showcases Bianca Beauchamp [a popular Canadian latex model often featured in this blog] and she is dressed as a sexy female Barbarian; while the pinup poster of Red Sonja on the right was drawn by Kitsunx at DA and colored by Vest.
"Savage Red Sonja" and "Queen Sonja" are amongst the monikers that she's adopted over the years. And Sonja has teamed up with a few characters during comic crossovers, including Conan, Claw, Spider-man and Wolverine [apparently she must be a damn time-traveler, but I'll leave the mechanics of that issue alone for now].
Here are a few pinup posters / drawings of the sexy Red Sonja by various artists, including Ed Benes, Marc Silvestri and J Scott Campbell. And despite Bianca's latex attire in the first pic above, I took the liberty of assuming she was shooting for a modern version of Red Sonja, since the metallic bikinis are probably hard to find in stores.
