Medusa first appeared in Fantastic Four #36 (1965), and was created by Stan Lee and Jack Kirby. She appears first in flashback, then in costume as part of the fledgling Frightful Four. She appears in #38, 41, 42, 43, 44-48 and in various subplot glimpses from #49-62. The Inhumans also appear in Fantastic Four # 82-83, with Medusa.
The main collection of the brand is Versace, which produces upmarket Italian-made ready-to-wear and leather accessories, while other diffusion lines are Versace Collection (mainly in the US), Versus Versace and Versace Jeans. The Versace logo is the head of Medusa, a Greek mythological figure. The logo came from the floor of ruins in Rome that the Versace siblings played in as children. Gianni Versace chose Medusa as the logo because she made people fall in love with her and they had no way back.
