Medusa is a character name (Wikipedia: In Greek mythology, Medusa (/məˈdjuːzə, məˈdʒuː-, -sə/, US: /məˈduː-/; Μέδουσα "guardian, protectress") was a monster, a Gorgon), therefore  Gorgon is the correct term. The wiki used to have Medusa because that was what Jin called them, but he must have shared the misconception that it is the term to describe the species, rather than the famous Gorgon's name.

As for capitalization, it depends for importance for me. In usual speech I would not capitalize it, but in regards to KagePro I likely would, as it related to the universe of the story.
