The purpose of this study is to analyze the specific mimesis types of common character costumes in MMORPGs, which have stories that are very similar in structure to ancient myths and fantasy novels. As the subject of the research I have selected "Diablo 3" created by the American video game developer, Blizzard Entertainment Images of 5 characters, for both genders - Barbarian, Witch Doctor, Monk, Demon hunter, Wizard - were compiled for a total of 10 images, and these images were compared to popular archetypes in mythology, religion and literature. analyzed them separately according to the mimesis type. For this study, Articles and books containing the Aesthetics, Mimesis and Digital culture were researched in order to study the costume features and the Mimesis types and compare them to the costumes in the MMORPG. Firstly, the character Barbarian is a successor of the barbarian character of the previous product. The outfit worn by the game figure is based on the common images expressed in the movie <Conan-The Barbarian>. The makers created an analogous-imitation mimesis by replicating the image in an exaggerated and grand form. Second, the character Witch Doctor derived its motif from the Voodoo cult, and was expressed in analogous-imitation mimesis, using the very shades and patterns used in real life. Third, the character Monk, blending the image of a priest in Eastern Europe and images of its oriental counterparts, was expressed in transposition-diversion mimesis. Fourth, the Demon Hunter took the source of its inspiration from the image of a Witch hunter in the medieval times. The game character has a sharper sleeker figure than its model, and uses more acute shapes and darker gloomier colors expressed in an analogous-imitation mimesis. Finally, the character Magician took a formless character and expressed it in transposition-diversion mimesis taking as its basis some fantasy novels.
