本研究試圖探究Cosplay在台灣的演變歷程,透過二手資料和深度訪談等方法,發現Cosplay在台灣20年來,歷經了迷文化到次文化的變遷過程:90年代附屬於社團活動之下的Cosplay是一種迷文化,角色扮演者實踐身為迷的過程,即對具體、單一的文本內容長時間的喜愛與投入,並匯聚成為組織性的迷群;千禧年後則是迷文化至次文化的過渡期,Cosplay的定義不斷被檢視與重述,而多元文本和角色更開啟了為扮演而扮演的模式;2005年後,角色扮演者個人化、偶像化與日常化,使Cosplay凝結成為「扮演風格」的文化形式,Cosplay不僅止於特定場域的角色扮演,而是可以隨意於日常生活挪用與擷取的美學態度。 This study aims to analyze the transformation from fan culture to subculture in the evolution of Taiwan’s cosplay activities in nearly two decades. The data were collected both from secondhand information and in-depth interviews. After analyzing and interpreting the data, this study found that cosplay has transformed from fan culture to subculture in the two decades in Taiwan. In the 90s, cosplay was used to be an affiliated activity, which revolved around a specific fan culture. In doing these cosplay practices, cosplayers felt their goals as fans had accomplished. They loved and devoted themselves into a specific part associated with a fan culture for a long time. The main motive that made they meet together was to form an organized fan group. However, since the 2000s, the cosplay in Taiwan has undergone a metamorphosis. Originally just an affiliated activity for a specific fan culture, nowadays cosplay has become a special subculture itself. The definition of cosplay has been reviewed and reinvented for several times. The diversity of subcultures and roles in cosplays, has transformed the mode of cosplaying as an activity for the love of cosplay itself. In 2005, cosplay has even become a personalized, idolized, and normalized activity, which made cosplay a culture of “cosplay style” among its participants. Today, cosplay is not only played in particular timing and places, but has become an aesthetic attitude, which people can freely adopt in their daily lives.
