I only cosplay a character for two reasons, I love the character, or to help out my sister's cosplay. For example, she would be Gary King from the Cornetto trilogy, and I would cosplay as Andy to go along with her. For myself? I mostly cosplay Arthur Dent from The Hitchhiker's Guide to the Galaxy, along with Mycroft Holmes from Sherlock. They're my favourite characters, I feel an emotional connection to them, and I just love being them for a con lol
