Profile cosplayer

A person who’s online profile is completely based on a fictional character, usually from a game or show.

For example: Username, basil. Pfp, basil fanart. Banner, basil. Bio: Basil quote.

The people may also go around on social media places making posts describing their “self” (the character they base themselves on, this is most common on tiktok) or comment a quote from that character or something that that character would say on a video.
