Dokuo (毒男) is a recurring archetypal male figure associated with 2channel internet culture rather than a traditional anime character. The name is used to refer to a socially isolated, unlucky, or romantically unsuccessful man, often presented with irony or self-deprecating humor. In the 2channel context, Dokuo functions as a symbolic persona representing frustration, loneliness, and everyday complaints shared by anonymous users. He is less a single defined character and more a cultural mascot or shorthand for a certain type of online male identity.
