Duck-chan
Duck-chan was created in response to the original artist of Duck-chan, Vixit, finding it strange when Joe said "Fuck a duck" in frustration once. The part on the original fanart of her about Psyduck is a reference to the time in the Yakuza 0 streams when Joe accidentally said "It's like Pokémon porn", in reference to the collectible porn cards in that game.[1] (Yes, this one really was drawn more than once).
