The Swaptober Art Challenge event is an annual 30 day character art challenge created by Marcus Williams that runs from Oct 1 – Oct 30. The challenge is centered around the internet meme “Rule 63”, which states that, as a rule, “for every given female character, there is a male version of that character” and vice versa.
