Schwa was once a frequent visitor to the board before the end of the Second Incarnation and subsequent drop in activity. He was particularly fond of Role-Playing and storytelling. After a few weeks from when the board opened back up, he seemingly disappeared. Now he occasionly drops in to watch the board. He is often depicted as a man wearing white garbs and a black blindfold.
He is noted for starting the semi-popular Super Mario Arena, a thread in which users would bet on who would win the next match using virtual coins. After 10 rounds, the thread ended in the middle of a role-playing tournament in which entrants created their own Mario-based monster to enter.
He maintains a website here.
