It's Corpofan

The Daishomon were something that was made up during a casual discussion with some friends around the time Gold and Silver came out. The conversation was about names we refer to ourselves by (ex: Sam, Samantha, Squiggy) and attributing them to poke'mon levels. Now I don't have any other names I go by besides "Ryan" so I asked, "so what does that make me?" and someone said "a legendary Poke'mon".

So I started turning Daisho staff into Poke'mon, or Daishomon. This is of the con-chairs who I modeled after his con character "Corporate Fan Boy", who always wore a white mask with red and blue stripes.

More to come, I'm sure.
