Michael Alexander "Mikey" Simon is the titular protagonist of Kappa Mikey. He is a 19-year-old American from Cleveland, Ohio and is the only American main character on LilyMu.
The main joke of the series is that while Mikey is drawn in a typical American cartoon form (thicker outlines, round eyes, large head, only eight fingers), his Japanese co-stars are drawn in a traditional anime style (thinner outlines, more detail, large eyes and mouth, all 10 fingers; use of various face-faults).
