Frederick

Frederick is introverted and very shy, unlike his older brothers Blaine and Lance; it is noted that, for many years, he had no friends.

Frederick is seventeen, making him the youngest Plaid Brothers. His skin color is fair with a slight pink tint, and can become as red as a tomato when blushing or embarrassed. He has large (pretty, as dubbed by Gwen the first time she described him), bright green eyes, like the color of summer vegetation.
