Yankee usually makes very brief appearances, portrayed as a nerdy, fat character. He hates physical education class and frequently skips that class. He also frequently adds "dot com" to everything he says (for example, "He's totally lost it, dot com.") "Yankee" in Japanese slang refers to rebellious high school / junior high school students known for dying their hair and engaging in anti-social behavior. In a few episodes both in anime and manga, he is shown with a strange purple snake coming out of his mouth which even speaks in some episodes. This purple snake is known to scare Hibiki.
