Black Weasel is one of Nelson Muntz's two henchmen, along with White Weasel
. They are the youngest bullies at Springfield Elementary School. They look alike except Black Weasel is black and has a different hair style to White Weasel. He occasionally hangs out with Nelson after he was defeated by Bart. He only serves him on some occasions since then, but he appears in the series in other scenes involving the other bullies and mostly in scenes around the Springfield's children.
