Rocko was exposed to your typical outer space meteor radiation. He was standing too close to a bull at the time, thus became half man, half bull. He soon joined a team calling themselves the Zoo Krew Krushers. The Krushers were defeated time and again by various super hero teams. Rocko got tired of this type of life. He had always been good at numbers and economics in school, so he tried his hand at Wall Street. To his pleasant surprise, Rocko was a Wall Street wizard. He now lives a comfortable life commuting from his home in South Jersey to New York. His old Zoo Krew Krushers teammates call him "Wall Street". To this day, Rocko can't tell if they're praising or mocking him.
