Dean Roll (born January 28, 1975) is an American professional wrestler, better known by his ring name Shark Boy. He has been wrestling for Total Nonstop Action Wrestling since 2002.
Roll began training under Les Thatcher in October 1995 at the age of twenty. He debuted on May 3, 1997 in Thatcher's Heartland Wrestling Association, wrestling as the masked El Piranha. An HWA mainstay, Roll also occasionally portrayed the character of Dean Baldwin, the purported fifth, lesser known Baldwin brother.
Later that year, Roll (Shark Boy) debuted in the Independent Wrestling Association, where he developed the cartoonish character Shark Boy, partly inspired by the 1995 song "I Come From the Water" by the Toadies. In 1999, Roll trademarked the name "Shark Boy". In 1998, Shark Boy received a flurry of media attention. He was featured on ABC in an episode of 20/20 featuring professional wrestling, on the Discovery Channel as part of the annual Shark Week and on a documentary produced by MTV entitled True Life: I'm a Professional Wrestler.
