Dean Matthew Roll (born January 28, 1975) is an American professional wrestler, best known for his appearances in Total Nonstop Action Wrestling (TNA) under the ring name Shark Boy.

Prior to his appearances in TNA, Roll competed on the independent scene from the mid-1990s onwards before being signed by World Championship Wrestling (WCW) in 1999.

Following his release from WCW six months later in 2000, Roll returned to the independent scenes, mainly competing for the World Wrestling All-Stars (WWA) promotion.

[6][7] Later that year, Roll 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.

[5] On May 19, 1999, Shark Boy wrestled at the second annual Brian Pillman Memorial Show, defeating Matt Stryker, Tarek the Great and Chip Fairway in a tournament and receiving a trophy.

As a result of the exposure gained by his appearances on television and at the Brian Pillman Memorial Shows, coupled with his "cult" following, Shark Boy was signed to a contract by World Championship Wrestling in 1999.

[6] During this same time from 2002 till its closing, Shark Boy joined and toured with XPW where he had memorable bouts with Kaos, Tracy Smothers, Juventud Guerrera, and Jerry Lynn.

His most notable trainees are Dustin Thomas, Tom Bellman, Darrell Hazel, Jerrod West, Todd Mullins, Ed Gonzales, Donny Redd, Chris Ledbetter, Jake Omen, Tony X and Cannonball Sami (Sami Callihan)[6][10] On July 31, 2002, Shark Boy made his Total Nonstop Action Wrestling (TNA) debut in a dark match losing to Jimmy Rave.

[14] He made his return to the ring on the December 24 edition of Xplosion, in a losing effort against Robbie E. On March 3, 2011, Shark Boy announced on his website that he had requested and was granted his release from TNA.

On March 17, 2013, Shark Boy appeared on TNA 10 Reunion where he was in a 10-man Gauntlet match, which was won by Matt Morgan, that aired on August 2, 2013.

[citation needed] He then made another appearance on November 21 at TNA Turning Point, facing Ethan Carter III in a losing effort.

He made an appearance in the October 29 taping during a backstage segment where he was signing autographs, getting a pep talk from road agent Pat Kenney to get back to being "the real shark" referring to when he was in his prime.

On the July 9, 2015 episode of Impact, he returned as a competitor in Ethan Carter III's 3 vs 1 Gauntlet Match for the TNA World Heavyweight Championship in a losing effort.

He didn't wrestle from November 2018, until April 2019 when he was involved in a six way scramble match at Joey Ryan's Penis Party WrestleCon event during WrestleMania 35 weekend.

In November 2005, it emerged that Miramax had attempted to have the case dismissed, in addition to requesting that the court nullify Roll's trademark on the basis that "Plaintiff is a male whose services are rendered only when he is wearing a costume depicting 'shark-like' attributes.
