Kenneth Wayne Shamrock (born Kenneth Wayne Kilpatrick; February 11, 1964) is an American mixed martial artist, UFC Hall of Famer and professional wrestler. Shamrock emerged as one of the biggest stars in the history of mixed martial arts, headlining over 15 main events and co-main events in the Ultimate Fighting Championship and Pride Fighting Championships during the course of his career and set numerous pay-per-view records with his drawing power. Shamrock is widely considered to be a legendary figure and icon in the sport of mixed martial arts. Shamrock was named The World's Most Dangerous Man by ABC News in a special entitled "The World's Most Dangerous Things" in the early part of his UFC career, a moniker which has become synonymous as his nickname.
Shamrock became known early on in the UFC for his rivalry with Royce Gracie. After fighting to a draw with Gracie in the inaugural Superfight, he became the first UFC Superfight Champion after defeating Dan Severn at UFC 6; the title was eventually renamed the UFC Heavyweight Championship when weight categories were introduced to the UFC. He was also the first foreign MMA Champion in Japan, winning the title of King of Pancrase. During his reign as the UFC Superfight Champion, he was widely considered the #1 mixed martial artist in the world. Shamrock was also ranked by Inside MMA as one of the top 10 greatest mixed martial arts fighters of all time.
Shamrock is the founder of the Lion's Den mixed martial arts training camp. The Lion's Den became one of the most successful camps in mixed martial arts history and was famous dominating the early scene of mixed martial arts. He is also the older adopted brother of former UFC Middleweight Champion Frank Shamrock.
Along with his mixed martial arts career, Shamrock enjoyed considerable success in professional wrestling, achieving championship success during his tenures with the World Wrestling Federation and Total Nonstop Action Wrestling. Among other accolades, he is a one-time NWA World Heavyweight Champion, one-time WWF Intercontinental Champion, one-time WWF Tag Team Champion, and the 1998 WWF King of the Ring. World Wrestling Entertainment—formerly the World Wrestling Federation—has credited Shamrock for popularizing the ankle lock (later used by fellow professional wrestling world champions Kurt Angle and Jack Swagger), which was named by the organization as one of the top five submission holds in history.

MMA career

Pancrase Hybrid Wrestling (1993–1996)

The origins of Shamrock's mixed martial arts career began in the Japanese pro wrestling organization Fujiwara Gumi. On October 4, 1992, at the Tokyo Dome, a legitimate match between "Wayne" (Shamrock's show title in Japan) Shamrock and kickboxing champion Don Nayaka Nielsen took place. Shamrock took Nielsen down and submitted him with an arm lock in 45 seconds. The success of this match made young pro wrestlers Shamrock, Masakatsu Funaki and Minoru Suzuki question what they had been told since entering into predetermined wrestling: that nobody would ever pay to see real matches.
Shamrock, Funaki and Suzuki then founded a group of pro wrestlers and decided to pursue marketable legitimate matches. They formed a promotion called Pancrase, named by ’60s wrestling star Karl Gotch after the sport of Pankration in the ancient Olympics, which combined all different forms of fighting into one sport. Using pro-wrestling rules – no closed fisted punching to the head (closed fisted punches were allowed to the body), breaks on the ropes, but fighting for real – Shamrock beat his friend and mentor, MMA legend Masakatsu Funaki by arm-triangle choke in the main event of the very first Pancrase show on September 21, 1993. The show attracted a sell-out audience of 7,000.
Shamrock, now an enormous star in Japan,defeated world kickboxing champion and future UFC Heavyweight Champion Maurice Smith and Alex Cook in the Opening Round of the 16 man King of Pancrase Tournament and Masakatsu Funaki and Manabu Yamada in the Second Round to become the first King of Pancrase before crowds of 11,000 fans both nights at Tokyo’s Sumo Hall in December 1994. He then defended his King of Pancrase title against Bas Rutten in 1995, submitting him with a kneebar. He lost the title in his next fight against Pancrase co-creator, Minoru Suzuki.
In addition to his MMA bouts in Pancrase, Shamrock also competed in a kickboxing match in 1994 with kickboxing legend Frank "The Animal" Lobman, who holds a pro record of 110-6 with a 90% KO ratio. Shamrock broke Lobman's nose with a right cross early in the bout but was ultimately defeated by TKO due to leg kicks.
Shamrock eventually had a falling out with Pancrase management in early 1996 and left the company to compete in the UFC full-time. Shamrock left Pancrase with a record of 17-3.

Ultimate Fighting Championship (1993–1996)

On November 12, 1993, after the first three Pancrase shows, Shamrock returned to America to fight in the newly formed Ultimate Fighting Championship (UFC), despite fighting in Japan just four days earlier. Masakatsu Funaki served as Shamrock's head trainer for the event.^{[citation needed]} The event was held under a one-night tournament format with minimal rules (in contrast to Pancrase, which had extensive rules and a gentleman's agreement not to strike on the ground). Shamrock's first opponent was Patrick Smith. In the opening seconds of the fight, Smith came forward and threw a leg kick, but Shamrock shot off the kick for a double-leg takedown. Following some ground and pound, Shamrock seized Smith’s right leg and dropped back, applying a heel hook, forcing Smith to tap out.
