Hirotaka Yokoi

After picking up a TKO win over Wilson Gouveia, the undefeated Yokoi fought former Pride Heavyweight Champion Antônio Rodrigo Nogueira in the opening round of the Pride Total Elimination 2004 tournament. Yokoi performed unexpectedly well, taking Nogueira down repeatedly with judo throws and pulling out reversals and occasional ground and pound on the Brazilian jiu-jitsu expert, but he ultimately fell to an anaconda choke in the second round for the first loss of his career.

After the All Japan affair, Yokoi diversified to his singles career aside from Rowdy, and challenged The Predator for the Zero-One United States Heavyweight Championship and Masato Tanaka for the NWA United National Heavyweight Championship. He and Sato also challenged for the NWA tag team titles several times, but they failed. From 2004 to 2006, Yokoi competed sporadically in Hustle as a member of the babyface Hustle Army, teaming up with "Hustle K" Toshiaki Kawada, while trying luck in Zero-One's Fire Festival tournaments and keeping his team with Kohei Sato. He was released from Zero-One in February 2007, leaving pro wrestling altogether.

Around the same time, in which their team was named as Rowdy, they started appearing in All Japan Pro Wrestling as Zero-One representatives. Sato and Yokoi put their eyes in the All Asia Tag Team Championship, taking part in a special league for the vacated title. Rowdy was successful, winning the belts against Turmeric Storm (Kazushi Miyamoto and Tomoaki Honma) in July 2003. They retained the title against challengers like King Adamo and King Joe and Nobukazu Hirai and Shigeo Okumura, but ended up losing it in October to the Zero-One team of Kintaro Kanemura and Tetsuhiro Kuroda.

Yokoi made his debut for the organization on November 24, 2002 at Pride 23 against Dutch kickboxer Jerrel Venetiaan, winning in the third round via armbar submission.

Yokoi joined Pro Wrestling Zero1 in May 2002. He started teaming up with other shoot-style wrestlers, namely Wataru Sakata, Yuki Ishikawa and Yoshiaki Fujiwara, and also enjoyed significant wins in the Fire Festival, beating Kohei Sato and Tetsuhiro Kuroda. He spent the rest of the year in random tag team matches, as well as losing efforts to Shinjiro Otani and Kazuhiko Ogasawara. Eventually, he formed a tag team with Kohei Sato in midst of the feud between the native wrestlers and Steve Corino's American faction, and they challenged Corino and CW Anderson for the NWA Intercontinental Tag Team Championship in two separate occasions, though coming short in both.

Yokoi made his professional debut in 2000 and won his first eight fights, mostly fighting in the RINGS organization before moving to compete in PRIDE. After RINGS's demise, he followed fellow judoka Tsuyoshi Kohsaka and joined his Alliance team.

Yokoi originally started training in judo in high school, but he was more interested in Universal Wrestling Federation and its offshoots. He participated at a Shooto mixed martial arts tournament during his stay at the Kinki University, and later moved to Fighting Network RINGS. Yokoi gained the nickname "Kaibutsu-kun" (meaning "Monster-kun") for his physical resemblance to the title character from the 1980s anime series Kaibutsu-kun.
