A few weeks later , he lost to Storm , then came back in October 1993 to win the belt for the second time . Once again , Storm defeated him a few weeks later , and Tenzan headed back to the NJPW . Tenzan then began teaming with Masahiro Chono as Chono Team Wolf . In June 1995 , Tenzan and Chono won the IWGP World Tag Team Championship in a tournament , which they held for a month until the title was vacated due to Chono missing a match when his father died . Tenzan had a brief tenure in WCW and At Starrcade 1995 , he was defeated by " Macho Man " Randy Savage . In July 1996 , Tenzan and Chono won the IWGP Tag - Team titles again , this time beating Kazuo Yamazaki and Takashi Iizuka . They held the titles for over 5 months before losing to Tatsumi Fujinami and Kengo Kimura . A few weeks later , Tenzan and Chono became founding members of nWo Japan . For the rest of 1997 , Tenzan and the rest of nWo Japan continued the nWo tradition of attacking their various enemies . Tenzan got his third chance for the IWGP Tag - Team Titles in July 1998 , after Chono ' s former tag - team partner Keiji Mutoh was injured . Tenzan and Chono went on to win the tournament and the belts . A month later , they were defeated by Genichiro Tenryu and Shiro Koshinaka . Tenzan continued to feud with Koshinaka , eventually getting a new partner in Satoshi Kojima . The two teams fought at the Tokyo Dome in January 1999 , with Tenzan & Kojima coming through , defeating Koshinaka & Tenryu to get the IWGP Tag - Team belts . A few months later , Koshinaka retook the titles from Tenzan & Kojima , with his partner Kensuke Sasaki . For the next year , Tenzan continued to wrestle in NJPW , feuding with Koshinaka , Masa Chono , Manabu Nakanishi , and others . He defeated Chris Benoit at the Tokyo Dome in January 2000 . In July 2000 , Tenzan , still teamed with Kojima , got the IWGP Tag - Team Titles for the 5th time , winning over Manabu Nakanishi and Yuji Nagata . Tenzan & Sasaki feuded with Nakanishi & Nagata for the next few months , with Tenzan & Sasaki coming out on top . On February 24 , 2002 Tenzan made a brief appearance at WWA The Revolution pay - per - view from Las Vegas , Nevada where he choked Disco Inferno . Scott Steiner then attacked Disco in the ring . Tenzan could be seen sitting right behind the announcer ' s table when Disco joined commentary . He can be seen leaving the arena following Steiner ' s attack on Disco . Tenzan also won the IWGP Tag Team Titles in March 2002 with Masahiro Chono ( their title reign lasting over one year ; it also tied the team record for most championships won with Fujinami & Kimura ) , and again in December 2003 with Osamu Nishimura . In November 2003 , Tenzan finally won the IWGP Heavyweight Title from Yoshihiro Takayama . He proceeded to win it three other times ( in February 2004 from Genichiro Tenryu , December 2004 from Kensuke Sasaki and May 2005 from Satoshi Kojima ) . He lost the championship to Kojima in a cross - promotional champion vs . champion match . Kojima held the AJPW Triple Crown Championship . The match ended when Tenzan was unable to get up , Kojima thus winning by a knock out . Tenzan got heat with the management of NJPW due to this , because he gave NJPW ' s most prestigious championship ' s control to the rival company , AJPW . This supports the speculation that the match didn ' t end the way it was booked to , and that Tenzan was really unable to get up and finish the match . Tenzan defeated Kojima in a rematch three months later , bringing the championship back to NJPW . He lost the championship to Kazuyuki Fujita on July 18 , 2005 . Tenzan competed in the 2005 G1 Tournament , and almost made it to the semi - finals . in October 2005 Tenzan and Chono reunited to win the IWGP tag team title for a fifth time from Hiroshi Tanahashi and Shinsuke Nakamura . On August 13 , 2006 Tenzan defeated long time rival Satoshi Kojima in the final of the G - 1 Climax , becoming only the second wrestler to go undefeated in a round robin style G - 1 . This would be his third G - 1 title . After severing ties with his old mentor Masahiro Chono , Tenzan founded the heel unit GBH ( " Great Bash Heel " , affectionatley referred to by fans as " Great Big Head " ) ; it is composed of Tenzan , Togi Makabe , Shiro Koshinaka , Toru Yano , Tomohiro Ishii and Tomoaki Honma . Speculation has been rampant since December about Tenzan ' s future in New Japan , and he still has yet to have formal contract talks with NJPW during their annual contract signings .
