Open the Dream Gate Championship
On April 24, former WORLD-1 members Hulk, PAC, Yokosuka and Yoshino agreed to form a new alliance with Masaaki Mochizuki to battle Blood Warriors. On May 21, Hulk first defeated CIMA in the semifinals and then CIMA's Blood Warriors stablemate Yasushi Kanda in the finals to win the 2011 King of Gate tournament. However, much to Hulk's surprise, Masaaki Mochizuki named Kanda the next challenger to his Open the Dream Gate Championship. On June 8, before Hulk was scheduled to team with Shingo Tagaki, Naoki Tanizaki came out dressed as Black Hulk. With Takagi distracted with Tanizaki, Hulk hit Takagi with a chair, turning heel and joining Blood Warriors. Hulk finally received his shot at the Open the Dream Gate Championship on July 17, but was defeated by Masaaki Mochizuki. On August 7, Hulk and Akira Tozawa defeated Masaaki Mochizuki and YAMATO in the finals to win the 2011 Summer Adventure Tag League. On December 1, Hulk and Tozawa defeated KAGETORA and Susumu Yokosuka to win the vacant Open the Twin Gate Championship. On January 19, 2012, Hulk and Tozawa turned on CIMA, causing him to lose a ten-man "Loser Leaves Unit" tag team match; as a result, CIMA was kicked out of Blood Warriors. On March 1, the new leader of Blood Warriors, Akira Tozawa, changed the stable's name to Mad Blankey. On March 4, Hulk and Tozawa lost the Open the Twin Gate Championship to Jimmy Kagetora and Jimmy Susumu. Hulk regained the title from the Jimmyz on June 10, teaming with "Naoki Tanisaki". However, they lost the belts back to Jimmy Kagetora and Jimmy Susumu on June 17 in a 3-way elimination tag team match which also included MadoGiwa Windows members K-ness &amp; Kenichiro Arai. On August 19, Hulk, Tozawa and Naoki Tanisaki defeated CIMA, Gamma and Magnitude Kishiwada to win the 2012 Summer Adventure Tag League and the vacant Open the Triangle Gate Championship. They lost the title to Kaettekita Veteran-gun (Gamma, HUB and Magnitude Kishiwada) on October 21. On June 15, 2013, Hulk and Tozawa regained the Open the Twin Gate Championship from Shingo Takagi and Yamato, when Yamato turned on Takagi and joined Mad Blankey. Hulk and Tozawa went on to lose the title to Naruki Doi and Ricochet on July 21. On May 5, 2014 after being the last to escape and win the Cage match at Dead or Alive 2014, Hulk quit Mad Blankey, thus turning face. After losing the rights to the Mad Blankey name and logo, he soon began a gradual return to his dancer gimmick, teaming up with Masaaki Mochizuki (who was competing as BxB Masa) on July 3, 2014 to unsuccessfully challenge the Mad Blankey team of YAMATO and Naruki Doi after Hulk was attacked by Dr. Muscle. On July 20, Hulk defeated YAMATO to win the Open the Dream Gate Championship for the first time. After a reign of only 16 days, Hulk lost the title to Naruki Doi in a four-on-one handicap match on August 5, which also included Doi's Mad Blankey partners Cyber Kong, Kzy and Mondai Ryu. On August 17, Hulk defeated Doi, now recognized as a "provisional" champion, in a one-on-one match to resume his first title reign and make his first successful title defense. On September 9 BxB Hulk formed his new stable called Dia Hearts alongside Maasaki Mochizuki and Dragon Kid. On October 5, Hulk made his 2nd successful title defense against Cyber Kong of Mad Blankey. On November 2, Hulk made his 3rd successful title defense against Monster express member and former tag team partner Akira Tozawa. On December 28, BxB Hulk successfully defended his belt for the 4th time against Shingo Takagi. Hulk separated his shoulder during the match but was not forced to vacate and made his surprise return January 11, 2015, defeating Punch Tominaga. On June 14, Hulk lost the Open the Dream Gate Championship to Masato Yoshino in his eighth title defense. On February 4, 2016, Dia.HEARTS was forced to disband after losing a match to Monster Express and VerserK. On May 28, Hulk, along with YAMATO, Kzy, and Yosuke♥Santa Maria, formed a new unit named Tribe Vanguard.
