After retiring from boxing, Obayashi announced his return to professional wrestling in July 2010. His in-ring return was delayed after he underwent further training and spent time to trying to build up body mass after losing a lot of weight for boxing. His official return to wrestling took place in November 2010 at Osaka Pro: Zeus Will Be Back, where he teamed with Daisuke Sekimoto to defeat Akebono and Don Fujii. Shortly after returning, Zeus re-ignited his old rivalry with The Bodyguard. The two traded wins back and forth for months, but eventually formed a tag team in early 2011 after Bodyguard was kicked out of the Joker stable and Zeus saved him from an attack by the rest of Joker. Known collectively as the Big Guns, they would go on to hold the Osaka Pro Tag Title for a short time in early 2011. The Big Guns started to achieve major success in 2013, winning the Osaka Tag Festival and the Osaka Pro Wrestling Tag Team Championship for the second time later that year. In the 2013 Tennozan, Zeus and Bodyguard faced each other in the finals with Zeus coming out victorious. On March 1, 2014, it was announced that Osaka Pro would be folding due to financial difficulties. On April 20, all of its workers became freelancers. It was later announced that the promotion would continue under new management, but Zeus and Bodyguard eventually vacated their all of their championships, and on April 20 wrestled their last match in OPW, teaming with Quiet Storm in a losing effort against Billyken Kid, Bull Armor Takuya and Black Buffalo.

Zeus made his debut for DDT in March 2014, when he and The Bodyguard defeated the Nuru Nuru Brothers (Michael Nakazawa & Tomomitsu Matsunaga). On September 13, Zeus received an opportunity at the DDT Extreme Division Championship, losing against Danshoku Dino in a "Kiss Pin" match. On February 15, Zeus won the Ironman Heavymetalweight Championship, defeating Soma Takao, but later that day he lost the championship back to Tomomitsu Matsunaga.

On March 28, Zeus and The Bodyguard made their debut for AJPW, defeating Menso～re Oyaji and Sushi. On May 16, Zeus and The Bodyguard received an opportunity at the World Tag Team Championship, but were unable to defeat defending champions Evolution (Joe Doering and Suwama). Zeus and Bodyguard both participated in the 2014 Ōdō Tournament as singles competitors, with Zeus being eliminated in the second round by eventual winner Go Shiozaki and Bodyguard in the first round by Takao Omori. Zeus and The Bodyguard participated in the 2014 World's Strongest Tag Determination League, finishing with 8 points but not making it to the final.

Zeus debuted with Zero1 in 2011, taking part in the 2011 Fire Festival, finishing with 3 points and therefore not advancing to the final. In September, he teamed with Masato Tanaka to capture the NWA Intercontinental Tag Team Championship from Kohei Sato and Kamikaze. Zeus and Tanaka held the title for over a year, eventually losing them to Yusuke Obata and Shito Ueda in November 2012. Zeus and James Raideen participated in the 2012 Furinkazan tournament, defeating Ueda and Obata in the final on December 15. On February 3, 2013, Kohei Sato and Zeus received an opportunity at the vacated NWA Intercontinental Tag Team Championship, but lost to Zero64 (Akebono and Daisuke Sekimoto). On July 30, Zeus defeated Ikuto Hidaka to win the NWA United National Heavyweight Championship. Zeus held the championship for 6 months, losing it in January 2014 to Tama Williams in his first defense and last appearance in Zero1 to date.

Obayashi began his career in Osaka Pro Wrestling, where he is a former Osaka Pro Wrestling Champion and 3 time Osaka Pro Tag Team Champion, winning the championship once with Gaina and 2 times with longtime rival and partner The Bodyguard. Outside of OPW, he is a former NWA Intercontinental Tag Team Champion, NWA United National Heavyweight Champion and winner of the 2012 Furinkazan Tournament with James Raideen in the Zero1 promotion, and a former Ironman Heavymetalweight Champion in Dramatic Dream Team (DDT).

In 2008, Zeus started to appear in other promotions, most notably facing and later teaming with veteran Toshiaki Kawada in Hustle. It was in Hustle that he picked up a clean singles win over former IWGP Heavyweight Champion Bob Sapp. Zeus produced his own show in December and hinted at a major announcement at Hurricane 2009. After defeating Bodyguard, Zeus announced that he was going to start training for a career in boxing and that he would be leaving the wrestling industry effective immediately.

In the run up to the 2006 Tennozan Finals, a brief video hyped up the debut of a mysterious new wrestler. That man was revealed to be Zeus, who would make his first appearance at that show, first bending a frying pan in a show of strength and then aligning himself with Gaina & Condor, taking out the OPW Seikigun. Soon after joining forces, the group dubbed themselves "Bad Force". Nicknamed "God of Destroy", Zeus went undefeated for several months after his debut. He teamed up with Gaina to win the Osaka Pro Tag Title shortly afterwards, but they would lose them at Hurricane 2007 to Hideyoshi & Masamune in a three-way match also featuring Tsubasa and Flash Moon. Zeus started to break out as a singles wrestler in late 2007, reaching the Tennozan final but losing to the Osaka Pro Champion, Tigers Mask. Super Delfin then started to take an interest in Zeus, offering to teach him more about professional wrestling and give him further training. Despite the rest of Bad Force’s protests, Zeus accepted Delfin’s offer and eventually left the group. After Hurricane 2008, he started the rookie group Blood & Guts (B&G), recruiting Daisuke Harada, Tadasuke and eventually Atsushi Kotoge to join.
