Great-O-Khan
About Great-O-Khan
One of United Empire’s most decorated pillars, Great-O-Khan — real name Tomoyuki Oka — built his foundation as an amateur wrestler before joining NJPW’s dojo and embarking on a career-defining excursion to RevPro, where he ran off an unbeaten streak of over 800 days. Back in NJPW from 2020 as a founding member of United Empire alongside Will Ospreay, he has accumulated five IWGP Tag Team Championship reigns — twice with Jeff Cobb, once with Callum Newman, and twice with HENARE — plus the 2024 KOPW Championship and a NJPW World Television Championship run.
Most recently, O-Khan and HENARE recaptured the IWGP Tag Team titles at Dominion 6.14 on June 14, 2026, dethroning the Knock Out Brothers (OSKAR & Yuto-Ice) after a 250-plus-day reign. The pair also hold the NEVER Openweight 6-Man Tag Team titles alongside the returning Will Ospreay, and both have earned G1 Climax 36 berths as a result of their Dominion victory, with the duo also eyeing a potential Forbidden Door appearance.
