真壁刀義
After severing ties with his old mentor Masahiro Chono, Tenzan founded the heel unit GBH ("Great Bash Heel", affectionately referred to by fans as "Great Big Head"); it was composed of Tenzan, Togi Makabe, Shiro Koshinaka, Toru Yano, Tomohiro Ishii and Tomoaki Honma. In February 2008, GBH turned on Tenzan with Makabe taking over the leadership of the group. Tenzan feuded with his former stablemates until the following October.
