Brandon Wolff
Brandon W.K. Wolff (born October 18, 1975) is an American mixed martial artist and former Navy SEAL, nicknamed “Killer Bee.” From Kailua, Oahu, Hawaii, he fought in the welterweight division and has a pro MMA record of 13 wins and 6 losses.
He started his pro career in 2002, debuting with a first‑round knockout of David Santiago. After building a 7–3 record and facing UFC veterans, he signed with the UFC in late 2008. His debut was supposed to be against Jon Koppenhaver, who refused to fight, so Wolff instead faced Ben Saunders on December 10, 2008, and lost by first‑round TKO. He then lost to Yoshiyuki Yoshida at UFC 98 on May 23, 2009 and was released from the UFC.
In his next fight, he lost to Dylan Clay at X-1: Nations Collide on June 14, 2010, by kimura, giving him three straight losses.
Outside MMA, Wolff served as a U.S. Navy SEAL, completing BUD/S class 222 in 1999, earning the SEAL Trident, and leaving the Navy in 2001 as a Construction Mechanic Third Class. He has a twin brother, Brenton Wolff, who also served as a Navy SEAL and completed BUD/S class 223. Brandon later earned a bachelor’s degree from American Military University.
