What the Name Means

A King Killer Hunts the Person at the Top.

Not out of envy. Out of respect for the work it took to get there. In combat sports, the king is the champion. Your job is to train, climb the rankings and earn the right to meet them.

That same mindset follows us outside the ring: study the standard, do the hard work and never confuse confidence with entitlement.

Meet the Founder

Built Between Fight Camps.

Michael “Heck” Heckert fell in love with combat sports after watching local cage fights with his dad. The obsession became a career across MMA, boxing and professional bare-knuckle fighting.

King Killers started in 2021 as a way to turn that life inside the fight game into gear with an honest point of view. Every order supports an independent, fighter-owned business—and helps keep the next camp moving.

“Our goal is to work through the rankings until we earn the matchup with the king.”
