Appears in: "Sandwich of Death"

The Grand Master of Death Kwon Do is Sensai's sensei and is the main antagonist in "Sandwich of Death".


In the past, Grand Master took Sensai off the streets and raised him like his own son. Sensai later stole the recipe for the Death Sandwich and mass-produced it without his permission. Grand Master held a grudge against Sensai ever since.

Years later, when Sensai returned to the Death Kwon Do dojo to help Benson, who ate the Death Sandwich incorrectly and needs the Sandwich of Life, Grand Master refused to see him. After Sensai, Mordecai, Rigby, and Benson defeated all his guards and confront him, Grand Master revealed what Sensai did in the past. Despite Sensai saying he'll accept full responsibility for what he did in the past, Grand Master still refused to help him and ordered his guards to kill them.

When Grand Master pulls out an electric razor and is about to shave Mordecai and Rigby's mullet, Sensai jumped in front of the razor which shaves off some of his mullet, causing him to lose his ability to use Death Kwon Do. When Mordecai and Rigby are losing after Grand Master, he pulls out the Double Death Sandwich and launches it at Mordecai and Rigby. Before the sandwich reaches Mordecai and Rigby, Sensai teaches them a new Death Kwon Do move and sends the sandwich but to Grand Master causing him to accidentally eat the sandwich and die. After his death, the dojo falls apart.


  • Wicked
  • Murdeous
  • Unforgiving
  • Selfish


He has a mullet that's white and is extremely long in the back. He wears white robes and when he changes into his Death Kwon Do clothes, he only wears cutoff jeans.


  • The grand master may be a slight reference to Pai Mei from Kill Bill Vol 2 as he has bushy eyebrows,has long hair which is kept up in a ponytail and also is killed by being poisoned(in this case the death sandwich)
  • The fact that the Grand Master is meditating next to the Sandwich of Life and the Double Death Sandwich may be a reference to the concept of Yin and Yang.
