When Garlic Jr. escaped from the Dead Zone, Mustard and Salt killed a few innocent people.
At Kami's Lookout, Mustard fought Krillin, and brutally beat him up by grabbing him and kneeing his head. After Salt nearly killed Krillin, Gohan unleashed his hidden power. Salt and Mustard used a devastating attack on Gohan, but he blocked it easily. After Gohan killed Salt, Mustard attacked Gohan in revenge, but Gohan kicked him in the face and destroyed him with a Masenko.
