Gregory is a cricket who lives on King Kai's planet. He is sometimes seen as the voice of reason of the group, such as asking King Kai whether it was appropriate for him to start making bets regarding Goku and Vegeta's battle; pointing out the the Earth could be destroyed it Goku loses (however, he immediately betted 1,000 zeni on Goku after being threatened by King Kai). He occasionally gets ignored by King Kai and suffers some verbal abuse in the form of being smashed by a large mallet. He was once mistaken as a grasshopper by King Kai, though it's likely he just didn't care.
He is voiced by KaiserNeko.
