Hei (ヘイ Hei) is a dog-like creature that serves as a pet for Lord Jaguar in Dragon Ball Z: Bio-Broly.


The dog has the ability to shift between a normal, docile appearance and a monstrous form with red cat-like eyes as well as razor-sharp claws and fangs.



The dog in his docile appearance

Hei is shown at the beginning of the movie, growling at the Bio-Warriors as they are released from their tanks, and is later shown as Mr. Satan, Android 18, Trunks, and Goten arrive at Jaguar's island; in a humorous scene, Jaguar is shown to be small enough to ride on the creature's back. It later sneaks up on Trunks and Goten as they are spying on Hercule and the others, where it reveals its monstrous form; while Trunks is intimidated by the sight, Goten easily tames it and it takes a liking to him, leading Trunks to remark, "You have got to show me how you do that."

Culture Fluid Effect

The Culture Fluid disentegrates Hei

When Bio-Broly is released, the dog tries to attack him despite being scolded by Jaguar, only to end up the first victim of the Culture Fluid.


  • Hei's name, together with Dr. Collie, Nain, and Men-Men, is a reference to the Jōji Abe novel Hei no Naka no Korinai Men-Men. Hei's name by itself means "wall".
