Hei Hou (ヘイ・ホウ[1] Hei hō?) is a character that appears in the Sonic the Hedgehog series. It is a robot that was created by Dr. Robotnik, who used it during the second part of the Angel Island incident.


Hei Hou is a robot that resembles the upper body of a human body. It has motors instead of legs and possesses black, sliver, and golden armor. It has round shoulders, white glove-like hands with four fingers, thin wrists, golden wrist and shoulder cuffs with studs on them, and two cylinders on its back as a jetpack. Also, its head itself is shaped like a cylinder..


Sonic the Hedgehog 3 & Knuckles

In Sonic & Knuckles, and its lock-on version Sonic the Hedgehog 3 & Knuckles, Hei Hou attacked Sonic and Tails while the duo was in Mushroom Hill Zone. However, the robot was defeated by the heroes.

Later, a re-built Hei Hou would attack Knuckles in Mushroom Hill Zone. Like before though, it was destroyed by the echidna.

Other game appearances

Sonic Jam (

In Sonic Jam for, this boss is featured as one of the bosses in the Sonic & Knuckles game. It is extremely easy now as there is only one tree (to the right), and the boss itself is very slow and chops at a rate of about one time every thirty seconds. In addition, the boss was placed lower so it could be visible on the screen, making it possible to simply jump at it.

Powers and abilities

Thanks to its design, Hei Hou is capable of flight.


Hei Hou wields a golden axe that works as its main weapon. With it, it can cut down trees.

Other game appearances

Sonic Jam (

In Sonic Jam (, Hei Hou appears as one of the bosses in Mushroom Hill Zone.


Hei Hou is the sub-boss of Mushroom Hill Zone in Sonic & Knuckles and Sonic the Hedgehog 3 & Knuckles, as well as the first or fourteenth boss overall, respectively. In Sonic & Knuckles, it is battled by Sonic or Knuckles, while in Sonic the Hedgehog 3 & Knuckles, it can also be battled with Tails either alone or as Sonic's parther.

Boss guide

Hei Hou uses an axe to chop down trees, sending the resulting chunks of wood flying towards the player. If fighting it as Sonic and/or Tails, it gets its axe jammed in the bottom piece of the tree it was chopping and struggles to pull it free, only to go flying backwards once it comes loose. If Knuckles is the one battling it, it will use a slightly different attack pattern where the wood chunks will bounce, and its head will be used to attack, flying off to hit Knuckles before returning to Hei Hou's body so it can move on to the next tree.
