Hey Ho[1] (ヘイ・ホウ[2] Hei hō?, lit. "Hei Hou") is a character that appears in the Sonic the Hedgehog series. It is a robot created by Dr. Robotnik, who used it during the second part of the Angel Island incident.


Hey Ho is a robot that resembles the upper body of a human body. It has thrusters 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. Lastly, Hey Ho's head itself is shaped like a dark cylinder with brown eyes.


Sonic the Hedgehog 3 & Knuckles

In Sonic & Knuckles, and the lock-on game Sonic the Hedgehog 3 & Knuckles, Hey Ho attacked Sonic and Tails while the duo was in Mushroom Hill Zone. However, the robot was defeated by the heroes.

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

Other game appearances

Sonic Jam (

In the version of Sonic Jam, Hey Ho is featured as the first boss in the "Sonic & Knuckles" section. The boss is much easier than it was in Sonic & Knuckles, as there is only one tree to the right, and Hey Ho itself is very slow, chopping at a rate of about one time every thirty seconds. In addition, the boss was placed lower (due to the's small screen), making it possible to attack it by simply jumping into it.

Powers and abilities

Thanks to its design, Hey Ho is capable of flight.


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


Hey Ho is the boss of Mushroom Hill Zone Act 1 in Sonic & Knuckles and Sonic the Hedgehog 3 & Knuckles, as well as the first boss overall in the former. In Sonic the Hedgehog 3 & Knuckles, it is the fourteenth boss overall in Sonic and Tails' stories and the thirteenth boss in Knuckles' story. In Sonic & Knuckles, it is fought by Sonic or Knuckles, while in Sonic the Hedgehog 3 & Knuckles, it can also be fought by Tails either alone or as Sonic's partner.

Boss guide

Hey Ho will fly over to the rightmost tree of the screen and will use an axe to chop it down, sending the resulting chunks of wood flying horizontally to the left. 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 to the right once it comes loose. It will then repeat its attack pattern more.

If fighting Hey Ho as Knuckles, it has a more difficult attack pattern. The wood chunks knocked by Hey Ho's axe may also bounce along the ground a few times instead of flying horizontally. After reaching the ground, Hey Ho will fire its head, which flies off to target Knuckles' location before returning to Hey Ho's body. It will then travel in an arc path in attempt to hit Knuckles once more before moving on to the next tree to repeat its attack pattern.

The player can land a Spin Jump to hit the boss though touching the fire exhausting from Hey Ho will damage the player unless they have a Flame Shield.
