Byte is distinguished by his hefty red armor, with yellow, blue, and grey decals inspired by East Asian spiritualism.

In the Games

Mega Man X3

Sprite from Mega Man X3.

In Mega Man X3, Byte first shows himself in the cutscene that plays after the player destroys two Maverick bosses. Dr. Doppler orders Bit and Byte to capture X for him, preferably alive, and they depart.

After this cutscene, Byte may randomly appear as a mid-boss in the sixth, seventh, or eighth Maverick stage X visits. Defeating Byte normally causes him to retreat and stop appearing. However, if the player lands the final blow using his weakness (Tornado Fang or Ray Splasher), Byte explodes upon his defeat and is destroyed. This stops him from appearing in Doppler Stage A later in the game.

If Byte retreats, he returns at the end of Doppler Stage A. Regardless of whether or not Bit was destroyed, Byte transforms his body into Godkarmachine O Inary, having been upgraded by Dr. Doppler to defeat X. Once the player destroys Godkarmachine, Byte perishes.

Mega Man X DiVE

In Mega Man X DiVE, Byte appears as several Maverick Data bosses. In the game's Story mode, he is fought as a boss twice. The first time is his base form in Chapter 11 in Oil Field 11-6, and his defeat unlocks the Chip for Overpower. The second time is him wielding the new Gravity Gear technology, in Chapter 15 in Super-Electromagnetic Lab Stage 15-6.

A Valentine's Day-themed variant of Byte, called Byte VD, appeared as a boss in the Valentine's Day 2022 Event, "Idol! Music! Valentines Day!".

Mega Man X Legacy Collection

MMX3 - Nightmare Police Art.png The Nightmare Police
Bit & Byte
A pair of high-spec law enforcement Reploids designed by Dr. Doppler to maintain security in Dopple Town. They have been designed with all the best qualities of the world's top Reploids, so their performance exceeds that of the average Reploid.
Dr. Doppler's madness has spread to Bit and Byte, and they have joined him in the war against humanity. They can be found wherever Doppler's forces have captured territory, relaying the doctor's orders to the Reploids under their command.

Mega Man X DiVE

MMXD - Byte Art.png
One of the members of the Nightmare Police designed by Dr. Doppler. He is the opposite of Bit who specializes in incredible speed, and is a combat-focused robot with overwhelming power. He attacks by throwing magnetic mines that impede movement and destroys his enemies with brute force.
MMXD - Byte Art.png
Byte (Gravity Gear)
One of the members of the Nightmare Police designed by Dr. Doppler, and this one features overwhelming emphasis on raw power. Apart from his standard weapon of magnetic mines, he has also been equipped with a black hole generating device that can pull or push targets.


  • Byte's design is heavily inspired by East Asian culture and religions, including Shinto and Hinduism.
    • His original Japanese name, Mandarela BB, is derived from the Sanskrit "mandala", a concentric diagram with spiritual significance in both Buddhism and Hinduism.
    • Much of his design seems inspired by the Nio in Buddhism, the muscular guardians of Buddha. This is evident in his scowling face, his loincloth-like faulds, the hagoromo-like ring over his shoulders, and his muscular build with a prominent belly.
    • His weaknesses may reference one of the tales of how the Nio came into the service of Buddha; one tale held that the Nio were originally a duo of thieves who brutally robbed anyone they came across, until they were brought to penance upon encountering the light and compassion (bringing to mind Ray Splasher) of Buddha.
