"Bumo... Bumomomo! Bumomo Bumomomomo Bumo!"
―Yellow Devil, Mega Man Powered Up

Yellow Devil (イエローデビル Ierō Debiru), also known as Rock Monster or Yellow Demon, is a gigantic robot, the first combat robot created by Doctor Albert W. Wily, originally appearing as a fortress boss in the first Mega Man game. Its body consists of yellow goo-like shape-memory parts that can dismantle and fly across the screen to attack his enemies. Its only weak point is its red eye.

Video game appearances

Mega Man

The Yellow Devil can be very difficult to defeat due to its complicated attack pattern, being able to split into 19 parts that move in a set pattern. When assembled, the red eye that is its weak spot appears and fires a projectile, giving Mega Man a chance to hit the eye once or twice before disassembling again. His weakness is the Thunder Beam.

Mega Man Powered Up

In the remake of the original game, it is revealed that the Yellow Devil can talk, but the only thing it can say is "Bumo", which it says in various ways in order to form its own language. Cut Man attempts to speak to it, but without much success as it only seemed to insult the monster. Ice Man appears to understand what the Yellow Devil is saying, however, and says that even though the Yellow Devil has a mission, he has his own mission, too. Oil Man just copies its "bumo"s. Bomb Man doesn't understand what he says and tells him to speak in a "language that can be understood".

Its attack pattern in New Style is different from the original. On Easy Mode, it will just stand in one place and reveal its eye to shoot energy spheres. On Normal, it splits into parts like the original game, but in 15 parts with a different pattern. The same attack pattern is repeated on Hard, but it can also fire a laser beam at the player either from the ground or the wall. To avoid the ground laser, the player has to stand near the wall and jump at the correct time. To dodge the wall laser, the player just has to run near him. If the player stands near it, it will sometimes try to crush the player with its hand. It is weak to the Fire Storm.

Mega Man: The Power Battle

Yellow Devil appears as the penultimate boss of the "Mega Man 1~2" and "Mega Man 3~6" courses. In the "Mega Man 1~2" course, it jumps back and forth and sometimes takes on a round form and attack with a laser. It also attacks by splitting into nine parts that fly across the room, throwing a cube-shaped part of its body that bounces across the room, slamming enemies with its hand to pull the target into its body and launch them at high speed, and blasting its upper body into four fists diagonally to punch foes. Its weakness is the Super Arm.

In the "Mega Man 3~6" course, the Devil only jumps back and forth. After taking a small amount of damage, the Yellow Devil splits into three smaller versions of itself with horns. One of the miniatures will stay the ground, jumping around and firing three small projectiles or splitting in three parts. The other two miniatures will walk around the ceiling and attack by releasing three large energy spheres. After the small version in the ground takes some damage, it will jump to the ceiling and change places with the other miniatures. After all three receive enough damage, the Yellow Devil will reform and jump around the room. It is weak to Gyro Attack.

Mega Man 2: The Power Fighters

Yellow Devil is the penultimate boss of "Rescue Roll!" course. Its attack pattern is similar to the "Mega Man 1~2" course from The Power Battle, except that its splitting attack changed and the four-way fist blast was removed. It can walk and defend against attacks in this game. It is weak to Thunder Beam.

Mega Man: Battle & Chase

Yellow Devil is one of three enemy racers (the others being a 4 Roader and Joe), forcing itself inside a blue vehicle to be able to race. The heavyweight vehicle has no weapons, but its rams are powerful. There is also a secret boss recolor of him called Black Yellow Devil.

Super Smash Bros. for Nintendo 3DS / Wii U

The Yellow Devil appears as the main stage hazard in the Wily Castle stage from the Super Smash Bros. franchise, being deployed from the castle itself in the background. It behaves and fights similarly to its 8-bit counterpart, firing multiple blasts of energy from its single eye and splitting up into 20 parts to reform on the other side. Its pattern is the same as in Mega Man, but with one extra part between the 6th and 7th part, which is actually the empty space between the legs. Players can choose to fight it by attacking the exposed eye, its only weak spot. If defeated, the Yellow Devil will release a highly damaging explosion, which will count as an attack for the player who dealt the final blow.

Other appearances

  • Yellow Devil has a cameo appearance in the opening cutscene of Mega Man 8.
  • The Yellow Devil was shown in the first trailer of Rockman Online, but the game's cancellation as well as lack of footage featuring it makes it impossible to determine where it was intended to appear and what role he was supposed to play.
  • Yellow Devil could be obtained in an event from Yuusha no Kuse ni Konamaiki da DASH!, where it is said to be made of liquid metal.

Other media

Mega Man (Archie Comics)

The Yellow Devil appears in the first issue when Mega Man is entering Wily's fortress. However, during the fight, the scene cuts to the (chronological) start of the story. The battle's conclusion is shown in the fourth issue. Mega Man destroys the Devil with the Mega Buster as he doesn't want to use the weapons copied from the Robot Masters.

Despite its defeat, the concept of Yellow Devil would inspire further evil creations, including the Chaos Devil and the Ra Devil. The former was created by combining Yellow Devil technology with the creature Chaos in a cooperative effort between Wily and Dr. Eggman, Chaos being a native of Eggman's world. The Ra Devil was created as an improvement upon Wily's design by Ra Moon, who sought to turn Wily's own work against him as the doctor had attempted to do by creating Ra Thor. Mega Man later faced an improved version when attacking Dr. Wily's newest castle.

Short Circuits

Prior to the Worlds Collide crossover event, Yellow Devil did not make an appearance in the Short Circuits series. During the crossover, however, it did appear in one of the Off Panel strips of the Sonic the Hedgehog series, in which it is seen talking to Tikal the Echidna, who attempts to convince it that violence is not the answer to its problems. It later returned in Worlds Unite in Sonic Universe #77's Off Panel strip, crammed in with various characters from Sonic the Hedgehog/Sonic Universe, Sonic Boom, Mega Man, and Mega Man X.

Mega Man Megamix

Yellow Devil is the large robot who stands guard within the main control room of Wily's fortress. Its body parts are composed of an organic ferromagnetic polymer gel, and each part is controlled by a nucleus-like core. Changes in the magnetic field allow it to take on the distinctive Yellow Devil form. What appears to be its eye is the main core that controls its entire body. Wily believed Yellow Devil to be his greatest creation ever, but due to the fact that Yellow Devil's core could be disrupted by a strong electromagnetic pulse, the Thunder Beam proved to be his ultimate weakness. All the Yellow Devil can say is the letter "W".

After the defeat of Doctor Thomas Light's six Robot Masters in the story "The Birth of Mega Man", Yellow Devil holds Mega Man hostage as he meets Dr. Wily. Wily tries to convince Mega Man to join him, but as he refuses, he orders Yellow Devil to crush him. Mega Man manages to escape Yellow Devil's grip by using Guts Man's strength, breaking its arm, and then finish it off with a Thunder Beam.
