From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Machine Mutants (マシン ミュータント, Mashin Myūtanto) are a type of artificial being introduced in Dragon Ball GT. They appear to be the creations of Dr. Mu, a Machine Mutant himself. Machine Mutants (and Machine Mutant technology in general) are fully mechanical beings with organic properties. They are able to mold, contort, and reshape like organic lifeforms. Machine Mutants also display the ability to absorb and integrate metallic and mechanical material into their own being and restructure themselves.
Humanoid Machine Mutants are easily identified by their eyes, which feature two lines going across their eyes and converging at the pupil. This gives their eyes a crosshair-like appearance.
Main article: Baby
Baby (ベビー, Bebii) was the parasitic creation and sole survivor of the Tuffle race that was destroyed by the Saiyans. As their last hope, the Tuffle King implanted his DNA into Baby, and launched Baby into space, hoping he would one day avenge them. As such, Baby carries an intense hatred for the Saiyans.
Baby created Mu to help him gain enough energy to reach his true potential, as well as to gather the Black Star Dragon Balls for recreating Planet Plant. After killing the damaged Mu and absorbing vast amounts of life force from all over the galaxy, Baby brainwashed every Earthling, along with the half-Saiyans, and took over Vegeta's body, in order to kill Goku, the last pure-blooded Saiyan, and recreate the universe in the name of Tuffles, with himself as their "God". In the end, Baby was forced out of Vegeta's body and fled, only to be hurled into the Sun by Super Saiyan 4 Goku.
 Dr. Mu
Main article: Dr. Mu
Mu (ミュー, Myū) was a brilliant scientist who desires nothing more than total control of the galaxy. Dr. Myuu masterminds the plot to build an ultimate machine mutant with enough power to see his sinister goal of control through to the end. To this end, he created a powerful enforcer named General Rilldo, and tried to gather the Black Star Dragon Balls to use them to complete his creation, Baby, and use it to take over the universe. However, Goku, Pan, and Trunks got past Rilldo and foiled Myuu's plans. Dr. Myuu escaped, but was killed when Baby burst out of his body. It was revealed then that Baby was actually the one that programmed Dr. Myuu, and not the other way around.
Mu later joins forces with Dr. Gero in Dragon Ball GT and creates another Android 17, who controls the original Artificial Human 17 and converges their powers together to set a rift between Earth and Hell. Hell's 17 and the two scientists escape, following which the two 17s eventually fuse together to become Super 17. Super 17 betrays and kills Gero thanks to Myuu's programming changes, then goes on to dominate the Z Fighters (including Super Saiyan 4 Goku thanks to his absorption field ability) that Myuu truly believes he can take over the universe, until Android 18 shows up and gets in his head by appealing to his sense of self.
Myuu, in anger at 18's apparent influence, orders Super 17 to destroy Goku and 18 with his Electric Hell Ball attack so as to show them "who he really is" and that he "can't be manipulated or controlled". However, 17 turns on Myuu, the very man who had been using him the entire time, and destroys him with the attack.
 General Rild
Main article: General Rild
Rild (リルド, Rirudo) was a Machine Mutant created by Mu in charge of security on his planet. When Goku, Pan, and Trunks arrive on the planet in search of the Black Star Dragon Balls, Rilldo sends the Mega Cannon Sigma to capture them. The Sigma Force are defeated by Goku and Trunks, leaving Rilldo to take care of the two by himself. Using his special beam that transmutes any object into metal, Rilldo captures Trunks, but is still defeated by Goku. After combining with the remaining scraps of the Sigma Force, Rilldo powers up to his Meta Rilldo form, forcing Goku to transform into a Super Saiyan to fight him properly. As Goku begins to gain the upper hand, Rilldo transforms again into Hyper Meta Rilldo to allow him to fuse with any metal on the planet and make him nearly invincible. Later, when Goku, Pan and Trunks escape from Mu's lab, they attempt to leave Planet M2 when Rilldo (possessed by Baby) tries to pull the ship down. He is killed when the trio use a Triple Kamehameha.
Rilldo returns later when the gateway to Hell is opened and fights against Gohan. He had the upper hand but is killed when Gohan is rescued by Majuub, Goten, and Trunks.
His name, Rilldo (rirudo) is an anagram of "drill" (doriru) in the original Japanese version, fitting him within the tool name scheme of the top Machine Mutants of Planet M2 (Rilldo's hand becomes a drill during one of his attacks to further play on this pun). FUNimation, however, chose to name him Rilldo instead.
Main article: Gill
Giru (ギル) was a Machine Mutant that accompanies Goku, Pan, and Trunks on their quest to find the Black Star Dragon Balls. His true name is T2006. The three first met him on a desert planet while he was on the brink of death. After eating the Dragon Radar for energy, he tried to escape from them, but was ultimately caught by Goku. After that, they found out that the radar was integrated into his software. Upon arriving on the Planet M2, he betrays them. Giru later has a change of heart so he and Trunks came up with a plan to make Myuu reveal his ultimate secret. The plan works and Giru and Trunks manage to save Goku and Pan from Mu. Giru then becomes part of the Black-Star Dragon Ball team again. (Giru never actually betrayed them. As they got closer to Planet M2 his programming fixed itself. He confessed everything to Trunks, and together they made a plan before ever touching down on Planet M2. Everything that happened up to Trunks' re-emergence was part of that plan.)
 Sigma Force
Main article: Sigma Force
Four robots that were part of Rilldo's forces on Planet M2. Each member possessed various beam and morphing capabilities found in high-level Machine Mutants. Together they had the ability to merge with Rilldo to make him even stronger and also the power to fuse themselves into one mechanized, the Sigma Force Cannon. The group consists of Nezi, Bizu, Ribet, and Natt. Their names are based on tools and construction hardware: "wrench", "vise", "rivet", and "nut" , respectively.
Main article: Lood
- Name pun: Doll (anagram)
- Seiyū: ??
- Voice actor: ??
Lood was a giant, baby doll-like Machine Mutant worshiped as a god on the planet named for it. The Machine Mutant was created by Mu, who mutated a single cell, creating a life-draining organism, and building a mechanical, doll-like frame around it. Luud possessed the power to turn others into dolls, and power itself with their life energy after the dolls were stored within a special container. The absorbed would then be manifested within its core, and stored as a power source. After creating it, Dr. Myu hired a con-man named Dolltaki to swindle his way into becoming a prophet to a planet of people, tricking them into worshiping Luud. After enough worshipers had been gathered, they would all be used as fuel to power Luud, with the objective being to power Luud to level 3; his maximum state of power. Later in the series, Mu reveals that Luud's purpose was to collect energy to be funneled to Baby, to power his restoration. Although catastrophically powerful, Luud was defeated when Pan (who had been absorbed, and trapped within Luud's core) and Goku simultaneously attacked his core nucleus from the inside and out (which was the only way to damage the core, and destroy Luud).
Main article: Mutchi
- Name pun: Whip (muchi)
- Seiyū: ??
- Voice actor: Justin Cook
Mutchi-motchi first appeared as the whip of Cardinal Mutchy Mutchy, a leader of the Lood Cult. Upon Cardinal Mutchy Mutchy's death, Mutchi-motchi revealed his true form as a mostly yellow alien-like Machine Mutant with long, spiked whips extending from the ends of his claw-like hands. These whips could cause any inanimate object they striked to seemingly come to life and attack Mutchi-motchi's opponent. This ranged from commanding wall-mounted swords to fly the the victim to causing hands to grow from the floor and restrain a person. Along with this, Mutchi-motchi was able to drain the life force of anyone wrapped in his whips, similar to the Ki-draining powers of Artificial Human No. 19, Artificial Human No. 20, and Super Artificial Human No. 17. Although he was a formidable opponent, he was eventually defeated by Trunks.
 Super Artificial Human No. 17
Main article: Super Artificial Human No. 17
Super Artificial Human No. 17 was originally meant to be Dr. Gero's "ultimate Artificial Human", becoming more powerful than ever before. After Gero and Mu united in Hell, they combined their technology to create Hell Fighter No. 17, which would combine with Artificial Human No. 17 to form the Super 17. After Mu revealed he had stolen Super 17's loyalty from Gero, Super 17 was no longer the "ultimate Artificial Human", but had been reborn as the "ultimate Machine Mutant" meant to surpass even Baby (without Vegeta). As a Machine Mutant, Super 17 lacked the crosshair-like eyes that all others had, but his energy absorbing field was a Machine Mutant ability that Mu had installed.
 Other Machine Mutants
Many Machine Mutants consisting of Gill-like robots with tails that were purple were quickly disposed of by Son Pan. They lived on Planet M2, and some attended General Rild's speech honoring T2006 a.k.a. Gill.
