|“||All monsters, and Godzilla, are called monsters because it cannot be defeated by people. To defeat what has surpassed human intellect is no longer within the category of human achievement. From the moment you decided that you'd defeat Godzilla, you were aspiring to become something that is no longer human, Haruo!||„|
|~ Galu-gu tries to convince Haruo Sakaki to give up his humanity to defeat Godzilla.|
Mulu-elu Galu-gu (ムルエル・ガルグ, Murueru Garugu) is the secondary antagonist of the GODZILLA anime trilogy. He begins as a supporting protagonist in the first entry, GODZILLA: Planet of the Monsters, and goes on to become the main antagonist of the second entry, GODZILLA: City on the Edge of Battle, along with Mechagodzilla. Galu-gu is a Lieutenant Colonel in the United Earth and a Technical Officer of the Bilusaludo race, one of the three humanoid races of the United Earth. Galu-gu was responsible for designing Mechagodzilla and is an ally of protagonist Haruo Sakaki in his quest to free the Earth from Godzilla 20,000 years into the future.
While Galu-gu initially acts as Haruo's friend and ally, he is actually a supremacist who believes the Bilusaludo are superior to other humanoid races and shuns concepts such as emotion and human nature in favor of cold logic. Along with the other Bilusaludo, he conspired to completely overtake the Earth with Nanometal using Mechagodzilla in order to create what he called "a world of perfect logic."
Galu-gu is a stern militaristic soldier who values strength and dedication in battle. As a technical officer, he is proficient with military technology and designed several weapons, most notably Mechagodzilla. He is friendly toward his allies Haruo Sakaki and Metphies, though he is a Bilusaludo supremacist who believes himself superior to members of the human and Exif races. He is also incredibly racist toward the Houtua, regarding them as "insects" and showing no qualms about exterminating them if necessary. Galu-gu believes humanity's unwillingness to become one with the Nanometal is a sign of weakness, and attempts to forcibly infect them with Nanometal anyway. Galu-gu has no respect for the concept of humanity and believes it makes people weak. He believes it is better to give up one's humanity in order to become part of something greater and live in a world of perfect logic. He is disappointed when Haruo disagrees with his philosophy, having hoped he was "different" from other humans, and tells Haruo that to defeat Godzilla is an ambition outside the realm of human achievement. Galu-gu's ultimate ambition is the complete Nanometalization of the Earth and everything on it, which he believes would create the perfectly logical world he dreams of. While he claims to reject emotion, Galu-gu perhaps hypocritically holds a grudge against Godzilla for killing his men and can be quick to anger if his authority is questioned.
GODZILLA: Planet of the Monsters
Galu-gu was a member of the Central Committee aboard the Aratrum, who debated whether or not to return to Earth after the ship's destination of Tau Ceti e proved uninhabitable. While in his quarters, Galu-gu was visited by Metphies, who asked for his opinions on Haruo Sakaki's anti-Godzilla plan. Galu-gu expressed doubt that Godzilla could be defeated even with the right strategy, but said he still found the plan interesting. He mocked the Exif for his race's failure to brainwash the earthlings with their religion, while Metphies likewise suggested that the Bilusaludo would have turned Mechagodzilla against humanity after defeating Godzilla. None of that mattered now, Galu-gu said, as they both failed to defeat Godzilla.
Galu-gu was later part of the Earth Landing Brigade which was sent to the radically-changed Earth to try and defeat Godzilla once more. Galu-gu designed a new weapon and oversaw its deployment in the Tanzawa Pass. He was disheartened when he learned Colonel Eliott Leland intended to withdraw from Earth after his men suffered an attack from Servum. However, the retreat was interrupted by Godzilla Filius, who killed Leland. Command fell to Metphies, who designated his authority to Haruo. Galu-gu cooperated with Haruo to execute his anti-Godzilla plan, which was successful in killing Godzilla Filius. When the original Godzilla, now grown into the 300 meter Godzilla Earth, arose, Galu-gu's fate was left unclear as the monster decimated the United Earth's forces.
GODZILLA: City on the Edge of Battle
When Haruo was captured by the Houtua tribe and brought to their underground village, he found that Galu-gu was still alive. Galu-gu believed the Houtua were mere primitives who intended to sacrifice them, and expressed willingness to exterminate them all if necessary. He and the others were brought into the central chamber of the village where the twin Houtua priestesses Miana and Maina addressed them telepathically. Galu-gu noted that he heard the Houtua's messages in the Bilusaludo mother tongue. The United Earth forces were released from the village, and began making their way through the forest in search of a downed Landing Ship. When the group was attacked by a flock of Servum, Galu-gu noticed the material the Houtua's arrowheads were made from. He asked Miana and Maina to show them their arrowheads, and recognized them as being made from Nanometal. He and Rilu-elu Belu-be returned to the Houtua village to investigate and found that the Houtua were harvesting large chunks of Nanometal from somewhere nearby to make their tools and weapons. They brought their findings to Haruo, explaining that if they could find the source of the Nanometal they could use it to defeat Godzilla.
The survivors made their way toward the former Mt. Fuji, where they discovered the source of the Nanometal: a replica of Mechagodzilla's production facility built entirely from Nanometal which Galu-gu dubbed Mechagodzilla City. After finding Mechagodzilla's intact head, the Bilusaludo reactivated its A.I. fully and took command of the City from a control room. Galu-gu and Haruo formed a plan to finally destroy Godzilla using the City and its vast supply of Nanometal. Godzilla would be lured to a capture point and trapped in liquid Nanometal, then flanking railguns mounted on the City's buildings would open fire on his dorsal fin. After the fin was destroyed, EMP Harpoons would be fired into Godzilla, overloading him with electromagnetic energy until he exploded. The plan was put into action, with Galu-gu overseeing it.
When a group of soldiers saw several Bilusaludo being absorbed by Nanometal inside the City, they brought this to Haruo's attention. To everyone's shock, Galu-gu explained that this was no mistake. The Bilusaludo were willingly giving up their individuality to become part of the City itself, which he considered a great honor. He and Haruo debated the ethics of this, but were forced to work together again when Godzilla began approaching the City. Haruo took command of one of the advanced Vulture mechs created by the City along with Belu-be and Yuko Tani to hold off Godzilla long enough for preparations to be completed. Galu-gu remained behind in the control room to finish the preparations for the plan. Godzilla was lured to a trap point where the ground was detonated, opening a tunnel leading directly to the City. When Godzilla reached the capture point, the tunnel was closed off and flooded with liquid Nanometal. The railguns opened fire on the immobilized Godzilla, destroying his dorsal fin before EMP Harpoons were fired into his back. Rather than explode, Godzilla converted the excess energy into heat to indirectly attack his foes. In response, Galu-gu triggered the City's Nanometal to fuse with everyone inside, much to the humans' horror. Most of the humans fled as Galu-gu and the Bilusaludo were taken by the Nanometal, prompting him to remark how weak humans are. However, he hoped Haruo would be different, and triggered the Nanometal inside the Vultures to fuse with their pilots. Haruo's body rejected the Nanometal thanks to the healing treatment he had received from Miana, while Yuko tried to eject from her Vulture as she resisted the fusion. Haruo caught Yuko's Vulture and was contacted by Metphies, who explained that once Mechagodzilla City defeated Godzilla, it would assimilate the entire Earth. Galu-gu angrily accused Metphies of betraying the Bilusaludo as Haruo flew to the control room to confront him. He ordered Galu-gu to end the Nanometal's encroachment, but Galu-gu responded by saying they had to become something no longer human to defeat Godzilla. Monsters were monsters, he said, because they could not be defeated by man. By deciding to fight Godzilla, Haruo aspired to become something not human. Haruo rejected Galu-gu's philosophy and opened fire on the control room, killing Galu-gu and destroying Mechagodzilla's head. With the Nanometal comprising the City deactivated, Godzilla resumed activity and destroyed the rest of Mechagodzilla City with his atomic breath.
