Gigantomachia (ギガントマキア Gigantomakia?) is a Villain associated with the League of Villains. He is one of All For One's faithful servants and his former bodyguard, cultivated to be of use to Tomura Shigaraki if anything were to happen to him.
Gigantomachia is an enormous individual, about the height of a large tree with a musclebound build. His brown hair is spiky and parts of his body appear to be jagged, much like rock. His teeth are prominently pointed, his lower canines protruding out of his mouth on either side.
Notably, he always carries a portable radio wherever he goes, sometimes even tying it to a rope and wearing it around his neck. He also sports a hooded cloak that he wears while in public.
Gigantomachia appears to be a polite person at first, but will quickly become impatient and aggressive towards those that are uncooperative with him. If someone manages to help him out, he will simply leave and avoid a confrontation.
He is also a faithful servant to All For One and questions Tomura Shigaraki's worthiness as his successor. His devotion and obedience to All For One are so great that simply hearing a recording of All For One's voice can calm him from breaking out into a blind rage. However, once he saw Tomura unlocking his true power and emerge victorious over Re-Destro, he truly acknowledged him. He even shed a tear of joy at him standing proud over his defeated foe.
Overall Abilities: Gigantomachia is an incredibly powerful force, serving years as All For One's personal bodyguard even before being modified with multiple Quirks. During a brief encounter with Gran Torino and several police officers, the behemoth forced the veteran hero to retreat while leaving a massive cavity in the side of a mountain. Come winter, Gigantomachia was able to take on the combined forces of the League of Villains' six remaining members (Tomura Shigaraki, Dabi, Himiko Toga, Spinner, Twice and Mr. Compress) with ease and defeat them, repeatedly. Even after battling him nonstop for a month, half of the League made little progress towards defeating Gigantomachia. In Tomura's own terms, Gigantomachia possesses "too much HP" which the disintegrating villain abuses to exhaust his opponents to submission.
- Immense Strength: Befitting his massive size and build, Gigantomachia has immense physical strength, easily cracking the side of a concrete building with his grip alone. During his confrontation with Gran Torino, Gigantomachia proved to be able to create an enormous hole in a mountainside, causing the hero to deem him "a walking disaster". With a simple hammer fist punch, he can strike the ground hard enough to pulverize the landscape around him and destroy nearby buildings. Using his tremendous brawn, Gigantomachia can pick up the equally gigantic Mt. Lady and toss her out of his way.
- Immense Speed: Despite his gargantuan bulk, Gigantomachia exhibits tremendous speed, enough to rip the trees out of the ground as he runs past them. He can run at least up to 100 kilometers (62.137 miles) per hour.
- Immense Durability: Beseeming his muscular physique, Gigantomachia body and skin are extraordinarily thick, taking virtually no damage from attacks. While he was unscathed from the League of Villains' consecutive onslaughts, Gigantomachia displayed minor annoyance at being bathed in Dabi's fire. Gigantomachia could fight his way through a large quantity of the Meta Liberation Army unharmed in spite of being flanked from all sides.
- Immense Stamina: Gigantomachia can imitate continuous assaults for a full 48 hours and 44 minutes without rest. But he can resume his onrushes after getting only three hours of sleep. Even after being subjected to a powerful sedative, he was able to remain at full power for quite some time. The sedative only started to take effect after he exhausted himself fighting his way through numerous Pro Heroes.
- Enhanced Senses: Gigantomachia has highly developed senses of hearing and smell. His senses are potent to where he cannot be caught by surprise, even whilst he slumbers. Gigantomachia olfactory perception is powerful enough to allow him to locate Tomura from miles away.
- Size Enhancement: Gigantomachia's chassis grows in battle as he fights, allowing him to eventually reach mastodonic proportions wherein he can fit an entire adult man within his hands and tower over buildings. He can grow to be at least 25 meters in height.
- Enhanced Breath: Due to Gigantomachia's increased size and strength, a single breath is enough to blow back several U.A. students and cause severe environmental damage.
Gigantomachia's only known weakness is that he can hardly think for himself. He requires orders from his master in order to carry out a task. The only known task that he can accomplish without being ordered is to come to his master's aid.
- Endurance: Gigantomachia's original Quirk allows him to convert his morale into physical energy and stamina.
- Pain Blocking: Gigantomachia's second Quirk makes him unable to detect any pain.
- Gigantification: Gigantomachia's third Quirk allows the bones in his body, such as his fingers and teeth, to grow to exponential lengths when agitated to increase his defense and attack power. This also causes them to jut out of his flesh unnaturally. Another incarnation of this Quirk is used by Mt. Lady.
- Dog: Gigantomachia's fourth Quirk provides him with a keen sense of smell and sight, similar to that of a dog's. Another incarnation of this Quirk is used by Hound Dog. 
- Energy Efficiency: Gigantomachia's fifth Quirk allows his body to be able to conserve nutrients and water, allowing him to process without much sleep.
- Tough Muscle: Gigantomachia's sixth Quirk allows his muscles to harden to exceptional levels.
- Mole: Gigantomachia's seventh Quirk allows him to grow mole-like claws from his fingers to help him dig through the Earth, as well as tear through obstacles, such as buildings.
