Gigantomachia/Relationships

All For One
Gigantomachia is totally and absolutely loyal to All For One. He was his bodyguard when All For One controlled the world from the shadows and said loyalty has not waned despite his downfall. For his part, All For One considers Gigantomachia an essential piece for Tomura Shigaraki and the resurgence of the League of Villains, so he hid him in the mountains so he would not fall with him.

This overwhelming loyalty is the only thing that controls the violent temperament of Gigantomachia. Just with a recording of his master’s voice sends him from a berserker rage into huddling beside the speaker like a child listening to his father. However, this also brings flaws, and is hard for Gigantomachia to follow orders from others that are not All For One.

Daruma Ujiko
Daruma is in charge of controlling and monitoring Gigantomachia after All For One decided to hide him after foreseeing his inevitable downfall. Daruma knows that Gigantomachia is extremely violent and extremely loyal to All For One, and therefor controls him with recordings of his master's voice on the radio that Gigantomachia carries on his neck. Daruma at times refers to Gigantomachia as "Machia". Daruma believes Gigantomachia is useful to Tomura's goals and refuses to lend his full support until Tomura gets Gigantomachia to submit.

Tomura Shigaraki
Due his loyalty to All For One, its difficult for Gigantomachia to believe that Tomura can competently follow their master's legacy, despite knowing that All For One chose Tomura as his successor. When he meets him and the League of Villains for the first time, he challenges them to a fight to see if they are worthy. However, he defeats them easily, being tremendously disappointed to see how weak they are.

This causes a crisis of faith in Gigantomachia, who tearfully bawling why his master chose someone too weak to uphold his legacy as his heir. Gigantomachia even states he wants to accepts Tomura but can't if he can't prove himself by defeating him. Daruma Ujiko is forced to intervene to stop Gigantomachia before he kills Tomura and his allies with his enormous strength.

For his part, Tomura is disappointed that the secret weapon of All For One is a beast he can not control. However after his conversation with Daruma, he knows that he must submit him to his will. Tomura proclaims to Gigantomachia that he is his new “king”. Amused by this attitude, Gigantomachia replies that a king should inspire dread, be admired and be strong.

For some time, they continue to fight with neither willing to change their viewpoint. Gigantomachia is amused Tomura can still fight but not above calling his attacks weak.
