Tomoyasu Chikazoku/Synopsis

Meta Liberation Army Arc
Tomoyasu is present at the meeting of the Meta Liberation Army executives. When Re-Destro shows surprise that Giran has been brought to them so quickly, Tomoyasu reminds him that he was the one who gave the order to do so and that his words are those of Destro, so he should choose them carefully. Although Giran has destroyed his client data, Tomoyasu is able to restore it, allowing the Army to figure out the identities and locations of the League of Villains members.

As the Revival Celebration proceeds, Tomoyasu expresses disappointment that Curious entered the front lines and was defeated, lamenting that the footage she collected is now unusable and that Curious should have used Himiko to play up the tragic heroine angle. When Giran asks about the footage, Tomoyasu derides his inability to understand what they're discussing before explaining that they have security cameras installed throughout the town to record the battle between the Army and the League, allowing them to spin the conflict into heroes protecting the town from villains.

Tomoyasu continues to monitor the battle, waiting for Twice to encounter Himiko. He sends out his puppets to kill Himiko and retrieve Twice for the Army so that they can use his Quirk to create clones of Re-Destro in case of their leader's death. Knowing that Twice was almost killed by clones of himself, Tomoyasu transforms his puppets into copies of Twice to traumatize him and make him easier to capture. He orders a pair of puppets to hold down Twice while the rest restrain Himiko and begin twisting her neck until it snaps. Meanwhile, he taunts Giran by telling him he obtained the information about Twice's psychological disorder from the client data Giran failed to erase and that Himiko will soon be dead while Twice will belong to the Liberation Army.

Twice manages to break free of the puppets' grasp and rushes to Himiko to rescue her. Tomoyasu, surprised, muses that he had expected Twice to either run away or continue cowering, noting that Himiko and Twice have a stronger bond than anticipated. Nevertheless, he remains composed and orders his puppets to beat Twice into submission before having them grab his arms and break them. As Twice screams from the pain, Tomoyasu threatens to break his legs next if he refuses to stop his futile struggling.

Observing that Himiko has regained consciousness, Tomoyasu casually mentions that he will have to adjust the power output of his puppets to break her neck. However, Twice's survival in the face of his injuries inadvertently allows him to overcome his fear of being a clone and fight back against Tomoyasu by generating a group of his own duplicates, causing the latter to grit his teeth in frustration.

Re-Destro remarks that it is a rare occurrence for Tomoyasu to fail, which Tomoyasu, bearing a manic expression on his face, refutes by saying he has only failed once in his entire career and that he simply needs to take additional measures to rectify the situation. This results in Tomoyasu entering the front lines, creating more puppets with his quirk and leading them while approaching where Twice and Toga are, ranting Jin's name and constantly denying that he has failed.

However, he has no chance to fight Jin, because at that time Gigantomachia arrives in the city destroying everything in its path. A panicked Skeptic calls Re-Destro to try to warn him about the League's monster that is heading towards his position, sweeping everything and everyone in his path. At those moments, Re-Destro is too busy fighting against Tomura Shigaraki.

The fight is over when Tomura unleashes the full power of his Quirk, destroying much of Deika city and leaving Rikiya Yotsubashi legless. Tomoyasu expresses concern for Re-Destro who admits defeat and lends the MLA's strength to the League of Villains.. In the following days, Skeptic and his puppets were editing and manipulating the footage of the battle and destruction of Deika City to make it look like a terrorist attack perpetrated by a group of twenty villains with a "grudge against heroes", with the inhabitants of the city fighting against them.

One week later after the Revival Party, the League of Villains dines on sushi while waiting for a meeting. Skeptic and Trumpet enter to lead to the League to the meeting. Skeptic is annoyed at the League's slow response and complains that it was the Meta Liberation Army's money that paid for the sushi, medical treatments, Himiko's coat, and doctored videos. Trumpet tells Skeptic to stop. The group goes down to the fourth level of the Army headquarters basement where Re-Destro holds a ceremony to announce the merging of the League of Villains merge with the Meta Liberation Army, with Tomura as the leader of the new "Paranormal Liberation Front", with the prominent members of both groups as his Lieutenants.

Endeavor Agency Arc
At the Paranormal Liberation Front base, Tomoyasu overhears Slidin' Go's words about being in a higher rank than Hawks and quickly puts him in his place, bluntly reminding him that he is just a low-ranking hero. Thanks to his position, Hawks has access to the Hero's central information network. For this reason, Skeptic planted twenty microdevices on Hawks, allowing him to have access to all kinds of information, proclaiming that nothing the heroes do is hidden from him. Skeptic was later at a meeting with the other lieutenants, during which Hawks reported that Heroes aren't aware of the Front's existence and Skeptic remarks on how Endeavor took upon three trainees. Hawks left the room and the lieutenants continued discussing a plan that would require four months to put in motion.

Paranormal Liberation War Arc
He was seen panicking when the heroes were attacking and begins searching for Twice, blaming him for what's happening. Although he acknowledges that it was possible for Hawks to deceive him despite having kept such a sharp eye on him, he insists that Twice is still at fault. When the villa cracks open, he shouts, canceling the conference of the lieutenants, while ordering violet, black and brown regiments to engage the heroes, but directing carmine to the assembly hall. The regiments soon attack the heroes, while Tomoyasu retreats to the villa.

Later, when Tomura awoke and ordered Gigntomachia to gather the PLF members and bring them to him, Skeptic was seen riding on the behemoth's back. He then complained that he was the only non-League lieutenant on Gigantomachia's back and that they should protect Re-Destro, to which Dabi replied that he should stay put because heroes still haven't noticed them. However, the students manage to pin down Gigantomachia, as the lieutenants on his back were holding him back. While the giant's lying on the ground, Skeptic notices the heroes start swarming his back.

Gigantomachia stands up, sending the heroes falling to their death, and realizes he should take out the heroes before he goes to Jaku. He then is attacked by the heroes flying on Majestic's rings, after Red Riot threw the jar with the sedative into his mouth. Gigantomachia defeats all the heroes and starts running towards Tomura's location, with the lieutenants on his back, as the rest of the PLF follows behind.

The news of Endeavor fighting Shigaraki at Jaku reaches Dabi, who tells Skeptic to prepare as they're going to tear down the hero society. The Heroes, however, start regrouping and Tomoyasu notices that using his Satellite Image. He says that there are not as many heroes as at the villa, but still a formidable number. He starts forming a strategy to counter them, but Mr. Compress tells him to zoom in on Uravity and Froppy, which catches Himiko's attention and she rushes towards them.

When Gigantomachia finally arrives at the battlefield, Tomoyasu broadcasts Dabi's pre recorded video, in which he reveals his past, how Endeavor abused him and drove him to the path of villainy. Skeptic managed to edit Dabi's pre-recorded message as well as the footage of Hawks stabbing Twice in the back to make Hawks look like a cold-blooded killer as they were all riding on Gigantomachia. He proudly announces that and sarcastically orders Dabi to bow down to his skills. Before Dabi can kill Endeavor, though, Best Jeanist appears on the battlefield and uses his Quirk to restrain the Lieutenants and Gigantomachia, with Skeptic getting trapped on the giant by the wires.

Mr. Compress then starts making his escape, after Gigantomachia has started feeling the effects of the sedative U.A. Students injected. As he's making his way on the giant villain, Skeptic notices him and pleads for rescue, which Compress does, by compressing him and continuing getting to Gigantomachia's top. Mr. Compress then puts the marble containing Skeptic and Dabi in Spinner's scarf, as he's dragged out of the battlefield by the Near High-End Nomu, after Tomura woke up and his body was taken over by All For One.

That same night, after All For One assaulted Tartarus and freed its prisoners, the villain asks him, Dabi and Spinner to watch over Tomura's body, as he needs to rest to recover from the wounds suffered throughout the day.
