This page is dedicated solely for the quirks in Shotoku's possession.
All for One: This quirk allows it's user to steal other people's Quirks, leaving them Quirkless, and wield their Quirks as his own. All For One can also distribute stolen Quirks to other people.
Rivet Stab: Rivet Stab allows its user to generate black tendrils that have red prominent cracked lines that extend from the users' fingers, although they can also emerge from other parts of the body such as the spine.
Forced Quirk Activation: Forced Quirk Activation allows the user to forcefully activate someone's Quirk against their will. Whether the target is conscious or not, the Quirk will work without fail, thus giving the user a method to use their allies' Quirks without having to worry about their state.
Muscle Augmentation: Muscle Augmentation is a Quirk that gives its user the ability to amplify, and to a degree, manipulate their muscles, granting a significant increase in strength, speed, and durability. When using this Quirk, muscle fibers can be enlarged to the point where they can no longer be contained by the user's skin.
Warping: This Quirk allows the user to produce a black ooze-like liquid from other people's mouths. The black liquid then envelops the person's entire body and acts as a warping portal, vanishing along with the target before reappearing at a different location. It's possible to create separate portals to warp multiple people all at once. The black liquid apparently has a horrid smell. Warping utilizes specific people as a destination, unlike Warp Gate of Kurogiri, which uses coordinates
Strength Enhancer: The unnamed Quirk seemingly enhances one's physical strength. Shotoku possess several quirks of this nature.
Unnamed Lie Detecting Quirk: This Quirk allows one to sense whether a person is lying or if they possess any semblance of ill will. The Quirk got stronger through the mixing of various other Quirks throughout the years. The Quirk was stolen from Naomasa Tsukauchi's ancestor.
Mind Program: Through touching one's head, this quirk leaves behind a 'program that would take root and affect the mind of the victim. 'Programs' that are too contracting with the mind of the victim will cause deterioration of victim's mental abilities and capacities. Stolen from Edgar Cizko.
