Flect Turn/Synopsis

History
At a very young age, Flect Turn manifested a powerful Quirk that reflects everything that came near him, not only physical things, but also the feelings of those close to him. Because of it, he never felt his parent's love, much less a bond with friends or a lover. Flect tried by all means to control his powers, but unfortunately, Reflect was a Quirk that remains permanently active. Due to his inability to control it, Flect Turn fell into despair, blaming his Quirk for it, but not even suicide was a possible option for him.

At some point in his life, Flect became aware of the Quirk Singularity Doomsday Theory, and due to the misery his own Quirk caused him, he completely internalized the idea that Quirks would become so powerful and uncontrollable that they would lead to the destruction of mankind. As a result of this theory, Flect Turn developed a great hatred towards Quirks, considering them diseases, and a fervent desire to eradicate them in order to save the human race.

This would lead him to found Humarise, a cult that fanatically believes in the Quirk Doomsday Theory, attracting not only Quirkless people but Quirk users as well. Over time, and despite its bad reputation for being involved in various anti-Quirk incidents, Humarise would gain power and influence, spreading to other countries and building branches in twenty-five cities around the world.

It is at this time that Flect Turn begins to forge his plan to destroy Quirks, and to achieve this, a powerful weapon was necessary. To obtain it, he ordered his followers to kidnap scientists and forced them to develop the Trigger Bomb, a device that releases a large cloud of gas composed of Ideotrigger that would cause all Quirk users who consumed it to lose control of their powers and die because of it, sparing only the Quirkless. Under the threat that their families would be killed if they did not cooperate, the kidnapped scientists did as they were told, and after several years, they built several Trigger Bombs.

Flect Turn's plan is to detonate a Trigger Bomb in a major city in order to gather the top heroes around the world to the places where Humarise branches are located, then use the remaining Trigger Bombs to eradicate them all. Such a massacre would cause the world's society to collapse and fall into chaos, a time that would be used by Humarise to eradicate the remaining Quirk holders without opposition.

However, one of the kidnapped scientists, Eddie Soul, created a device containing a code to disable all the Trigger Bombs. Eddie gave the device to Alan Kay, another kidnapped scientist like him, who hid it in a secret compartment of a briefcase with a MicroSD where he reveals Flect Turn's secrets and how to activate the device. Eddie was executed when Flect Turn learned about the deactivation key, but Alan managed to remain hidden, posing as a devoted follower of Humarise, until he had a chance to escape.

Endeavor Agency Arc
Flect Turn, under a fake name, proceeds to hire smugglers to travel all over the world in order to steal chemicals needed to create the vast amounts of Ideotrigger for his plan. However, he learns that the most recent shipment from Japan had been disrupted due to being apprehended by a group of heroes. This does not deter him though, declaring that it is fine since they already have the amount they need for the plan, telling his people to prepare for "the salvation of humanity".
