“Let’s go over the second part of the speech, shall we. You useless old fool. It was Hego Damask as Darth Plagueis who came to Naboo, determined to suck the planet dry of plasma and set the Trade Federation up as its overseers. It was Hego Damask as Plagueis who then set his sights on a seemingly confused young man and, with meticulous skill, manipulated him into committing patricide, matricide, fratricide. Darth Plagueis who took him as an apprentice, sharing some of his knowledge but withholding his most powerful secrets, denying the apprentice his wishes as a means of controlling him, instilling in him a sense of murderous rage, and turning him to the dark side. It was Plagueis who criticized the early efforts of his apprentice, and who once choked him in a demonstration of his superiority. Plagueis, who denigrated him in private for hiring an inept assassin to carry out the murder of Senator Kim—and yet who allowed himself to be tricked by the Gran and nearly killed by mercenaries. Plagueis, who turned away from the Grand Plan to focus entirely on himself, in an egotistical quest for immortality.“

The following has spoilers from recent chapters of My Hero Academia. You have been warned.
It has finally happened! After so much struggle, Tomura Shigaraki has freed himself from the control of All For One’s vestige. He is now in complete control of his own body once again. In addition to being in control of his augmented body, Shigaraki is now in control of the All For One quirk and all the quirks that are within it.
It turns out that All For One’s vestige fusing with Shigaraki’s was an illusion. What was preventing the fusion from truly succeeding was the fact that Shigaraki was keeping the vestige of Tenko Shimura as far away from All For One as possible. Tenko’s vestige represents Shigaraki’s origin as a supervillain. As long as his “origin” is kept out of All For One’s reach, Shigaraki was able to gradually regain his personality and body bit by bit without All For One noticing. By the time All For One realized what was going on, it was too late. Like a butterfly emerging from its cocoon, Shigaraki’s vestige burst out of All For One’s vestige in a mass of writhing fingers, more powerful than ever before.
When Shigaraki first gained the All For One quirk, All For One’s vestige acted like a parasite trying to possess and assimilate Shigaraki’s vestige. Then, in a twisted sense of irony, Shigaraki became a parasite himself. After being fused to All For One’s vestige, Shigaraki gestated and grew within until he burst out like a botfly larva eating its way out of its host’s flesh.
Like the Sith Rule of Two, the apprentice has surpassed and usurped the master! Shigaraki overthrew All For One as the demon lord of darkness and king of the underworld. Despite All For One’s attempts to possess him, Shigaraki declared that his heart will never surrender. It took some time, but Shigaraki’s indomitable willpower became so great that he completely overwhelmed All For One’s. All For One has done it! He succeeded in creating a supervillain who was greater than him! Tomura Shigaraki’s transformation as a supervillain is finally complete!
