MASSIVE SECRET THAT TORIYAMA (Rest in peace) AND TOYOTARO HID FROM US!!!

Fused Zamasu used Multiform to create infinite clones of himself, which he must have got from his Goku Black half because that delta male cuck Future Zamasu could never have learned it. Goku Black must have got Multiform from being inside Goku's body because he's a beta male cuck that couldn't have ever learned it on his own. This means that Goku must have learned it at some point, and the only point in the timeline that he could have learned it was when he was betrayed and trapped in the Hyperbolic Time Chamber for 420 nonillion years. The only person who could have taught it to Goku is Tien because he's the only other person who knows it. This means that Tien has a gigachad version of Instant Transmission that allows him to teleport anywhere in the multiverse, which he used to teleport into the Time Chamber and teach Goku Multiform, then he used the psychic abilities that he learned from Chiaotzu and King Kai to erase Goku's memories of learning Multiform because he didn't want Goku using it. Tien did this because he knew that Zamasu was going to steal Goku's body because his third eye lets him see the future, and since Goku's body had used Multiform before, Goku Black would have the ability to learn it, and Tien knew that Goku Black would be able to create a stronger version of Multiform that creates infinite clones. He wanted Goku Black to use this against Goku, Vegeta, and Trunks for three reasons. He wanted revenge on Goku for not killing Vegeta, he wanted revenge on Vegeta for killing him and his friends, and he wanted revenge on Trunks for making him lose aura in the Bojack movie. Since the Zamasus failed to kill Goku and the boys, Tien has chosen to use Frieza as his new puppet. He purposefully got eliminated in the ToP early on so that Frieza would have the chance to get revived, and then discover the Time Chamber and train in it for 10 years. While Frieza was in the Time Chamber, Tien teleported in there to give Frieza a potion that gave him a new transformation, but nerfed his potential. That way Frieza would be strong enough to body Goku, Vegeta, and everybody else, but weak enough to where Tien could still control him with his psychic abilities. This is why Tien is gonna be the twist villain of the next arc.
