[Transmigration, Invincible, Beyond Super, Fanfiction, Dragon Ball, Power Fantasy]

Sageet, a transmigrator who knows the entire story, is born in the Dragon Ball GT timeline. He thinks he can rest easy after dealing with the One-Star Dragon ahead of time, but discovers that the GT timeline he is in is separated from the main Dragon Ball Super timeline by fifty years. While GT Goku and Vegeta are still struggling to break through the threshold of Super Saiyan 4, Sageet's base power has already reached the realm of Super Saiyan 4. He tears open the dimensional barrier and forcibly enters the Dragon Ball Super timeline. On the timeline of Dragon Ball Super's first episode, Bulma's birthday party is underway, Goku is still training under heavy weights on King Kai's planet, and Beerus, God of Destruction, has just woken from a dream about the Super Saiyan God. The collision between the two timelines officially begins the moment Sageet steps out of the rift in time and space.
