Super Dragon Ball Heroes

Something crash lands on Earth. Everyone goes home from the Super Space-Time Tournament, but Chronoa, Vegeta, Gohan, Piccolo, and Xeno Trunks wait for Goku to wake up. Chronoa attempts to send them to Earth, but it is gone. Shocked, they go to the planet of King Kai, but are greeted by Majin Ozotto, who explains that he ate King Kai and his companions, plus everyone and everything on Earth. Now he aims to eat more gods and attacks Chronoa. The others defend her and fight him with Goku and Vegeta using Super Saiyan Blue, Xeno Trunks using Super Saiyan God, and Gohan using Mystic Form, but he quickly absorbs Piccolo and Gohan. When they damage him, he reveals he gained regeneration from absorbing Buu, plus his detached parts can shapeshift into anyone he absorbed, which he demonstrates with Android 17 and 18. He merges with his duplicates and his power skyrockets. Realizing the battle is hopeless, Chronoa teleports herself, Goku, Vegeta, and Xeno Trunks away.

Chronoa explains that Majin Ozotto is a notorious criminal the Time Patrol had been tracking. Ozotto attacks the Elder Kai, having already absorbed Supreme Kai and Kibito, but is interrupted by Xeno Goku and Vegeta. He transforms into Baby and battles them, then has duplicates transform into Frieza and Perfect Cell to battle them. Chronoa's group goes to Namek, but all the Namekians have already been absorbed. They find another Ozotto preparing to consume the planet and challenge him. After Xeno Goku and Vegeta defeat the duplicates, the intrigued Ozottos reveal their desire to absorb everyone to have all their powers and invites both groups to the Ozotto Mansion. They teleport away, leaving invitation cards behind.

Joined by Xeno Goku and Vegeta, the group goes to the Ozotto Mansion, but makes Chronoa stay behind to not risk her. They blast the mansion, but it is unaffected. Ozotto's voice challenges them to split up and enter 5 different entrances. If they find and defeat the real Ozotto, everyone he ate will be freed. Goku finds and battles an Ozotto duplicate using Ultra Instinct; the duplicate changes to Turles, Bojack, and Meta Cooler and they are evenly matched. Vegeta finds a duplicate who changes to Super Janemba's form. After giving Vegeta a beating, the duplicate says he is too weak to be a meal and would rather eat Goku. Enraged, Vegeta uses Super Saiyan Blue Evolved and blasts him with Final Flash. Meanwhile, Gohan wakes up in a pod and finds Goten, Trunks, and others in pods. As he struggles to break free, Ozotto taunts him and explains that they are all inside his body.

Ozotto taunts Gohan by hurting Goten and Trunks, but when he threatens Videl, Gohan explodes with rage, breaks free from his pod, and attacks Ozotto. After defeating their opponents, Xeno Trunks, Xeno Goku, and Xeno Vegeta regroup and realize they cannot contact Chronoa. Goku and Vegeta break into the area where Gohan and Ozotto are fighting, but Ozotto uses the distraction to reabsorb Gohan, and his power skyrockets. With little options, Goku and Vegeta use the Potara to fuse into Vegito. Vegito uses Super Saiyan Blue and obliterates Ozotto, causing a heavily injured Gohan to reappear, just before he separates. As Goku and Vegeta check on Gohan, he warns them that they are inside Ozotto. As he says this, the entire mansion morphs into a giant Ozotto. Meanwhile, Xeno Trunks, Goku, and Vegeta are threatened by several duplicates of past villains.

Ozoth's mansion was the giant Ozoth himself! Goku and the others are confused by this shocking truth. Communication with the Supreme Kai of Time was cut off, The Xeno warriors rush to get there, but...!?

Goku and his friends successfully escape from Ozoth's mansion. Will they be able to thwart Ozot's ambitions? The final battle against the evil invaders begins now!
