Seven Years later a small child with a monkey tail runs out of the training room with bruises all over his body. Bulma walks behind him with Nero. "Our son is gonna grow up to be one of the strongest in this universe." Over the seven years Bulma had finally managed to reach Super Saiyan God form due to after giving birth Nero training her endlessly for the years. When Drake became old enough to walk Nero started training him too.
Drake is now eight and he could transform from Super Saiyan 1-3. Nero left the others to train by themselves. This year another World Tournament was happening and Drake and Bulma are entering to fight. Bulma with the adults and Drake with the Juniors. After the fights Vegeta kills Pui Pui and Goku kills Yakon.
Gohan battles Dabura and kills him. Nero watches as Vegeta joins Babidi and fights Goku. Nero flys off and hunts Babidi. Babidi awakens Buu who then sees Nero standing in front of them. "You must be Majin Buu not what I expected to be honest."
Buu gets mad and steam blows out his head. "Buu doesn't like you! Buu kill you!" Buu flys at Nero and tries to punch him in the face. Nero moves under Buu's fist and grabs it.
He then judo flips him over and slams him on the ground. Nero jumps back a little and his claws grow with black flames infused with Hakai energy. "Amaterasu Claws of the Hakaishin King" Nero uses the Speedforce to slash Babidi 1000 times in a second. Babidi burns leaving nothing not even ash. Buu looks surprised and shouts, "Turn into chocolate!"
The beam hits Nero who then turns into a chocolate ginger bread man. Buu then picks him up and eats him. Nero lets Buu believe he won until a few days later Buu meets Mr. Satan and they become friends. Buu then splits himself making Evil Buu appear. While they both fight Nero breaks out and wanders around inside of Buu.
Evil Buu absorbs Good Buu. Nero releases his godly Ki and breaks out of Buu surprising Buu and everyone at the lookout. "I give your hospitality a 1 star rating due to how disgusting it was in there." Buu gets mad and charges at Nero. Nero turns around and dashes towards Buu cutting him in half.
Buu falls down and his lower half burns up in black flames. His upper half looks at Nero in disbelief. Nero smiled and started powering up. "Let me show you my true power." Nero transformed into his Ultimate form and lets everyone see him.
He looks at Buu and puts him in a "Tsukuyomi". While Buu was being tortured Nero cut off his arms and restrained him with wood style. When Buu snapped out of the Genjutsu Nero put his hand on his head. "Six Paths: Human Path" Nero removed Buu's soul and destroyed it with "Hakai". Buu's body stood still and the wood around his body wrapped around it and ignited in black flames leaving nothing behind. "I guess I should wish for everyone who was killed by Buu to be brought back."
