After her creation Buu spent the bulk of his time with his little girl, she was incredibly smart for her age, due in no small part to Science Cat's tutoring; and she sweeter then the bubblegum she was made of. He also faced heroes who came to earn the right to be known as the greatest hero of Ooo, he dispatched each of them easily. When his daughter asked why they attacked him, he explained that they wanted to be known as the greatest hero of Ooo, he didn't need to tell her of his impending demise just yet. The only person who actually knew the true reason for the contest was Marceline, Buu didn't even tell Peppermint Butler. Eventually Billy arrived to challenge Buu. Billy was as close to human as Buu's creations got he had dark grey skin, six fingers on each hand, was over twelve feet tall, and incredibly strong, but other than that he was human. Billy fought Buu with everything he had his energy gauntlet actually equaled Buu's lesser energy attacks. After Billy ran Buu through with his sword Buu announced he was indeed the greatest hero in Ooo. Billy didn't understand why considering his sword had no affect on Buu. After a great feast in Billy's honor Buu took him aside and explained that in his age he was growing weaker and needed a bodyguard for him and his daughter, it was partially a lie but Billy believed him all the same.

Shortly before Princess Bubblegum's fourth birthday Buu felt he had enough energy to create another human. Instead of leaving her he took Bonnibelle, and Peppermint Butler, Billy, and Marceline with him for a picnic in the forest. When they got there he told Marceline to come with him and they snuck off to a different part of the forest. There he made another human this time making sure it'd be a boy he gave him strength, courage, kindness, righteous anger, loyalty, durability, quick healing, a near endless supply of energy, and again Goku's golden locks. He held the boy and smiled placing him down on a leaf.

"You sure you want to leave him just lying here naked?" Buu realized Marceline had a point; he began making the boy clothes but his antenna fizzled out as soon as he finished the boy's hat.

"Stupid things on the fritz again, I can't make anymore clothes."

"That's not what I meant."

"I know Marceline, stay here and watch and if necessary take care of him. Until someone nice comes along and takes him."

"Whatever you say Buu, I'll head back to the castle tonight hopefully."

"Good I have to get back to Bonnibelle." Marceline raised an eyebrow. "I meant the others."

"No you didn't." Buu smiled and walked back to the group and lied about how Marceline remembered she had something else to do. Later that day a nice dog couple came and picked up the boy and decided to take him home as the couple and their pups started to leave, one of the pups sniffed the bush Marceline was hiding in, fearing a golden shower Marceline made one of her best scary faces and freaked him out, scarring young Jake for life.
