The moment John Doe appeared, Goku, Vegeta, and Gohan also materialized at the location where Evil Buu had emerged.
Evil Buu had already engaged in combat with Fat Buu, but as soon as they clashed, John Doe's group realized that Fat Buu was no match for Evil Buu.
It was evident that during the recent separation, the majority of the power had been absorbed by Evil Buu.
Within a few rounds, Evil Buu gained the upper hand and began to overpower Fat Buu.
John Doe spoke up, "Who among us should go to help? It's clear that Fat Buu is no match for Evil Buu."
Gohan quickly raised his hand and said, "I'll go! I'll go! After the Elder Kai unlocked my potential, I haven't had a chance to demonstrate my strength yet."
Hearing Gohan's words, everyone agreed, and while Evil Buu relentlessly attacked Fat Buu, Gohan swiftly moved forward with a flying kick, directly kicking Evil Buu away from Fat Buu's body.
"Buu, are you okay?" Gohan supported Fat Buu and asked with concern.
Fat Buu replied, "Gohan, I'm sorry. I couldn't stop it."
Gohan said, "It's fine. Leave it to us. We'll help you eliminate it."
After saying this, Gohan unleashed a powerful energy blast, and although he didn't transform into a Super Saiyan, the strength he displayed was no weaker than that of a Super Saiyan 3.
Gohan slowly approached Evil Buu and said, "The rest of the fight will be between you and me."
Evil Buu let out a cold laugh and threw a punch at Gohan.
Gohan dodged the attack with a quick tilt of his head.
"Damn it," Evil Buu muttered as he increased the frequency of his attacks. However, no matter how he struck, he couldn't even touch Gohan.
In the moment Evil Buu paused his attacks, Gohan seized the opportunity to deliver a low elbow strike, hitting Evil Buu directly in the abdomen.
Evil Buu was forced to bend over under the heavy blow and retreated a few steps in pain.
Gohan, seizing the advantage, spun around and delivered a flying kick that struck Evil Buu's head, sending him flying into a mountain peak, causing it to collapse.
Evil Buu burst out of the rubble, and his hands began firing countless energy blasts at Gohan.
Gohan performed countless evasive maneuvers, creating the illusion of multiple Gohans, continuously deflecting the energy blasts.
Then, Gohan retaliated with a massive Kamehameha wave directed at Evil Buu.
Evil Buu couldn't dodge in time, and the entire lower half of his body was swept away by the Kamehameha.
Gohan smiled and said, "You can't beat me. You should surrender."
Upon hearing Gohan's words, John Doe frowned and said, "Gohan, hurry up and eliminate it. This Evil Buu is a combination of the most evil parts within Buu. It's impossible for it to become as kind as the previous Buu."
Goku, standing nearby, added, "Yes, Gohan. Quickly get rid of it. Don't let any other situations arise."
After hearing his father and uncle's words, Gohan nodded. Then, he addressed Evil Buu, "You heard that. I'm going to eliminate you now. Prepare yourself."
After saying this, Gohan began to gather energy, preparing to use his full power to destroy Evil Buu.
However, at that moment, Evil Buu let out a cold laugh. As everyone was still wondering why Evil Buu was laughing, a soft, gelatinous substance resembling Evil Buu's body tissue appeared behind John Doe and rushed towards John Doe, Goku, Vegeta, and Fat Buu.
Although John Doe hadn't anticipated this situation, he had been vigilant about Buu's actions. He immediately transformed into Super Saiyan Blue and released a powerful energy blast.
The powerful energy wave spread in all directions, dispersing Buu's body tissue.
The others weren't as fortunate. They were directly enveloped by Buu's tissue and were pulled back into Evil Buu's body.
Fortunately, Goku and Vegeta hadn't transformed at that moment, so the power they could provide to Evil Buu was very limited.
After absorbing Goku, Vegeta, and Fat Buu, Evil Buu's body began to shimmer, and his aura became incredibly powerful.
He laughed loudly, "You're all a bunch of fools. Do you really think you can defeat me with your strength?"
"Now, your friends have become one with me. Do you dare to eliminate me? Let me tell you, they are alive inside my body. If you kill me, you'll be killing your friends as well."
Hearing Evil Buu's words, John Doe smiled coldly and said, "Sorry to disappoint you, but we have the Dragon Balls that can grant any wish. Even if we eliminate you, we can use the Dragon Balls to revive all of them."
Upon hearing John Doe's words, Buu's smile faltered.
However, while John Doe and Buu were arguing, John Doe was communicating with Gohan through telepathy, "Gohan, did you hear that? If you did, nod your head."
Gohan didn't know this technique, but he could tell that the voice belonged to his Uncle John.
So, he immediately nodded slightly.
John Doe continued, "Buu's current strength is no match for mine. So, if he wants to defeat me, he will definitely use the same method to absorb you into his body."
"When he tries to absorb you, immediately use an energy shield. The energy shield will prevent him from absorbing you."
"Once you're inside his body, quickly find Goku, Vegeta, and Fat Buu."
"Then, bring them out with you. I'll buy you some time."
"After you bring them out, I'll immediately eliminate this Buu."
After hearing John Doe's instructions, Gohan quickly nodded.
After the instructions were given, John Doe began to fight the new Buu. In his Super Saiyan Blue form, John Doe's strength was far beyond what Buu could withstand.
Unless Buu absorbed Super Saiyan 3 Goku, Super Saiyan 2 Vegeta, and added Gohan to the mix, they might be able to withstand John Doe's Super Saiyan Blue form for a short while.
But at that moment, Buu was no match for John Doe's onslaught. Under John Doe's relentless attacks, Buu's body couldn't hold up and was torn apart, with its tissue scattering and falling to the ground.
John Doe immediately communicated with Gohan through telepathy, "Gohan, be ready. Buu is about to use the Fusion technique again."
Just as John Doe had predicted, a piece of Buu's tissue slowly swam towards Gohan, enveloping him and completing the absorption.
After absorbing Gohan, Buu burst into laughter, "Hmph! Although I can't defeat you now, I can keep absorbing powerful warriors. I refuse to believe that I'll never be your match."
