Roy hadn't only obtained that beginner-level magic before—he had also acquired a magical item.
The Babidi Energy Collection Jar!
In the original Dragon Ball, Babidi used it to gather enough energy to revive Majin Buu. He controlled Spopovich and his partner, sending them into the World Martial Arts Tournament to harvest energy.
Although the jar looked strange, its effect was incredibly powerful.
It could even completely absorb the energy of Son Goku in his Super Saiyan Second Form!
Roy hadn't used it before because he was worried about incompatibility between the absorbed energy and his own.
There were plenty of examples of that kind of power causing backlash. As for Majin Buu… with that kind of body, would he even need to worry about incompatibility?
So Roy had sealed this item away.
Now he had taken it out again because Dark Roy and Roy were essentially the same.
There was no need to worry about energy incompatibility at all.
Roy had also discovered that this energy collection jar had two functions.
One was simply to collect energy from others. The drained person could recover through healing, and the jar could be reused indefinitely.
The other was a one-time function—completely extracting the opponent's energy source, making it impossible for them to ever recover their original strength, no matter how much they were healed. Extremely vicious.
Because of how cruel it was, this method could only be used once. After extracting the source energy and injecting it into another person, the jar would be completely destroyed.
After Roy took out the energy collection jar, the already-controlled Dark Roy slowly stood up and said respectfully:
"Roy-sama."
"Mm." Roy nodded.
This kind of mind-controlling magic was somewhat similar to characters manifested through Nen abilities.
They retained independent personalities, but deep within their minds was an engraved belief:
"He is my master. I must be loyal to him. I will protect him even at the cost of my life!"
However…
Roy stroked his chin, still not entirely reassured.
"Bark like a dog."
Roy stared directly into Dark Roy's eyes, trying to detect anything unusual—but all he saw was fanaticism.
Yes—fanaticism. Excessively fanatical eyes.
"Woof!"
The bark echoed clearly throughout the room.
Roy's lips twitched. Seeing someone with the exact same face as himself barking like a dog felt absurd no matter how he looked at it.
"Insert this into your body."
Roy handed over the jar.
"Yes, Roy-sama!"
Dark Roy immediately inserted the jar into his own body.
The numbers on the jar skyrocketed, and its surface began to glow with white light.
Meanwhile, Dark Roy's complexion visibly deteriorated, just like Son Gohan in the original story.
"Here… Roy-sama…"
Before he could finish, Dark Roy lost his balance and collapsed to the ground.
"Looks like there's no problem."
Roy held the now energy-filled jar and confirmed.
After all, this guy had completely drained his own energy without leaving even a trace.
If this had been before he was controlled, with his original personality, there was no way he would have allowed himself to fall into such a helpless state.
And even if he had any hidden intentions, he wouldn't be able to cause any trouble now.
Because this evil mind-control spell also had an additional effect—it allowed the user to physically torture and destroy the target.
In the original Dragon Ball, Babidi used this very magic to kill Spopovich.
After increasing someone's power, it also became easier to torture and destroy them with magic.
However, if the controlled person was far stronger than the caster, their power wouldn't increase. While torture and destruction were still possible, it only worked if the target was weaker than the caster.
This was why when Vegeta had the "M" mark on his forehead, his strength didn't increase like Spopovich's, and he didn't take Babidi seriously at all.
Since Roy was stronger than Dark Roy, he had naturally given Dark Roy a slight boost in power, making it easier to control him.
Then, in the next moment, Roy inserted the jar into his own body, injecting Dark Roy's energy into himself!
Crackle—
The numbers on the jar quickly dropped to zero, and Roy felt a surge of powerful energy flow into him.
However…
Roy raised an eyebrow.
"This power feels quite unstable."
After refining it carefully to avoid damaging his foundation, it only resulted in a very slight increase in his strength.
"Looks like my body isn't as monstrous as Majin Buu's—unable to absorb all the energy perfectly."
Abandoning the idea of treating Dark Roy like a renewable resource—harvesting his energy regularly—Roy began to think about how to eliminate him completely.
Roy already had a complete plan.
He would have Killua find Alluka and make a wish to remove the shared life link between Roy and Dark Roy—the condition where if one died, the other would also suffer fatal consequences.
Then he would use the energy collection jar to completely extract Dark Roy's source energy.
Finally, one Ki blast would erase him entirely—from consciousness to physical body—in a clean, humane manner.
However…
A glint flashed in Roy's eyes.
Since he could absorb source energy, then if Dark Roy learned Nen and developed his own ability…
And then Roy absorbed that source and injected it into himself—
Wouldn't that mean he could possess two Nen abilities?
Roy felt it was worth trying.
After all, there was no significant risk.
With that thought, Roy immediately decided to help Dark Roy awaken his Nen.
…
"Tsk tsk, I didn't expect it to be this kind of Nen ability. Quite surprising. But considering your original personality, it actually makes sense."
Roy clicked his tongue in amazement.
After awakening Nen, Dark Roy immediately developed his own ability—and it was a Specialization-Type.
Originally, Roy had planned to absorb Dark Roy's power right away, but now he changed his mind.
This Nen ability was excellent—easy to grow stronger, though it required a certain kind of "nourishment."
Roy decided to let him out to grow stronger first.
Since he was his puppet, the stronger the puppet became, the better.
