"It worked!"
Seeing that the Eight Trigrams Sealing Style had taken effect, Mr. Hawking waved a hand and dispelled the Wood Dragon Technique.
Sealing Techniques were ninjutsu that used curse marks to lock down an opponent. Those who were sealed would bear sealing formulas on their bodies. They could seal not only energy, but also souls and physical bodies.
Mr. Hawking had traded for quite a few Sealing Techniques from Tsunade long ago, and he had also consulted many jonin skilled in sealing.
Now that he had the Rinnegan's enhancement, he could basically use all kinds of Sealing Techniques with ease.
Hulk's power came from exposure to Gamma Rays. It could be regarded as a physically powerful genetic mutation, while Hulk's consciousness was the manifestation of a second personality, a problem of the soul.
In theory, both should fall within the range of things that could be sealed.
Although the worlds were different, many things were fundamentally the same.
The Naruto World also had all kinds of genetic research, and Orochimaru had conducted no shortage of biological experiments. It simply did not rely on technological power as heavily as the Marvel Universe did, relying more on the power of ninjutsu.
The Eight Trigrams Sealing Style was a Sealing Technique created by the Fourth Generation through stacking Double Four Symbols Seals. It was best suited for sealing tailed beasts.
By using the Eight Trigrams Sealing Style on Hulk, Mr. Hawking intended to seal Hulk's power within Banner's body just as one would seal a tailed beast, creating a mode similar to that of a Jinchuriki.
"I've finally changed back."
Having returned to normal, Bruce Banner dropped onto the ground and panted heavily.
Whenever he transformed into Hulk, he was like a bystander. He could only watch Hulk wreak havoc from within
