Restoration

Just as Onix was about to unleash its Dragon Breath, Yuga's Gengar and Mismagius appeared in front of him and simultaneously used Shadow Ball, interrupting Onix's Dragon Breath attack.

"Zaden, you go and join Zinnian and the others first. Leave this to me," Yuga said, turning to Zaden, who was trembling with fear.

"But..."

Watching the colossal serpent before them, Zaden was worried that Yuga might not be able to handle it.

"Don't worry, I'll catch up soon."

Although this Giant Onix was formidable, it was still only at the pseudo-Elite level. Yuga didn't believe that Gengar and Mismagius, both Elite level Pokémon, would lose to it when working together.

Thinking about his status as a Elite level Trainer, Zaden reluctantly nodded and found his Skarmory. He then swiftly left the southern bank of the canyon riding on his Luxray.

The Shadow Balls unleashed by Gengar and Mismagius exploded in Onix's mouth, causing it to emit a mournful cry. Its massive head tilted to one side, toppling numerous trees in the process.

Onix twisted its enormous body and swung its sturdy tail, using Iron Tail against Gengar and Mismagius.

While Onix could sense the dominance of Gengar and Mismagius, which were Elite level Pokémon, it felt no fear. Its sole focus was to tear apart the small creatures before it.

Yuga knew that if he allowed this Giant Onix to rampage, the entire canyon would soon be leveled. Next year, when the hunting Butterfree wanted to migrate through here, it would be impossible.

Under Yuga's command, Gengar and Mismagius joined forces to use a spatial technique.

Onix's massive body was immediately trapped within a transparent energy space. It continuously raised its colossal tail and pounded the spatial barrier, causing it to tremble incessantly.

Since Gengar and Mismagius had broken through to the Elite level, the spatial technique they jointly executed was already quite stable. Ordinary Elite level Pokémon would find it challenging to disrupt it.

However, Onix's immense size meant that Gengar and Mismagius had to expand the spatial area to contain it. As the volume of the space increased, the power of the spatial technique became diluted, and its stability was compromised.

Inside the space, Onix rampaged, while Gengar and Mismagius evaded its attacks and simultaneously used Shadow Ball to strike at it.

Onix had strong physical defense but weaker special defense. Faced with the combined assault of two Elite level Pokémon, the colossal serpent grew increasingly irritated.

Gengar and Mismagius were both agile Pokémon, but Onix's size made its movements clumsy within the confines of the spatial field. Consequently, it found it almost impossible to attack Gengar and Mismagius.

If it were outside, Onix could move freely, and even the wind generated by its body movements would be powerful. Gengar and Mismagius would have a much harder time dealing with it.

Inside the spatial field, Onix's body was covered in injuries from the frequent attacks. Furthermore, it had been using brute force to continuously crash against the spatial barrier, which was draining its stamina rapidly.

As it watched the two small creatures darting around before its eyes, Onix felt increasingly frustrated.

So, after giving it some thought, it stopped attacking Gengar and Mismagius and, with red eyes, used Double-Edge. It disregarded the consequences and slammed into the spatial barrier.

Not content with just one strike, it used its tail and head alternately, continuously battering the spatial barrier. The spatial field began to shake violently.

Onix had the ability "Rock Head," so it wasn't afraid of the recoil damage from Double-Edge move. So It used this ultimate move like Double-Edge fearlessly.

The vibrations within the spatial barrier became more and more intense, and maintaining the stability of the space became increasingly challenging for Gengar and Mismagius.

Finally, with a resounding "boom," the transparent spatial barrier shattered abruptly, turning into sparkling energy fragments that dispersed into the air.

As the space collapsed, Onix delivered one final blow that cleaved a gaping hole through the air. Its enormous tail struck the river at the bottom of the valley, instantly cutting it in half.

Seeing the space rupture, Onix seemed to lose all its strength in an instant, crashing down to the ground.

Although it had successfully broken through Gengar and Mismagius's spatial barrier, it had exhausted all its energy due to the frequent use of Double-Edge.

The more powerful the move, the more energy it consumed.

Half of Onix's body lay across the river, blocking the water flow. The river redirected itself along the embankment, soaking Onix's body.

Gengar and Mismagius slowly descended from the sky, landing on Onix's head to examine its condition.

Onix had truly lost its ability to fight.

As Yuga looked at the chaotic scene in the canyon, he felt somewhat helpless. Although he had done his best to protect the canyon, Onix's destructive power was simply too great, and every move it made caused massive devastation.

Within the canyon, many trees and terrain had been destroyed by Onix, not to mention the river that had been abruptly cut off.

Seeing Onix fall, Yuga rode on his Charizard and found his Dragonite, Chatot, and Vivillon, who had been thrown aside by Onix. He provided them with some basic healing and recalled them into their Poké Balls.

Fortunately, they had only suffered a single blow from Onix, and their injuries were not severe. With some rest, they would recover without any major issues.

After tending to his Pokémon, Yuga rode on Charizard and landed beside Onix. He then threw a Heavy Ball, successfully capturing Onix.

Since Onix had completely lost its ability to battle, it offered no resistance when being captured in the Poké Ball.

The moment Yuga successfully captured Onix, he received a notification from the system that the mission was complete.

After capturing Onix, Yuga didn't rush to leave. Instead, he released Onix and used his special abilities to provide it with some healing.

Although still somewhat angry, Onix understood that it had been captured by the human before it and refrained from attacking Yuga again.

Therefore, Yuga made an agreement with Onix. He would help Onix evolve and provide it with the minerals and nutrients it needed, and in return, Onix would accompany him.

Onix wasn't a fool. If someone was willing to take care of it, it had no objections.

After reaching an agreement with Onix, Yuga had it restore the canyon's terrain, including the river that had been interrupted.

For a massive Rock and Ground-type Pokémon like Onix, this task was not difficult.

Yuga didn't want such a place, used by Beautifly and Dustox for courting and migration every year, to be destroyed.

As for the trees that had been knocked over, Yuga and Onix were powerless to do anything about them. If Florges were here, perhaps she could find a solution.

So, the issue of vegetation would have to rely on the self-healing abilities of the Petalburg Forest.
