The huge snake-like body could only belong to a snake, but there was something different about this one. Its Green crystalline surface reflected light, giving off a shimmering glow that made Chris feel a rush of excitement.

Appearing before Chris was an Onix—no ordinary Onix, but a Shiny one!

A Green Body Onix, unlike the usual Rock-type, this rare sight was something you'd never expect to encounter outside of a handheld game.

Without hesitation, Chris commanded, "Makuhita, use Fake Out!"

"Maku~~" Makuhita, the little round-bellied Pokémon, immediately charged toward the Shiny Onix. But before the attack could land, the Onix, upon noticing humans, lost interest. It recoiled, giving Chris no opportunity for battle.

With a loud rumble, the Onix dove headfirst into the ground. Its massive form quickly vanished, leaving behind a long tunnel, while the dirt it kicked up pushed Makuhita back.

"Chase it!" Chris was ready to follow, but with a sudden crash, the tunnel collapsed.

Just like that... it got away.

Chris stood at a crossroads. Should he chase it or not? Even if the tunnel hadn't collapsed, could he risk running inside? Who knew when it might cave in again?

But this was a Shiny Onix!

Onix could evolve into Steelix, and Steelix could even Mega Evolve. A Pokémon like that had immense potential.

After some thought, Chris decided to give it a try. He pulled out the handheld console he always carried with him.

He commanded his in-game character to capture two Onix from Granite Cave, then sent them out into the real world.

"Go find an Onix that's different from you!" Chris directed his two Onix.

Based on the Pokédex, Onix could move through dirt at speeds of up to 80 km/h, the same as the speed limit on an open road. Only another Onix could hope to catch up with it.

The two Onix dug into the earth, creating two new tunnels. But after just two minutes, one tunnel collapsed, and after five minutes, the other gave way when a Diglett passed by.

"Good thing I didn't rush in," Chris thought with relief. If the tunnel had collapsed with him inside, his Kirlia might not have been able to teleport him out in time. The passage was too narrow.

More than ten minutes passed, and still no good news. Instead, the handheld screen showed the HP bars of both Onix dropping to zero in an instant. A message popped up:

[Your Pokémon Onix was defeated by Onix]

[Your Pokémon Onix was defeated by Onix]

"It defeated two level 13 Onix instantly? This Shiny Onix must be at least level 30," Chris speculated. Considering Onix had high defense but low physical attack, for it to take out two of its own kind so quickly, this Shiny Onix had to be powerful. At least level 40, he figured.

"Even if I had the chance to battle it, it wouldn't be easy," Chris thought, comparing his team's strength to the formidable Onix. Even with type advantages, at level 20 or so, the gap was far too wide for type matchups alone to overcome.

But no matter how strong Chris's desire was to battle, this Shiny Onix wasn't giving him the chance.

If it's going to stay underground in the rocks, there's no way I can fight it myself. At least, not for now.

To get it out, I'll need a more advanced Pokémon that can move faster through the dirt. Could I raise a Speed V Onix myself? Train a level 40 Onix... Chris glanced at his four Pokémon, all of them only around level 21.

It would take at least two months to train a level 15 Onix up to level 35. Is it worth spending two months just to get a Shiny Onix?

For most trainers, it would be worth it. But for Chris... shouldn't he be able to find at least one or two Shiny Pokémon in Granite Cave in that time?

"It's better to train a Rock-type or Ground-type Pokémon as the main force," Chris mused. A well-rounded team is essential for a good Trainer, and having Rock and Ground types would add important coverage to his lineup.

But... which Rock or Ground Pokémon should he focus on training?

In the game, the common Rock and Ground types are Aron, Geodude, Onix, and Nosepass. None of them seemed like the right choice. Even Aron, because Aggron is too slow. As for the others... they didn't quite fit either.

In reality, maybe it doesn't even matter that much.

Or... what if he could find a Pokémon with Earthquake and use that to shake the Shiny Onix out?

Chris quickly dismissed that idea. Using Earthquake in a mine would be a disaster—cave-ins, mudslides around Stoneclaw Mountain, and potential damage to the nearby villages. Plus, it wouldn't just shake out the Shiny Onix, but probably every Pokémon living in the area.

Two hours later, the fainted Onix had recovered and regained their stamina. Chris returned them to the game.

"Let you guys stay there on PC for a while," Chris muttered with some frustration, leaving the cave.

The next day, Chris came back again.

He spent an entire day in the mine, figuring that if he could encounter the Shiny Onix once on the first day, maybe he could do it again.

But for three days straight, there was no sign of the Shiny Onix. It seemed that their first meeting had been pure coincidence.

During this time, however, Chris had done his research. He confirmed that Onix is a territorial, solitary Pokémon. So, it was safe to assume that this small region of Stoneclaw Mountain was the Shiny Onix's territory.

That knowledge gave Chris some relief.

He tried releasing another Onix to track it down.

The result was the same. After ten minutes, his Onix was defeated again by the Shiny Onix.

Even so...

"Stoneclaw Mountain isn't a dangerous area," Chris reassured himself. "And the Shiny Onix is living underground, away from any attention. I can take my time and find a way to catch it when I'm ready."
