Stage One: Zubat

It feels important to note that Zubats are blind creatures. They don't develop eyes until they evolve into Golbat, so tiny Zuzu had absolutely no way of knowing it was different from the other kids, as ultrasound does not show color. Since his friends could not tell what his color either, his parents thought it unnecessary to tell them, or Zuzu himself, about his condition, as they didn't want to burden him with the perpetual fear of humans. They had strict rules, but they allowed Zuzu to have a few years of peace, before the inevitable realization that he was a walking target.

Zuzu had to be with his parents at all times, wasn't allowed to hunt alone, and even when they left the cave at night to visit the nearby forest, he was not allowed to go anywhere near civilization. Zuzu would often face in that direction, so far out of his sonar's range, and yet, making sounds he could hear even at a distance.

"Zuzu, it's getting late, let's bite a Tauros and go back home!" screeched Zania, interrupting Zuzu's thoughts.

"Sure thing, Mom…" clicks Zuzu. But his head is elsewhere, and his forest-green wings were getting tired, so he didn't take off just yet. In the meantime, Zania argues with Golbez.

"He's getting curious… I worry about what will happen if a trainer comes into the cave. I worry that he might follow the example set by his peers and blindly attack, and he will be caught. We should move somewhere where Trainers won't come as often, like the Cerulean Cave."

"We would not survive in the Cerulean Cave." Replied Golbez. "The second a Rhydon decides to use Smack Down or Rock Blast we are done for. Plus, there are Gravelers in there, and they'd eat us for breakfast. I even heard that something sinister had moved in there, something cruel, that even the humans dare not face."

"I know it would be dangerous but I see no other way out. I've heard of Zubats surviving there before." Argued Zania.

"They are the strongest Zubats, the ones that refuse to evolve so that they can get stronger faster. Much stronger than you or I, and certainly not a place for Zuzu."

"Wait… Where is Zuzu?" Screeched Zania.

Unbeknownst to them, their son had rebelliously stayed still for a few more minutes, and they had flown outside of his effective hearing radius. When Zuzu decided to join them, he made his best guess as to which direction they had flown into… and went a completely different way.

"Zuzu!" the parents cried out, but their ultrasonic cries were not enough to reach their child.

After about an hour of searching, they heard a sound that paralyzed their very souls.

"Oh cool! A shiny Zubat!"

That was human speech. Their worst fears were coming true!

They flew as fast as they could to the source of the sound. Zuzu was flying around the trainer aggressively, looking extremely confused. The trainer himself looked young, about ten or eleven in human years, so it looked like he was at the start of his adventures. Without even letting a Pokemon out, he threw a Pokeball.

"Pokeball, go!"

Shake.

Shake.

Shake.

Zuzu escaped!

"Shoot! It was so close, too!" Yelled out the trainer. "It looks like I'm gonna have to weaken you first then! Go, Onix!"

The forest was suddenly filled with a towering snake of rock. It was obvious that the Onix was still very young, just a little bit older than Zuzu, but even a weak Onix is a force to be reckoned with.

Rushing as fast as he could, Golbez used Supersonic, attempting to confuse the Onix. It didn't work.

'Onix, use Rock Tomb!

Zania saw it all. Multiple towers of rock sprouting from the ground and trapping her son, before collapsing upon themselves, wounding the child fatally. This trainer had not yet learned to measure his Pokemon's strength. It was likely that he'd just caught the Onix and had not actually seen how powerful the serpent was.

Zania saw all this in her mind's eye, and decided she could not let it happen. She flew as fast as she could and tackled her son out of the air. Immediately, the stone pillars formed around her. It was to late to avoid the attack. She was going to take the full force of it.

As the rocky prison was completely formed, and Zania saw no hope of escape, she managed to let out one last Ultrasonic cry as she heard the structure start to collapse.

"Golbez! Take Zuzu as far away as you can! I love you both from the bottom of my heart!"

Golbez did not waste a single second. He used his feet to grab Zuzu's wings and flew away as hard as he could.

"Dad! Dad, what's going on?" Asked Zuzu.

"We… we have to go!" Golbez could not contain his tears even for a second. "It's what your mother would have wanted!"

"Dad! We have to go help her!"

"Don't you think I want to?"

"Then let's go!"

"No! If I let you go you'll die!"

"Let go of me!"

At this point, Zuzu's wing started glowing in power as he used Air Cutter. His father, not expecting the blow, had the air knocked out of him.

"Wait, son, don't go!"

"I'm going, even if I have to go through you! Please Dad, step aside!"

"I can't dammit!"

Without warning, Zuzu's wings started glowing again as he used Air cutter again. And again. His father was trying to stop him but could not bring himself to attack his own son. Eventually, Golbez fell to the ground, too hurt to keep flying.

The second that Golbez hit the ground, Zuzu was enveloped in a bright, white light.

"What… what is happening?" Asked Zuzu.
