"What do you mean by that?" Ethan asked, startled.
"I mean that when you want to evolve, you can do it anytime, anywhere!!"
As Gastly spoke, its body was suddenly engulfed in a bright light. When the light faded, a completely new Pokémon appeared before Ethan.
Ethan was utterly astonished. Without any warning, it had evolved into Haunter!? Compared to its previous form, Haunter's round body had changed shape. Not only had the purple mist around it disappeared, but it also now had three spike-like protrusions on each side. Additionally, it had a pair of disembodied claws floating in mid-air.
Ethan took out his Pokédex.
Pokédex: "Beep. Haunter, the Gas Pokémon. Ghost/Poison-type. Haunter is the evolved form of Gastly and typically lives in haunted houses and graveyards. Haunter is more powerful than Gastly and will hide in the shadows, waiting for its prey. If it licks you with its gaseous tongue, it can steal your very soul."
"Hey, it just evolved just like that? How did you do it?" Ethan asked, flabbergasted.
Thinking about it, though, Gastly's evolution was unexpected yet made perfect sense. After all, before meeting him, Gastly had lived for who knows how many years. By all logic, it should have been able to evolve into Haunter long ago. The only reason it hadn't was probably just because it didn't want to.
"What's so surprising about that?" Haunter's claws kept opening and closing as it got used to its new limbs. It said dismissively, "I could even evolve into my third form right now!"
"Whoa, hold on!" Ethan quickly stopped it. "Evolving too quickly isn't a good thing. You should get used to your new body first."
At this, Ethan turned his attention to Magikarp.
"But speaking of which, as happy as I am about your evolution, our original problem still isn't solved, is it? Hey, Haunter, quickly try to see if you can communicate with Magikarp!"
"Me, communicate with it!?"
Haunter's face was a mask of astonishment. It flew above Magikarp, staring at it wide-eyed for a while before coming back quietly.
"No good. This guy's brain seems to be completely empty. I have no idea what it's thinking!"
After saying this, it saw Ethan frowning thoughtfully and offered an analysis, "But since you said it's on the verge of evolving, stuck at a critical point, it must be lacking some experience or stimulus! I think a battle would quickly help it complete its evolution."
Experience? Stimulus?
Ethan's eyes suddenly lit up, as if he had a brilliant idea.
Sensing Ethan's intent, Haunter said, "No way? You're actually going to make it battle? But this guy only knows Splash. It doesn't do any damage! It would just be a punching bag for any other Pokémon!"
"That's no problem for me!" Ethan clearly had a plan. He looked at his other Pokémon and instructed, "Everyone, spread out and see if there are any wild Pokémon nearby!"
They were currently in a river inlet beside a road, with a small forest not far away. The Pokémon scattered to search. Kirlia quickly found a Bug-type Pokémon sleeping on a tree trunk in the forest—a Weedle.
It chirped softly, and when Ethan arrived, he looked at the Pokémon and nodded in satisfaction.
"A Weedle? Perfect. Everyone, keep an eye on it. Make sure it doesn't get away!"
Despite their confusion, the Pokémon obediently surrounded the Weedle, cutting off all its escape routes. With everything in place, Ethan turned to Charmander. "Use Ember!"
Charmander tiptoed closer, took a deep breath, and shot a spray of fire at the sleeping Weedle, instantly engulfing it.
Fire beats Bug. It's super effective!
"Hehe, Magikarp, now, let me help you!"
Seeing that the Weedle was mostly incapacitated, Ethan picked up Magikarp and walked in front of the Weedle, holding it high above his head.
"Go, Magikarp! Let it see our combination attack! Silly Fish Smash!!"
With a mighty toss downward from Ethan, the next second, Magikarp's bony, scaly body slammed heavily into the Weedle.
Thump! The two Pokémon collided with a dull thud.
Seeing that the Weedle still hadn't fainted, Ethan raised an eyebrow.
"Huh? It's still not down? How tough! Don't worry, Magikarp! Let's do it again!"
With that, he lifted Magikarp high again and slammed it down hard! This time, the Weedle couldn't take it anymore and completely fainted. Magikarp's body, just as Ethan had hoped, was suddenly enveloped in a white light!
Excellent! Mission accomplished!
With a dragon's roar that shot into the sky, a massive Gyarados appeared before Ethan. Its body was about six to seven meters long, with a blue back and a pale-yellow underside. In addition to a three-spiked horn, it had two long whiskers and a gaping maw. Its eyes seemed to be perpetually filled with rage.
Pokédex: "Beep. Gyarados, the Atrocious Pokémon. Water/Flying-type. It evolves from Magikarp. Its temperament is extremely violent, and its scales are as hard as steel. Its teeth can crush rocks. Once enraged, it can incinerate anything with its furious blasts, a truly ferocious Pokémon."
This evolution of Gyarados, though still looking a bit goofy, was a qualitative leap in power. But perhaps due to its innate nature, the first thing it did after evolving was not to get used to its new body but to launch an indiscriminate attack on its surroundings!
"Hey, what's wrong with this guy's head?!" Haunter flew into the sky, dodging Gyarados's wild rampage, and exclaimed to Ethan, "Did you break it by throwing it like that?"
"You idiot, what are you talking about!" Ethan also quickly backed away, leaving Gyarados's attack range. "Didn't you hear what the Pokédex just said? Its nature is just that savage!"
"So what do we do now?" Haunter asked. "Do we just wait for it to stop?"
"Of course not! We went to all this trouble to make it evolve; we can't just let it run wild now!" Ethan waved a hand forward and commanded, "Alright, everyone, don't just stand there! Let's teach this disobedient Pokémon a lesson! Daring to attack its own Trainer and companions? It's time to show it who's boss!"
