Gastly's Hidden Poison-type Attribute

Swalot, a pure Poison-type Pokémon, can swallow anything and secrete highly toxic fluid from its pores.

Seeing the Swalot Fantina brought to him was a pleasant surprise for Cain. He initially only wanted to activate Gastly's poison core, but with Swalot, Gastly's Poison-type attribute could be maximized.

Cain had raised such a Gastly in his previous life before becoming a Gym Leader. However, Gastly was primarily a Ghost-type Pokémon, and even after fully developing its Poison-type attribute, it still couldn't compare to the likes of Drapion, which was primarily a Poison-type Pokémon.

But, it was enough for now.

Cain nodded and said, "Both of you, use Poison Gas on Gastly."

Swalot had a gentle and somewhat silly temperament, but its toxicity was top-notch among Poison-type Pokémon.

A dark gray mist enveloped Gastly, whose body was mostly made up of gas. The purpose of using Poison Gas was to change Gastly's appearance.

"Gastly, absorb this Poison Gas, Swalot, keep using Poison Gas."

The toxicity of the two Swalot was intense, and Gastly could hardly withstand even a small amount of Poison Gas. However, the transformation required enduring the pain, so Gastly forcibly absorbed the gas. The toxic gas mixed and circulated within Gastly's body, as it endured the onslaught of the gas.

This process continued until noon when Cain gave half of the 1,000 pokedollars he brought to Leo to prepare food for Swalot. This profitable task had Leo running faster than anyone.

Swalot, a Pokémon with a huge appetite, consumed two large piles of Pokémon food, which was only enough for a day's meal. This was the reason why Cain didn't catch Swalot in his previous life; he couldn't afford to raise it.

The Poison Gas cleansing process continued until the afternoon when some of the gas in Gastly's body began to turn dark gray like Poison Gas.

"Good, there's progress. Hang in there, Gastly, Swalot, don't stop using Poison Gas."

It was the most crucial moment.

The spraying, absorption, and refinement of Poison Gas continued until evening when Gastly's body was completely replaced by the dark gray gas.

The first step was a success.

Cain let Swalot eat all the remaining food, which might be their last meal.

Gastly also went inside the Bell Tower to absorb some life energy.

After Swalot and Gastly had mostly recovered their strength, the second step began.

"Swalot, use Toxic on Gastly."

Gastly's face turned upwards as the purple Toxic liquid sprayed on its face, penetrating through its eyes, pupils, and mouth into its gaseous body. The poison would pass directly through Gastly's gaseous body, leaving the toxins inside to stimulate the poison core.

It continued until dawn, but Cain had no sleepiness, staring intently at Gastly's changes.

Swalot spat out less and less toxic sludge, until it couldn't spit any out at all.

Now Gastly's poison core was activated, but to bring it to its full potential, it needed one more step. Swalot, you're out of luck.

"Swalot, swallow Gastly," Cain said with a cold look.

Swalot, not understanding the reason, foolishly swallowed Gastly.

At this point, Cain released Ditto, which transformed into Swalot. He moved away from it, anticipating a possible retaliation from Swalot.

"Gastly, destroy Swalot's poison sac and absorb its life toxin."

Gastly heard the command and began to act inside Swalot's stomach. Swalot realized the danger to its life and lunged towards Cain. However, its poison sac had already been destroyed by Gastly, and Ditto stood in its way, its small red eyes staring intently at Cain.

Cain knew that Swalot's poison sac was broken and had lost its toxicity, posing no threat. He said, "Open your mouth and let Gastly out."

At this point, Swalot wanted nothing more than to devour the devilish Cain. It ignored his command, knocked Ditto aside, and lunged at Cain, using Body Slam.

Cain sneered, "Seeking death, Gastly, Shadow Ball."

Gastly's Shadow Ball burst through Swalot's stomach, and it crawled out. Swalot slammed into the ground with a "thud" and died. Gastly's face had turned completely toxic purple.

The other Swalot, seeing its companion killed, was frantically trying to escape.

Cain let out a chilling laugh, "You can't escape. I can spare your life."

"Gastly, chase it down and use Hypnosis."

Swalot couldn't possibly match Gastly's speed. Gastly quickly struck, appearing in front of Swalot in an instant, and wave after wave of hypnotic light eroded Swalot's consciousness.

It quickly fell asleep...

"Ditto, pry open its mouth."

Gastly went into this Swalot's stomach, destroyed the poison sac, absorbed Swalot's life toxin, and then crawled out of its mouth.

"I told you, I won't let you die."

Cain withdrew the still-living Swalot into a Pokéball. After all, one Swalot had already died, and if both died, he couldn't explain it to Fantina. He had to restrain himself here. However, this Swalot had also lost its ability to use poison and had no value. But that was no longer his concern.

Cain looked at Gastly's color and nodded. Its face was a toxic purple, with dark gray poisonous gas, and the poison core was fully activated by the life toxins of the two Swalot. It was nearly perfect.

It was almost dawn, and the whole process had lasted a day and a night.

Cain called back his Gastly and Ditto, returned to the dormitory to take a shower, and then went to the training ground after a short nap.

At this time, Morty and the other two were already training. Cain walked over and handed a Poké Ball to Fantina, saying, "Here's your Swalot back."

"How come there's only one? I clearly lent you two," Fantina questioned.

"The other one refused to train last night, so I punished it. It actually attacked me and was killed by Gastly," Cain said nonchalantly.

"You're lying!"

"The body is behind the Bell Tower, you can go see it if you don't believe me," Cain said confidently.

"You owe me one anyway." Actually, Fantina had never seen the two Swalot before; she had just bought them from the black market. She wanted Cain to compensate her just to suppress his arrogance.

"Heh, compensate? I haven't even accused you of trying to harm me on purpose yet."

Cain's angry roar frightened Fantina, causing her to retreat a few steps with tears in her eyes, biting her lip.

At this moment, Morty quickly stepped in to comfort her, "Don't be sad, I'll give you one later. It wasn't Cain's intention, otherwise, he would have killed both of them. You can't expect Pokémon bought from the black market to be completely obedient."

"I don't want this one either." After saying that, Fantina threw the Poké Ball containing the other Swalot out of the Ecruteak Gym.

Although Swalot had lost its ability to use poison, it still had some decent Normal-type moves. Whoever picked it up would be lucky.

"There's nothing more for me to do here, so I'm going to use some TMs." After saying this, Cain waved and left.

After Cain left, Fantina couldn't help but burst into tears.

Yan thought it was just a children's quarrel and didn't want to interfere.

Raikou frowned, realizing that things couldn't be that simple.
