Chapter 475 Seiya's Advantages: Attribute Combinations and Tactics!
Upon hearing Karune's command, Seiya did not hesitate and immediately transformed into Vaporeon.

After all, in front of outsiders, he is now Karune's Pokémon, so he should give her some face.

Moreover, he had already roughly figured out Ash's Greninja's strength, and with his experience and reaction, he had a great deal of leeway if the command was wrong.

"Use Rain Prayer!"

As Karen, Ash, and even Clemont and the others watching the battle watched as Seiya transformed from Jolteon into Vaporeon and then used the "Rain Dance" move, they all wore expressions of confusion.

Logically, Jolteon should have a type advantage over Greninja.

Both Ash and Clemont were clearly puzzled at this moment as to why Karen wanted Seiya to become a Water-type Vaporeon.

Furthermore, while the move "Rain Dance" can create a terrain more favorable to Water-type Pokémon, don't forget that Greninja is also a Water-type Pokémon.

As thick dark clouds gathered in the sky, a torrential downpour began, so heavy and widespread that Hitchron and the others marveled at the power of this "rain-praying" technique.

To be honest, not only Ash and Clemont, but even Karen, who was commanding Seiya in battle for the first time, was clearly taken aback when she saw the strength of Seiya's "Rain Prayer".

There aren't many Pokémon that can use the "Rain Dance" move, and most Pokémon's "Rain Dance" can only moisten the ground at most.

However, when the Vaporeon form used "Rain Prayer," a small lake was created out of thin air on the field!
If it weren't for the fact that Karen and Ash are trainers, his "Rain Dance" move could actually be even stronger.

Because of the water feature on the field, Greninja, now in its Bond Form, has become even faster and more agile.

“Miss Karune, although I don’t know why you wanted your Vaporeon to use the move ‘Rain Dance,’ you seem to have forgotten that my Greninja is also a Water-type Pokémon.”

Seeing Ash's spirited expression, Karune also showed a confident look on her face.

"No, I naturally know that Greninja is a Water-type Pokémon."

However, Ash, you seem to have forgotten something very important: my Eevee isn't a single-type Pokémon.

"Seiya, the stage is ready. Now it's your turn to perform. Transform from Vaporeon back into Jolteon and use the Electric move on the water on the ground!"

Upon hearing Karen's command, Ash and Clemont's faces immediately lit up with a look of sudden realization.

When Seiya of Jolteon used the Discharge move, golden arcs of electricity spread out of the surrounding water at an astonishing speed!
"Greninja, jump into the air!"

"Koga—!"

Water conducts electricity, and with the entire area currently covered in water, escape is virtually impossible.

Jolteon's Electric attack might be less powerful due to the large area covered by the water, but even if it can't directly disable Greninja, it can still put it in a state of temporary paralysis.

Commanding Greninja to jump into the air was already a stroke of genius from Ash.

However, even Ash's sudden inspiration had already been anticipated by Karune.

"Now's the time! Use the 'Thunderbolt' special move!"

The Greninja, leaping into the air, temporarily avoided the effects of the water's conductivity, but in mid-air, it became an inescapable target. A golden bolt of lightning struck from the rain-praying clouds, and the Greninja, falling directly to the ground, let out a scream and plummeted to its death.

As a Water-type Pokémon, it was instantly rendered unable to battle after taking such a powerful Electric-type attack, coupled with the damage it had already accumulated.

"That's amazing! First, you used Vaporeon to set up the field, then used the physical reaction of water conducting electricity to lock Greninja's speed, and finally dealt it a powerful electric-type move?"
Karune truly lives up to her title as the league champion; she maximized the advantage of that Eevee's ability to change attributes and form.

Should this be considered an "attribute synergy tactic"?

Seeing Seiya take down Greninja almost without taking any damage, Clifton couldn't help but exclaim in admiration.

As the Gym Leader of Lumiose City, he had to admire Ms. Karen's brilliant tactics; Ash's defeat was entirely justified.

Because once Ash and Greninja enter that special bond connection state, it seems that any injuries Greninja suffers will be reflected back to Ash, the trainer, to some extent.

So in this battle, Greninja lost its ability to battle, and Ash also fainted on the spot.

When he woke up again, it was already evening.

"It seems that the power you and Greninja obtained also carries certain risks. Unless you encounter a strong enemy, it's best not to push yourself too hard."

Seeing Ash awaken from his coma, Serena and the others breathed a sigh of relief, while Karen, standing nearby, offered some words of advice.

“Miss Karune, I’m so sorry to have worried you. But I didn’t expect that I would lose again this time. Counting the time when I first came to the Kalos region, I have lost to Eevee twice now.”

When Ash woke up, he looked at Seiya sleeping on Karune's lap and a look of regret appeared on his face.

Although Ash never thought he could win this battle, he also didn't expect to lose so easily.

"Don't be discouraged. You and Greninja are already very strong, and I can sense that you still have a lot of room for improvement."

And I also want to thank you this time, because of you and Greninja, I learned how to maximize Seiya's strength.

"Holy?"

"Seizai is the name of this Eevee, not its species name, but its individual name."

Hearing Karen's explanation, Ash and the others weren't too surprised. After all, in the Pokémon world, there are indeed many trainers who give their favorite Pokémon a different name.

Furthermore, Ms. Karune's Eevee has multiple evolutionary forms, and calling out its species name during battle is indeed quite troublesome and confusing.

After seeing that Ash was unharmed, Karen encouraged Ash and his friends for a few words before getting up to leave.

As a league champion and popular actress, she is usually very busy. Today, she participated in the Triple Crown Satellite Tournament and had a Pokémon battle with Ash. Her manager must be going crazy with worry.

"Miss Karuni is really strong. No wonder she is the league champion of the Carlos region. It seems that I still have a long way to go to reach her level."
