He knows Pokémon better than me.

After the application form was filled out, the station staff entered the data while briefly explaining the rules:
"The two are participating in a doubles battle, and each person can only use one Pokémon. At each subway station, a pair of trainers will get on."

"You must defeat your opponents before the train arrives at the next station and allow the next pair of contestants to board, otherwise it means your challenge has failed."

"When you reach the seventh platform, you will be greeted by two battle managers for the final challenge."

Xiao Zhi scratched his head; these rules were a bit convoluted, and he still didn't quite understand them.

"Let's go, let's go. I'll tell you the specific rules on the way."

As a local from Unova, Douzi knew the way well and pulled Xiaozhi directly towards the last carriage.

After all, the subway needs to operate, and the first 80% of the carriages are for normal subway service.

The last three carriages are the "official arena" for battling the subway.

Sizzle—!
Soon after, the subway arrived at the station, and people got on and off the train one after another, but the doors of the last three carriages did not open.

Upon seeing two people standing in the last carriage, passengers who were about to leave the platform stopped and began whispering among themselves.

"Huh? Anyone want to challenge the subway battle mode?"

"Interesting. That girl must be the president of BW Company, right? So young and accomplished!"

"Wait a minute, that boy next to me, why does he look so familiar?"

They immediately looked at each other with eager eyes and decided to stay on the platform and wait.

Xiao Zhi pointed to the speeding subway and asked curiously:
"How is this going?"

Douzi smiled and rolled her eyes at him, saying matter-of-factly:
"Subway Trainers naturally need time to prepare, right?"

A total of seven trainers will be challenged in one round. The platform will only open normally when the first pair of "Subway Trainers" are ready at the next platform.

"The subway will not stop along the way. Each station represents a different city, and there is a 15-minute drive between them."

Douzi raised a finger and said:

"In other words, we have to defeat the Metro Trainer within 15 minutes, or we'll have to get off the train and take the subway back in the opposite direction."

"Moreover, this process needs to be repeated six times before you can meet the final battle manager!"

"The Pokémon cannot be changed midway through the battle, and the time for treatment and rest depends entirely on the challenger's performance."

If you defeat your opponent in the first 5 minutes of a 15-minute drive, you can use the next 10 minutes to rest or take medication.

"I understand!"

Ash's eyes lit up; this rule was quite interesting.

He immediately rubbed his hands together, looking at the train door, waiting for the next train to arrive—

That said, the Allied players are quite enthusiastic about Metro Battle!

After all, trainers need to be gathered in a short period of time to wait for the challenge at stations in various cities.

"Of course! Battle Metro is incredibly popular in the Unova region!"

Douzi smiled. A few years ago, when the subway closed down, many people were still sighing and lamenting.

Moreover, as the challengers pass through more stations and the publicity spreads, the number of spectators in later cities will gradually increase.

In the end, it will turn into a spectacular scene with countless spectators crowding the crowd!

Regarding security issues
No major issues. Since the battle takes place in a train carriage, the entire train is made of a special alloy with extremely high hardness—not just natural metallic elements, but also incorporating fragments such as the scales shed by Aggron, the steel feathers dropped by Skarmory, and pieces of Nut's body.
It can withstand intense battles and direct attacks from Pokémon moves!
"Even this time, when the Metro Battle mode was relaunched, they introduced your new technology!"

Douzi said with a smile, and Xiaozhi blinked and quickly realized what she meant.

Aegislash's King's Shield Barrier!
"Then there's basically nothing to worry about."

Ash nodded. With the double shield of physical hardness and "magic defense," as long as the scale doesn't escalate to the level of a Z-Move or a Dynamax Move, it should be able to withstand it steadily.

Of course, mythical beasts are an exception.

Once the rules are clear, all that's left is to wait for the train doors to open.

When the next train arrived, the doors to the last three carriages finally opened normally. Ash and Touko exchanged a glance and went inside together.

"Piccoo~!"

Victini also hovered above Ash's head, its big blue eyes shining brightly; it was the one who truly enjoyed Pokémon battles.

Da da da!
Seeing the person in question board the train, many passengers followed suit, crowding into the fourth carriage to look back.

Once inside, and as the subway started moving, Ash realized that the Battle Subway should actually be called a train, not a subway.

It's not completely enclosed; the aisles connecting each carriage are open-air.

And if the fighting range is the last three carriages.
"That's right, the open passageways, including the carriages themselves, are all battlegrounds."

"The roads we travel on are not just underground tunnels; most of the area is actually the wilderness above ground."

Douzi grinned, fighting while speeding along – that's how wild he was.

Of course, if a Pokémon gets knocked over, that's the trainer's responsibility.

On the walls of the carriages, there are also real-time route maps—

Starting from Flying Cloud City, head north to Raven City, then head east, making a big detour before turning west again.

Finally, we arrived at our destination, Goldwheel Town, a central town located in the northwest corner of the Unova region.

Of course, the subway line is a large loop, going south from Goldwheel Town to Blowaway City, and then heading east back to Raven City.

Of course, none of that matters; the most important thing is your opponent in the first round.

The two arrived at the front of the last carriage. The challenger would board from the third-to-last carriage, while the middle carriage would be the competition area.

When the train finally stopped at Raven City station, two people boarded the train from the next carriage—and they were acquaintances!

A man and a woman, both wearing dark blue police uniforms, were Officer Jenny, who had come to arrest Quixote earlier. Beside them was a male police officer who looked quite honest.

"That's true."

Ash suddenly realized that the Officer Jenny he caught on Route 4 had been heading north.

They're really busy. They just finished catching someone and rushed over to become "Subway Trainers".

And the Pokémon of these two people are probably not surprising.

Click—!
As the train doors closed, signaling the start of the battle, the two officers simultaneously threw out Poké Balls.

boom!boom!
As the red light fell, Officer Jenny used a long-haired dog, which was enormous.

The male officer used the second-stage Hayok, which was more agile and even jumped directly onto the carriage, his gaze sharp! (End of Chapter)
