Battle Arcade

After leaving Veilstone City, the gang came to a big building that resembled a very large circus tent with circular domes on top with all sorts of colors painted on it such as red, blue, yellow, orange and white. This was the Battle Arcade where Ash could earn his next frontier plaque.
"I wonder what this challenge is about?" Ash asked, remembering the Battle Hall and Battle Castle.
"Well, let's go find out." Dawn smiled.
Inside the entrance was like a reception hall and there were four doors leading to another room. Matt was in the entrance hall waiting for the gang.
"Well, well, well, it looks like I arrived before you kids did." Matt said.
"What's the Frontier Brain like?" Ash asked him.
"She's a woman named Dahlia. Arcade Star Dahlia to be specific." Matt explained. 
"What's she like?" Ash asked.
"Well let's just say she's a fun-loving type." Matt said. 
He opened the door to the battle arena. It looked like a dance floor and on the wall was a big screen that looked like a game board. There were lots of people dancing to music.
"This looks fun." Tomo said.
"People always come here for all sorts of dancing and they host games here too." Matt said.
Just then a woman with long black hair came up to Matt. She was wearing a yellow and white jumper, blue trousers and yellow shoes.
"It's been a while since I've seen you Matt." She said.
"Same here Dahila." Matt said.
The woman is the Frontier Brain Arcade Star Dahila.
"Ash, this is Dahila. Dahila, this is Ash." Matt introduced them to each other.
"Well Ash, let's have a good time during our battle." Dahila said.
"Yeah." Ash replied.
It wasn't long until Ash and Dahila assumed their places on the battlefield. Everyone else, sat in the sidelines to watch the battle. 
"This is a two on two Pokemon battle." Dahila's assistant, who was also the referee, explained.
Then the ceiling opened up, revealing the sky and four pictures appeared on the screen. There was a picture of a snowflake, a picture of the sun, a picture of a rain cloud and a picture of sand. This is was a indicator of the weather the challengers would battle in each round. A Castform lived in the Battle Arcade and it would use the moves Rain Dance, Hail, Sunny Day and Sandstorm on whatever picture the screen had chosen. The four pictures were shuffled around for a bit and then the picture of the sun came up. That meant the first battle would take place in sunny weather. Castform used Sunny Day and changed into it's sunny form. Next Dahila sent her first Pokemon, a Ludicolo out and Ash sent out his Shiftry first.
"Bullet Seed." Dahlia told her Ludicolo.
Shiftry countered with it's own Bullet Seed.
"Shiftry, use Air Cutter." Ash said.
Shiftry fired a blade of air from it's leaves.
"Not bad, but check this. Ludicolo, use Fire Punch." Dahlia said.
"Oh no. Ludicolo knows Fire Punch." Dawn gasped, surprised.
"Since the sun is really bright Ludicolo's Fire Punch will be powered up." Brock noted.
"Dodge it, then use X-Scissor." Ash ordered.
Shiftry leaped back to avoid the flaming punch and then slashed Ludicolo in a x pattern.
"Alright Shiftry, use Solar Beam." Ash said. 
"You use Solar Beam too Ludicolo." Dahlia replied.
Because of the bright sun, Ludicolo and Shiftry didn't need to charge up to use Solar Beam and instantly fired their attacks.
The two Solar Beam attacks collided, generating a explosion. When it cleared, Ludicolo and Shiftry were still standing. 
"Ludicolo, attack with Fire Punch." Dahlia said.
"Use Focus Blast, Shiftry." Ash said.
Shiftry fired a light ball of energy from his leafy hands straight at Ludicolo, while it tried to counter with Fire Punch. A small explosion went off when Ludicolo punched Focus Blast, but it wasn't done yet.
"Now Shiftry, use X-Scissor again." Ash said.
Shiftry slashed Ludicolo across the chest before it could do anything and then Ludicolo fainted.
Dahlia was impressed with Ash's battling skills.
'I'm having a lot of fun here.' She thought.
She returned Ludicolo and sent out a brown and cream colored rabbit-like Pokemon. This rabbit-like Pokemon had long legs and long ears.
"That's a Lopunny." Dawn said. "If I recall that's what Buneary evolves into."
She opened up her Pokedex to find out.
"Lopunny, the Rabbit Pokemon and the evolved form of Buneary. An extremely cautious Pokemon. It cloaks it's body with it's fluffy ear fur when it senses danger."
Ash returned Shiftry for later use and sent Crawdaunt out.
"Ash certainly had a fine collection of Pokemon." Matt said.
It was then the screen came up with the pictures again and this time it chose the picture of a rain cloud. So Castform used Rain Dance and turned into it's rain form.
"Since it's raining Crawdaunt's water type moves will be powered up." Matt pointed out.
"Bubble Beam." Ash told Crawdaunt.
Lopunny jumped up to avoid the bubbles.
"That's the thing about rabbit-like Pokemon like Lopunny." Matt said. "They are really good jumpers."
The others agreed, especially Dawn. 
"Lopunny, Bounce." Dahlia ordered.
"Use Harden to defend yourself Crawdaunt." Ash said.
Thanks to Harden, Crawdaunt didn't take a lot of damage after Lopunny hit him.
"Bubble Beam again Crawdaunt." Ash said.
Crawdaunt fired some more bubbles at Lopunny. 
"Lopunny, use Jump Kick." Dahlia said.
Lopunny jumped into the air and kicked Crawdaunt before it got the chance to do anything.
"That's not good." Brock frowned. "Crawdaunt is also a dark type Pokemon. They're weak to fighting type moves."
"Use Jump Kick again." Dahlia ordered.
"Not this time." Ash countered. "Crawdaunt grab hold of Lopunny's leg."
Before Lopunny could kick Crawdaunt, it grabbed hold of Lopunny's leg with his claw. Crawdaunt then spun Lopunny around and tossed it away.
"Wow, I've never seen anything like that before." Dawn said.
"Ash's Crawdaunt was always good at tossing it's opponents aside even as a Corphish." Brock chuckled.
"Crawdaunt, Brick Break." Ash ordered.
Crawdaunt struck Lopunny really hard with a glowing claw.
"Lopunny's in trouble because normal type Pokemon are weak to fighting type moves as well." Tomo noted.
Dahlia wasn't about to call it quits.
"Lopunny, use Jump Kick again." She ordered.
Crawdaunt avoided the attack, causing Lopunny to take damage from the failed move.
"Now Crawdaunt, it's time to use Hyper Beam." Ash said.
Crawdaunt fired Hyper Beam which hit Lopunny head on. When the light dispersed, Lopunny had fainted. Ash was the winner.
Dahlia returned her Lopunny and walked over to him.
"Well Ash." She said. "That was a fun battle and I was impressed with your battling style."
"I had fun too." Ash replied.
The referee came over with a cushion in their hands. 
"So then Ash, as proof of your victory I present to you the Battle Arcade plaque." The golden plaque had a picture of the Battle Arcade. Ash only had to get two more plaques.
After the challenge was over, the gang waved goodbye to Matt and Dahlia and headed to their next destination.
