Several days had passed since Rainbow beat Yusei, and now Sunset was starting to feel the urge to turbo duel.

Later that day, the girls popped on the TV at Applejack's house to watch Rainbow battle a new turbo duelist named Sky Stinger.

(At the turbo stadium)

"Let's ride!" said Rainbow and Sky.

Rainbow Dash LP: 4000

Sky Stinger LP: 4000

Rainbow Dash SC: 1

Sky Stinger SC: 1

Turn 1: Sky

"I'm going first!" said Sky. "I draw! First, I set the Pendulum Scale with Speedroid Passing Rider and Speedroid Domino Butterfly. Now I can Pendulum summon any number of monsters that are between levels four and seven."

"I know," said Rainbow. "Just get on with it."

"Just remember, you asked or it," warned Sky. "I now Pendulum summon Speedroid Den-Den Daiko Duke, Speedroid Terrortop, and Speedroid Pachingo Kart. Then I'll activate my Terrortop's effect and add another Speedroid monster to my hand, like Speedroid Razorang! And since it's now in my hand, I can Pendulum summon my Razorang. Next, I will normal summon Speedroid Red Eyed Dice. Next, I'll tune my Red Eyed Dice with Pachingo Kart in order to Synchro summon Hi Speedroid Hagoita! Then, I'll tune Den-Den Daiko Duke with my Ohajikid and Synchro summon Hi-Speedroid Kendama! Now I activate my Daiko Duke's effect, by banishing him, I can special summon a Speedroid tuner monster from my graveyard. I choose Red Eyed Dice, then I'll tune him with my Razorang to Synchro summon Hi Speedroid Chanbara! Let's see ya top that."

Rainbow Dash SC: 2

Sky Stinger SC: 2

Turn 2: Rainbow

"You got it," said Rainbow. "I play the Speed Spell – Overboost, so I gain six Speed counters.

Rainbow Dash SC: 8

Sky Stinger SC: 2

Now I can play The End of the Storm Speed Spell!"

"Say what?!" cried Sky.

Rainbow Dash SC: 0

Sky Stinger SC: 2

"Just remember, you asked for it," said Rainbow imitating Sky. "So say goodbye to all your monsters, and 900 life points."

Rainbow Dash LP: 4000

Sky Stinger LP: 3100

"Damn," said Sky.

"I'm not done," said Rainbow. "I now discard my Quillbolt Hedgehog to special summon Quickdraw Synchron in attack mode. And since there's a tuner on my field, I can special my Hedgehog back to the field. Then I'll tune them together to Synchro summon Junk Archer! Next, I'll summon Deep Sea Diva, which activates her ability, allowing me to special summon Spined Gillman from my deck. I now tune my Diva and Gillman together to Synchro summon Accel Synchron! Since I have a tuner on the field, I can special summon Boost Warrior in defense mode. Now I activate my Synchron's effect and send Synchron Explorer from my deck to the graveyard. Now I can either increase or decrease my Accel Synchron's level by my Synchron Explorer's level. I think I'll reduce my Synchron's level. (Accel Synchron Level: 5 – 3) Now I'll tune my Synchron with Junk Archer to Synchro summon Stardust Warrior! And thanks to my Boost Warrior's effect, I can increase my Warrior's ATK points by 300. (Stardust Warrior: 3000 – 3300) Stardust Warrior, attack him directly!"

"Ah!" cried Sky.

Rainbow Dash LP: 4000

Sky Stinger LP: 0

"That's it! The duel is over!" said the MC. "Rainbow Dash wins again!"

"Oh yeah!" said Rainbow as the crowd cheered.

"Shoot," said Sky.

"Alright Rainbow!" said Pinkie.

"Ho-wee!" said Applejack.

"That new deck of hers is awesome," said Twilight.

"Totally," said Spike.

"I completely agree," said Rarity.

"I kinda feel bad for Sky Stinger," said Fluttershy.

Sunset couldn't sit still anymore. "I want to get to that level!"

"You wanna duel Rainbow?" asked Pinkie.

"Not now," said Sunset. "But someday. I mean I can ride just as good as Rainbow can."

"Absolutely, darling," said Rarity. "You could so ride against them."

"So what we waiting for?" asked Applejack. "Let's you and me get out on the track and practice! I got a new duel runner I've be waiting to try out."

"Alright!" said Sunset.

Pinkie drove the girls and Spike to the practice track in her Hummer while Sunset and Applejack rode on their duel runners. A minute later, Flash drove up. "Hey girls!" he called. "What's going on?"

"We're kinda… training Sunset," replied Twilight.

"For what?" asked Flash.

"She wants to duel Rainbow one day," answered Twilight. "So we're helping her push her limits so she can ride in the pro turbo league."

"Cool," said Flash. "Mind if I watch?"

"Nope," answered Sunset. "I could use some additional support."

"Anytime," said Flash as he hugged her.

"Thanks," said Sunset. She then got back on the track.

The girls, Flash and Spike sat in the stands while Sunset and Applejack headed to the starting line.

"Are ya ready?" asked AJ.

"You bet," answered Sunset. "Don't go easy on me."

"Wasn't planning to," said Applejack.

"Go Sunset!" called Flash and Pinkie.

"Yay," said Fluttershy softly.

"Let's ride!" said AJ and Sunset.

"Yeah, woo-hoo!" said Spike.

Sunset LP: 4000

Applejack LP: 4000

(A few turns later)

Sunset LP: 1000

Applejack LP: 900

"Sacred Phoenix, attack!" said Sunset.

"Dog gone," said AJ as her points went to zero.

Sunset LP: 1000

Applejack LP: 0

"Alright!" said Twilight and Fluttershy.

Spike barked in joy.

"Way to go, Sunset!" said Flash.

"Amazing," said Rarity.

"Woo!" said Pinkie.

"Good job, Sunset," said Applejack.

"Thanks, Applejack," said Sunset.

"That was amazing!" said Pinkie.

"You were great," said Flash.

"A few more duels and you'll be dueling Rainbow in no time," said Twilight.

"Impossible," said a voice. The girls looked behind them to see a man dressed in a cobalt uniform outlined in yellow highlights. He had dark blue hair and wore deep red sunglasses. "Until you've gone through what they have, you won't be able to duel at that level."

"Who do you think you are, telling my girlfriend what she can and can't do?!" asked Flash.

Spike growled at the stranger.

"The only way you could get up to their level, Sunset, is to find the Synchro Solution," said the man.

"The Synchro Solution?" asked Sunset.

"What's that?" asked Fluttershy.

"Who exactly are you anyway?" asked AJ.

"You can call me Vizor," said the man.

"Oooh, cool," said Pinkie. "Hi, Vizor, I'm Pinkie…." Vizor gave Pinkie a serious look. "N-never mind."

"So, Vizor," said Sunset. "Just what is this… synchro solution?"

"You'll just have to duel me and find out," said Vizor.

"Wait, Sunset!" said Flash. "How do you know you can trust him?"

"You can't," chuckled Vizor. "Where I come from, trust something a person has to earn."

"Just like that?" asked Twilight. "You expect us to listen to a complete stranger?"

"And you even told us we can't trust you!" added Pinkie. "Make up your mind!"

"I understand what you're saying," said Vizor. "But like it or not, I'm the only one who can show your friend the Synchro Solution, and show you how Yusei and Rainbow got to the level they're at."

"Okay…" said Sunset.

"Are you sure about this?" asked Fluttershy. "Because I'm not."

"Nor am I," said Rarity.

"Me neither," said Spike.

"For some reason, I believe what he's saying," said Sunset. "I think I can trust him."

"Okay," said Flash. "Just be very careful."

"I will," said Sunset. "I promise."

"Hold on, Sunset," said Rarity. "Here, take this card."

"Gem-Knight Obsidian?" asked Sunset.

"Take it for good luck," said Rarity.

"Thanks a lot, Rare," said Sunset.

Sunset got back on her runner and shuffled Rarity's card in her deck. A few seconds later, Vizor road over on a deep blue sharp-pointed duel runner that had one large wheel in the back, and two small ones in the middle.

"Nice ride," said Sunset.

"Thanks," said Vizor. The two then headed for the street.

"I have a bad feeling about this," said Fluttershy. "A really bad feeling bout this."

"I wish we could see their battle," said Flash.

"Maybe we can," said Twilight. "I can tap into their frequencies so we can watch the duel on my laptop."

"Way to go, Twilight," said Applejack.

(On the street)

"Try to keep up, Sunset." Vizor accelerated and raced off.

"What the?" asked Sunset. "I thought he wanted to duel, not race."

"Is this guy challenging Sunset to a race?" asked Applejack.

"What?" asked Flash.

"Go Sunset!" cheered Pinkie.

Sunset raced after Vizor, but he just went faster. "Woah! Okay," said Sunset in a competitive tone. She shifted to her next gear and shot after Vizor.

As Sunset caught up, Vizor smiled and hit his nitrous booster. His runner tore down the road.

"Wow," said Fluttershy. "He's fast."

"Yeah? Well so is Sunset," said Flash.

"Can you keep up?" asked Vizor through a speaker on Sunset's runner. "You'll never to get Rainbow's level at this snail pace speed."

"Oh really!" said Sunset as she pressed her own nitrous button. A couple seconds later, she caught up to Vizor.

"Alright!" said Pinkie and Fluttershy.

"Well done, Sunset," said Vizor. "Now it's time for step two. I activate Speed world 2!"

"Duel mode engaged," said a robotic female voice. "Autopilot activated."

Signs then popped up on the sides of the road and a voice called out. "A turbo duel is about to commence! All none dueling vehicles must vacate the combat lane immediately!" All the cars, vans and trucks moved off the lane.

"Let's ride!" said Sunset and Vizor.
