The Devil's dungeon.
"I'm getting worried about Discord," Trixie whispered, to Starlight.
"Me, too," Thorax nodded, "he's acting strange."
"Discord...acting strange," Starlight said.
"I mean, stranger then normal," Trixie replied.
She motioned at Discord, who was staring at the three as if they weren't there, muttering to himself.
"Da-dee-la!" he said, "I'm Opposite Discord, and I want to Orange you glad I've changed? If you ever need a little chaos in your act, let me a trick that'll turn Celestia's castle into cheese. Do you think it's a "gouda" idea? "I'm going to need more popcorn...I gotta have more cowbell!"
"Should we be worried?" Thorax asked.
"I don't know," Starlight replied.
Las Pegasus.
"So you two are from a whole other world," Rainbow Dash said, as she, Pinkie Pie and the two brothers walked around Las Pegasus looking for the last four members of the Mane Six.
"Yep," Cuphead replied, "and the being that corrupted you and your friends is called The Devil and he's from the same world that me and Mugman are from."
"That's why they came here," Pinkie continued, "To help free our friends and defeat The Devil."
"I guess that makes sense," Rainbow Dash said, slowly trying to wrap her head around what she had just been told.
The Devil's office.
"Still think it was a good idea to send Sloth?" Wrathlight Sparkle asked.
"Don't get snippy with me," The Devil snapped, "how was I supposed to know that pink pony had a way to get past my powers."
"Anyway," he continued, "it's time to pick one of you to face the mugs and their allies."
"Pick me, pick me!" Applepride cried, "please pick me."
"No, pick me," Flutterenvy jumped in, "I'm can beat them better than her."
"I'll do whatever you want, my lord," Lustery swooned.
"For the love of...." Wrathlight Sparkle sighed, "SEND ME! I'm more qualified to destroy them than these idiots!"
"Applepride," The Devil announced, "you're next, please try to last longer than the first two."
The other three sins didn't react, they had, by now, given up questioning their master's choices.
"Oh, thank you," Applepride cheered, "I won't let you down."
"I hope you don't" The Devil replied.
Like before, The Devil snapped fingers and Applepride vanished.
Las Pegasus.
"I don't know about you guys," Rainbow Dash said, "but searching for me and Pinkie's friends is making me thirsty."
"I hear that," Mugman nodded, "all this searching is quite draining."
"How about that place," Cuphead suggested, pointing out a nearby tavern, the name The Drunken Demon, hung outside.
"Sounds like a plan," Pinkie nodded.
With that, the four friends headed into the tavern.
Once inside, they all headed to the bar.
"What can I get you four?" the bartender, asked.
"Two apple ciders for us," Rainbow Dash replied.
"We'll have whatever you've got," Cuphead added.
The bartender nodded and hurried off to fetch their drinks.
The four friends took a seat at a table.
Moments later, a figure brought the four drinks to the table.
While Cuphead and Mugman were enjoying their drinks and while nopony was looking, the figure put a drop of a mystery liquid into the brother's heads.
Cuphead began to feel wheezy and light-headed, "Whats in these drinks?" he asked, his vision starting to distort.
"Somepony must have spiked their drinks," Pinkie Pie exclaimed.
"Hey!" Rainbow Dash called, to the figure who had brought them their drinks, "what did you put in those drinks?!"
"Oh," the figure, who had brought the drinks over, replied, "I just added my special ingredient."
"Hmmm," Pinkie said, looking hard at the figure, "you look familiar."
The figure laughed, manically, "I guess I can't hide anymore," she smiled.
With that, the figure throw off her disguise, revealing herself to be.....
"Applejack?!" Rainbow Dash cried.
"That's Applepride to you," Applepride replied, "and thanks to my triple strength zap apple cider concoction, Cuphead and Mugman won't be a problem."
"You made a big mistake," Pinkie declared, "you've got to deal me and Rainbow Dash."
Applepride laughed, "the two of you won't be enough to beat me," she smirked.
Here's a real high-class bout!
And begin!
Pinkie Pie pulled out her party cannon and fire off a few blast at Applepride.
She, with rapid reaction, dodged her attack.
Before she could retaliate, Rainbow Dash flew at her, trying to create a whirlwind to knock her off her hooves.
But Applepride, manage to stop her before she could ever start the whirlwind, hurling a container of something sticky at her.
"What is this?" Rainbow Dash asked, struggling against the substance as it hardened.
"That would be my Cider Cement," Applepride smiled, "don't worry you won' t be stuck forever," she continued, "just long enough for me to deal with you and your pink friend."
She turned to face Pinkie Pie, "now to finish you," Applepride said, "this shouldn't take long."
The Devil office.
"Whats the reason you call us here?" Flutterenvy asked.
"I would like to know too," Lustery nodded, "ever minute I spend away from my lord is torture."
"The reason I called you two here," Wrathlight Sparkle replied, "is because I'm getting tired of our master's tactics."
"So what do you suggest we do?" Flutterenvy inquired.
"I suggest we go and take on the two mugs and their allies all together," Wrathlight replied, "no more of this 'one at a time' nonsense."
"You have a point," Flutterenvy nodded, "I'm in."
"Well I don't know," Lustery said, "I hate to go against our lord and master."
"I'm sure that the master would reward you for doing this," Wrathlight added.
"I'm in," Lustery replied, quickly.
"Then it's settled," Wrathlight smiled.
She began explaining her plan to the other two sins.
Back to the battle.
Pinkie Pie had managed to free Rainbow Dash from the cement trap, using hot sauce, and the two were now facing down Applepride.
"Give up," Rainbow Dash declared, "your finished."
"Yeah, you meanie," Pinkie nodded, "give up."
Applepride laughed, "I can't beat me I'm unstoppable!"
"Whatever," Rainbow Dash replied.
Before Applepride could react, Rainbow Dash flew at her, knocking her off her hooves.
Pinkie follow with a quick blast of sticky toffee from her party cannon.
With Rainbow Dash, delivering the finishing blow.
Knockout!
Applepride had been defeated.
"What the hay?" she asked.
"Applejack!" Rainbow Dash cried, glad to have her friend back.
"Welcome back," Pinkie added.
"Does somepony wanna tell me what the hay is going on?" Applejack said.
Pinkie and Rainbow Dash were about to explain, but they were interrupted as Cuphead and Mugman who were recovered from their drunken stupor.
"What happened?" Cuphead moaned, "I don't remember anything."
"Me nether," Mugman blubbed, though his disorientated haze.
"Nice to have you two back," Rainbow Dash said.
"Did we miss anything?" Mugman asked.
Then Cuphead and Mugman noticed Applejack.
"We missed the whole fight?!" Cuphead exclaimed.
"Well anyway," Mugman said, "good to see that you manage to break The Devil's hold over your friend."
The Element of Honesty has joined the party
The Devil's office.
"Blast it!" The Devil fumed, "even when those mugs are out, those ponies find a way to defeat my sins!"
"I guess, its time to pick another sin to send," King Dice suggested.
"Fine," The Devil nodded.
"Sins to me!" The Devil commanded.
But the last three were nowhere to seen.
"Great," The Devil growled, "just what I need, next time I make minions I'll make incapable independent thought."
Back with the heroes.
Rainbow Dash and Pinkie Pie had finished telling Applejack who Cuphead and Mugman were and why they had come to Equestria.
"Well," Applejack said, "we'd better get searching for Twilight, Fluttershy and Rarity."
"That could take ages," Cuphead replied, "where do we even start looking?"
"Oh, I don't think you'll have to look that far," a voice answered.
All the heroes turned and gasped.
Here comes some new challengers!
