A/n: hey! I modified the song a bit just so it fit the scenario, I also cut a little piece of the beginning out!
Happy Reading!

"What the hell do you keep looking back for! Your not regretting this are you?" Hades said loudly.
You guys made it across the bridge and were about to walk into Auradon.
"No- No, of course not," you said, "I just- I feel like there something" you stopped and looked at the water.
The waves peacefully swayed in a steady rhythm.
"I think it's time to give this a try" you said putting a hand on your amulet, "It's real, I feel, make itself reveal" you said, your eyes glowing yellow.
And from your amulet, a thick blue smoke arised covering the air with, then it all plunged into the sea, searching for the presence you felt.
**********
Meanwhile under the sea...
Uma had been following you guys and hearing your plan.
You almost caught her a couple of times, since you kept looking back.
And you wouldn't stop looking.
She heard you cast that spell and swam as deep as she could, but the smoke kept coming.
So she used her own magic shell to cast a protective bubble around her.
But the smoke cracked the bubble, your magic was too strong, and started to slowly enter and suddenly it disappeared.
***********
Back on the surface...
"There's nothing there, come on" Hades said.
You looked at the water for a few seconds then gave in, "fine" you snapped you fingers lifting the spell.
You and Hades turned and looked at the arc to Auradon.
You walked in, 'this is actually happening' you thought, 'after so long'
The salty ocean air left your nostrils and was replaced with sweet and fresh air.
Auradon was beautiful up close, there was so much green covering rock walls of the huge patio(type of thing, y'all know what I mean? Where they sing break this down?)
"Here it is, our KINGDOM!" Hades boomed extending his arms and doing a little spin.
You blushed, 'our kingdom?' you thought and laughed as he took your hand.
"Welcome...my Queen" he said now putting his arm around you as you two walked through a tunnel.
"It's really quiet" you said thoughtfully, "ah Little Miss Evil put the whole kingdom to sleep!" You laughed, "she just made our job a whole lot easier!"
You guys strolled confidentially through Auradon, laughing here and there when you saw the citizens sleeping, when a certain building caught your attention.
"The Museum of Cultural History?" You said, "this is where Miss Evil stole the crown and scepter. Let's take a little detour, and see what else is in here"
"Really?" Hades sighed.
"Fine, you can keep going to Beasts' Castle, I'll catch up" you said.
He gave you a 'are you serious' look.
"I'll be quick, a few extra magic wouldn't hurt to have" you shrugged parting ways.
You entered and heard a loud snore, you looked to where it came from and saw the security guard fast asleep.
You wondered through the rooms, the museum was home to many items like King Triton's Trident, Aladdin's magic lamp and carpet, just to name a few.
You even passed through a room titled, "Gallery of Villains" where they had all these realistic statues of the VKs parents.
Then you found a room where the Fairy Godmother's wand was nearly displayed.
"A little extra magic wouldn't hurt anyone" you restated and reached out of the wand but stopped.
"Hm?" You felt it, the protection around it.
And even though the entire kingdom was asleep, you didn't want to be sloppy and leaving the wailing of the alarm on, so you put a silencing spell over, then focused on breaking the force.
Your magic worked over the good and the protection over the wand broke, leaving it open for you to take.
You smiled at your work and took the wand, carefully in your hands.
Just as you took and turned around to leave, a cloud of pink smoke appeared and disappeared to reveal, Sleeping beauty's daughter.
"Excuse me, who do you think you are?" She questioned with a sassy tone, sassy-er than Hades ever could.
'well I was bound to have a conversation with her sooner or later' you thought, and opened your mouth to speak but she interrupted.
"What are you doing here? Everybody's suppy to be sleeping!" She shrieked the last part, then gasped, "your here with Hades! You were the one trying to escape with him last week!"
"Correct!" You said casting a shut up spell with the wand, but she deflect it with the scepter.
"Did you just try to spell me?" She asked offended, "do you not know who I am? I'm your queen, you filthy-"
"Oh, my humble apologise, your highness" you got down on one knee and bowed.
It was time to do a little brain-washing.
"I believe we've never met before, so let me introduce myself" you said looking up, "my name is Y/n, my father is the Chernabog" you got up, "I don't think you've heard of him, but he's not important"
"I've been following your story, and I wholeheartedly agree that you should be Queen, in fact you ARE a much better queen than that," you rolled your eyes, "Mal"
"Right?" She said with a smile, "I'm to much better than her, at everything!"
You shook your head in agreement.
"So, what would you say if I'd," you paused searching for the right words, "assisted you in your ruling over your kingdom, I'm just, such a big admirer of you, you just took matter into your own hands, you took action"
Audrey was now interested in what you were saying.
"Besides!" You suddenly exclaimed, "who wouldn't want to be as evil as me? The daughter of the most feared villain, so feared that no one dares to speak of him anymore. I can teach you."
Audrey now wasn't so convenient.
"Look, the only way your gonna get what you want is by taking it, and if you can't take it, break it" you said trying to win her back over.
Audrey was gonna say something when you interrupted,

"Look at you, look at me, who do you wanna be? Hmm?"

"I was once like you my child
Slightly insecure
Argued with my father and
Thought I was mature"

"But I put my heart aside
And I used my head" you bobbed her on the head lightly.

"Now I think it's time you learned
What I'm about to say"

"Don't you wanna be evil like me?
Don't you wanna be mean?
Don't you wanna make mischief your daily routine?"

"Well you can spend your life attending to the poor
But when you're evil doing less is doing more"

"Don't you wanna be ruthless and rotten and mad?
Don't you wanna be very, very good at being bad?"

"I have tried my whole life long to do the worst I can
Clawed my way to victory
Built my master plan
Now the time has come my dear for you to take your place
Promise me you will try to be an absolute disgrace"

"Don't you wanna be evil like me?
Don't you wanna be cruel?
Don't you wanna be nasty and brutal and cool?"

"Now that you grabbed that crown that's when your reign began
Who wants an evil queen without a sack of sins?"

"Don't you wanna be heartless and hardin' as stone?
Don't you wanna be finger licking' evil to the bone?"

"This is not for us to ponder
This was preordained
You should learn to rule, my child
Freedom soon regain
Mistress of the universe, powerful and strong"

"Audrey, hear me
Help me, join me
Won't you sing along?"

She thought about it, then joined you, you smiled,

"Now we're gonna be evil it's true

Never gonna think twice"

"And we're gonna be spiteful" she said.

"Yes, spiteful
That's nice" You bobbed her nose.

"In just an hour or two
I'll teach you all the rules"

"This Broadway act is going out on tour"

"If you wanna be evil and awful and free
Then you should thank your lucky star"

"That you were born the girl you are
The best friend of an evilicious queen"

"Like me!" You laughed at the load of BS you just made up.
And she bought it cause she said, "ok, teach me how to have everyone like me"
"

Perfect!" You said, extending your hand, "how about we shake on it to make it an official partnership?"
Your amulet glowed blue.
She shook you hand and froze.
She stood completely still.
You smiled, "stranger danger" you laughed at the frozen girl.
You had spelled her, leaving her petrified and unable to move.
"I'll take care of this of you" you took the crown off her head, "oooo, and this too" you said tucking the wand in your sleeve and taking the scepter.
"And how about a little update to this crown?" You magically morphed into a darker crown.

"Perfect!" You said, your make up became darker as you placed it on your head.

"ta ta!" You laughed and waved at the Audrey.
And with your newly attainted power, a black and blue cloud transported you to Hades' location: Beasts' Castle.
