The Phantom Mutant

It was a normal day in Jamaa when Apophis had one of the craziest ideas ever.
Everything was normal. The usual scammers were trying to fool the pure Jamaasians, but not many people fell for it.
The ones that did went to others begging for "rare" items, and the cycle began anew. There were a few heroes taking a vacation, though, sunbathing in Crystal Sands. Frost and Mia were laughing at the funny pictures they had found on the paw-ternet and exchanging bad puns about Jamaasian culture.
Zios, or at least the sun, burned brightly in the sky, its rays nurturing the plants dotting Jamaa.
"Hey, Jammers, don't forget about the Photo Booth contest!" a blue macaw squawked as it went about its daily flight, and dropped an organic paper envelope... right on Frost's head.
"Ow!" cried Frost as the bruise throbbed on her head. Mia laughed at her grumpy expression, and after nearly laughing to death clawed the troublesome envelope open.
The note instead was a gold-leaflet with a membership sign in the corner.
It said the same thing as what the macaw had said.
"That was.... not needed." Frost mumbled.
Mia almost fell into the bay laughing.
Frost kicked her to help her fall in.
"Spppppppt!" Mia spluttered, spewing water out of her mouth as she clambered out of the sand.
Now it was Frost's turn to almost laugh to death.
Water dripped from Mia, so she shook her fur like a dog. Frost didn't mind, of course, because she was actually a really good swimmer. A little shower didn't bother her.
Suddenly, Marco somersaulted out of nowhere, and crashed into Mia.
"Oh, hi. I was doing some gymnastics when Lisa told me with a note that you two need to go to the Phantom Palace and challenge Apophis. I don't know why." Marco said. The paint on his feathers shimmered, and he disappeared.
"Um... I guess its time for an adventure!" Mia said awkwardly.
"Isn't that copyright infringement on 'Adventure Time'?" Frost replied.
"Whatever. Lets just go make some mythical snake pancakes."
"You never could have said it better!" Frost said, but at those words the sky darkened. Thunder rumbled, and phantoms dove down from a hole in clouds.
"Jeez, those creatures just love a dramatic entrance." Frost muttered.
Suddenly, the ground opened up in a chasm, and swallowed the two of them.
"AHHHHHHH!"

They awoke in the onyx palace of the phantoms, dark and dreary. Both of them expected to be surrounded by phantoms, but instead... none were around, not even a trace of the phantoms that were invading.
"That's odd.. they usually tally what phantoms were out of the palace!" Frost said.
Mia looked up at the bone chandeliers in awe at the beautiful yet ugly architecture.
Wisps of icefire floated around, which was considerably creepy considering how dangerous icefire was. One touch and you got a severe burn.
Suddenly, a hiss came from the throne room.
"We need to see what has happened to them!" Mia said, taking charge. Frost muttered something under her breath, but followed the brown arctic wolf.
When they got to the black thrones, they saw a hideous monster.
The Phantom Queen was still normal, but the Phantom King had fused with his minions (every single one) to make a serpent with robot legs. Apparently, the roboticized minions hadn't been spared.
"Whatever you are, monster, surrender or face an embarrassing beat-down!" Frost cried, unsheathing her claws.
"You aren't in a position to demand anything, half-phantom."the monster snarled, its wrinkly skin thrumming. The words seemed to radiate from the monster, since no phantom had a mouth.
"You beast! Why, you're nothing more than a mutant!" Mia shouted. The monster seemed unimpressed.
"Well, you see, I made myself into the ultimate fighting machine using the powers of a stolen Mira Feather. However, phantom production has been stalled until I release this form." the monster said.
Suddenly, the palace shook, and turned into a battleground.
That was because the monster charged them.
Because it seemed like a bull, Frost stepped aside at the last minute, but the eye followed her movement and blasted her with a precise laser.
Frost was knocked off her feet.
The robotic legs fired rockets that Mia barely dodged, and it snake half of its body whipped Frost as she lay, stunned, on the cold floor.
The phantom half's legs skittered on the smooth floor like spider legs, and its claws swiped at Mia's paws.
It seemed invincible, when a storm wolf charged out of nowhere and smacked the phantom on the face.
"Die, demon, die!" she cried.
"Victory!" cried Frost. Mia thought Frost was proclaiming victory for them when she realized that was the arctic wolf's name.
"Vicky, use your storm powers! I'll do the combo with you!" Frost said, getting up on all four paws.
Mia watched in awe as a stormcloud popped out of nowhere, then started to snow AND shock the phantom with lightning.
Icefire raged across the floor, Frost's will triggering their powers.
The creature wailed as the icefire froze it and devoured it, the phantoms bursting out and the phantom king half-dissipating.
"You will pay, heroes of Jamaa!" he shrieked, then all was still as the little phantoms tended to their master.
"So these are the phantoms you spoke of? Are you sure Zios took care of my sister Snow?" Victory asked Frost.
"I'll explain later. Right now, we need to leave." replied Frost.
They teleported together back to the beach, talking about what had happened and how to steal/ neutralize the Mira Feather the phantoms possessed.
