Y/n's Unova adventure

The mystery of the Nacrene gym, and Y/n and Ash's second gym battle begins

Our heroes arrived at Nacrene city and discovering that the Nacrene Gym is inside the city museum, our heroes meet a very scared man. His name is Hawes, and it turns out that he's soon to become co-curator of the museum. He claims to have seen ghostlike apparitions recently, just as the museum is about to launch what is called the Secret Artifact Exhibition.

Palutena decided to help Hawes out by scanning the museum with her aura and something caught her attention. She entered the museum scanning the exhibits, she spotted something interesting.

"Hawes, is this mask part of the artifacts you ordered?" Palutena asked.

"Actually no, i thought it was a bonus."

"Well you thought wrong, this mask is the real deal." Palutena explained." The Yamask must had been brought in along with the artifacts and had dropped it mask, by mistaking it for a replica and putting on display, you angered it." Soon

"I see, i  feel bad for mistaking it's mask for a replica."

Y/n sent out his Lucario who used foresight, after some looking he managed to reveal the Yamask.

Curious, Ash pulled out his Pokedex to scan the new Pokemon.

"Yamask, the Spirit Pokemon. Yamask is a Ghost-type Pokemon that wanders the ruins of ancient civilizations." The Pokedex beeped.

Hawes opened the glass display and Yamask took it's mask back, Hawes apologized to the spirit Pokemon who accepted and left peacefully.

Soon Hawes's wife Lenora and the Nacrene city appeared, after she was informed of what happened, she accepted Y/n and Ash's challenge. 

Soon they were at the back of the museum where's there's a library, after pulling a book that lead to the gym, Y/n and Lenora got ready.

"Lucario battle time!"

"Lillipup lets go!"

Ash pulled out his Pokedex to scan the new Pokemon

"Lillipup, the Puppy Pokemon. The long hair covering Lillipup's face is an excellent radar, which senses conditions in the surrounding area."

"Lillipup roar!"

Lillipup's body becomes outlined in a crimson aura and it yells loudly, releasing invisible shock waves from its mouth that expand outward. The yell has enough force to push Lucario next to his trainer as Y/n's Milotic was forced out.

"Lillipup return." Lenora recalled the puppy Pokemon. "Watchog go!"

"Watchog, the Lookout Pokemon, and the evolved form of Patrat. Watchog's body contains luminescent compounds, which allow its eyes and stripes to glow." Ash's Pokedex to beep.

"Mean look!"

Watchog closes its eyes and its body becomes surrounded in a dark purple aura. It then opens its eyes and they glow bright red. The purple aura then rises into the air and forms an eye with a black pupil. The eye then becomes surrounded in a magenta aura, and multiple smaller eyes with a magenta outline appear around it and spread throughout the battlefield. Milotic's body then becomes surrounded in a magenta aura.

"So that's your plan huh? Not bad at all." Y/n smirked." But it's gonna take more then that to rattle me, hydro pump!"

"Dodge and sand attack!"

Milotic fired a blast of water at Watchog who dodged and throws sand at Milotic using its hands. The attack hit, slightly blinding  Milotic. The tender Pokemon suddenly glowed red slightly.
