"ASH! SERENA! GUYS?!" a voice yelled. I was woken by a yell. I saw a human looking at me. He had blonde hair and glasses, and he looked distressed. I stayed in place, staring back at the man. The pokemon I saw sleeping earlier surrounded the table, leaving no escape. 

Three other humans plus Pikachu and a Braixen ran into the room. I think one of these people is Pikachu's trainer.

"What is that and why is it in here?" The blonde with glasses said. The smaller girl with similar blonde hair kneeled down to look at me. He eyes lit up and she patted my tail.

"So fluffy!" she said.

The other three humans just looked at me with concern.

"Is it an Espeon?" The human with black, spiky hair asked. 

"I don't think so." The woman with long brown hair and the man with glasses said. He pulled out a familiar looking red square.

"No data. No data. Unknown Pokemon. Last sighting: June 8th."

"Woah!" the Human with the black hair shouted. "A new Pokemon!" 

Pikachu jumped from his shoulder and said some things to the other pokemon. They relaxed and walked away. The girl with brown hair crawled under the table and picked me up. Her aura was friendly, so I let her. 

"My name is Serena!" she said. "That's Climont, Bonnie, and Ash!"

Timeskip cuz i'm too lazy

The group sat in front of the black metal box. Serena called it a TV. The red matal square was called a pokedex, and the white and red orbs were Pokeballs. Pikachu caught me up with some human things. 

The TV came to life, displaying a man in a white coat. Ash said something of him being a person named Professor Oak.

"Hello Ash! Serena! Bonnie! Climont!" he greeted. I snuggled a little in Serena's arms.

"Hello professor!" Serena greeted. "We found a new pokemon, and we were wondering if you knew what it was. The pokedex had no data about it."

Serena put me down on the floor and I faced the camera.

"Interesting!" Oak exclaimed. "I've never seen anything like this before!" He studied me a little.

"From the looks of it, it seems very similar to an Espeon. It has many features from many of the Eeveelutions! I think we can say that this is a undiscovered evolution of Eevee! Do you know what type it is?"

Ash shrugged. 

"We don't. But it's a little see-though, and there these little orbs things floating around. It's eyes glow too."

"It may be ghost type. I think we should name it!" Oak exclaimed. 

"Yeah!" Ash shouted. "But what should we name it?"

"How about Ghasteon?" Oak suggested. The group was silent for a few moments, before Serena chimed in.

"I think it's the perfect name!"
