That night...

Mewtwo emerged from his PokeBall and saw Ash sleeping with Pikachu peacefully, just like on the previous night. He breathed a sigh of relief and headed towards the roof, where he saw Shadow waiting for him. He noticed that her purple eyes glistened in the moonlight just like he told her. She smiled when she saw him.

"Great, you came!"

"Why wouldn't I? Is something wrong?"

"No, nothing's wrong! I wanted to get your opinion on something."

He sat down next to her, waiting for her to speak. She looked to the moon again.

"Have you ever wished you were...human?"

She blushed when she finished her sentence. Mewtwo, however, looked at her in wonder.

"Like, born human or just for the experience?" He asked.

"Both."

"Sometimes...Why?"

She looked at him. "Do you know the move Wish?"

"I'm a copy of Mew; I can do anything." (Again, I know this isn't true, but for the sake of the story, just go with it.)

She held out her hand.

"Hold my hand and look at the moon."

He blushed and looked at her, which caused her to smile.

"Don't be shy...just take my hand!"

"What's the point of all this? Why did you call me up here?"

She put her hand back at her side and looked into Mewtwo's suspecting eyes. "I thought that...you would want to know what it's like to be human before we meet Arceus."

Mewtwo still had a suspicious look on his face.

"So, let me get this straight: you want to turn both of us human using Wish...are the effects permanent?"

"There's only one way to find out."

"All right then, but prove to me that it works."

Shadow sighed and looked at the moon. Mewtwo was skeptical as she used Wish. But to his surprise, something actually started to happen. He saw Shadow's entire body glow in a blue light, and what he saw afterwards made him rethink his skepticism. Shadow had actually turned human; she had light skin and purple eyes, but she was wearing a black tanktop with a black skirt and matching leggings underneath. She had dark purple lipstick and purple long hair that went a little past her shoulders. Mewtwo was amazed. Shadow noticed his stare and giggled.

"See? Didn't I tell you it would work?"

"No. You just wanted to try it. And now that I see that it works, I guess I'll try."

Shadow watched as Mewtwo used Wish while looking at the moon. He was also glowing in a blue light as he transformed. Shadow was amazed when she saw Mewtwo's human form. He was wearing a purple spandex shirt that was short-sleeved that showed his muscles. He wore matching shorts with purple shoes. His hair was the same color as Shadow's but he had spiky hair. Again, Shadow looked at Mewtwo's muscles he had gained from training with Ash, which resulted in a blush.

"So? How do I look?"

Shadow tried to keep her composure. "You look really nice."

Mewtwo smiled and walked towards her. "You look stunning." Mewtwo could see her light skin turn a little shade of red despite the fact that it was nighttime.

"We should stay like this when we aren't battling," Shadow suggested. Mewtwo nodded as they sat down and looked over the ocean surrounding Ferrum.

"I never asked you how you became like that," said Mewtwo.

"Like what?"

"How did you become Shadow Mewtwo?"

Shadow looked down in fear. Mewtwo saw this and took the hint.

"Never mind. You don't have to tell me."

Shadow looked at Mewtwo.

"Thanks. I just don't want to relive the pain."

"That's understandable."

They teleported back inside the hotel room just as dawn was on the horizon. They saw Ash start to stir.

"So, how do we turn back into our original forms?" Mewtwo whispered.

"Use Wish in the sunlight. Use it in the sun or moonlight and you can transfer at will." Shadow responded. Just then, Ash sat up.

"Wake up, Pikachu, it's time to-who are you?"

He caught sight of Shadow and Mewtwo and looked at them in curiosity.

"Wait a minute...purple hair and purple clothes...purple eyes...Mewtwo, is that you?"

Mewtwo nodded.

"How did you turn human?"

"Just something Shadow taught me."

"Ash! Ash, have you seen Shadow?"

Just then, Serena ran in and saw Shadow, Ash, and Mewtwo.

"Who are they?"

"The guy is Mewtwo. The girl is Shadow."

"But how did they turn into humans?"

"Apparently Shadow taught him..."

"Interesting...but anyway, we have another battle later today. I'm fighting someone named Flannery while you fight some Sinnoh trainer named Paul."

"OK! Let's go!"

Mewtwo and Shadow used Wish and converted back to their original form before being returned to their PokeBalls.

That afternoon...

Ash and Serena had won their respective battles and decided to go into the spa to relax. Mewtwo and Shadow were in their human form and in the hot tub while Ash and Serena were on a couch watching them. Everything was quiet until Black and White walked in.

"Hey, guys! What's up?" Asked Ash.

"Same as you," said White, "We're here to relax. Who's that in the hot tub?"

"That's Mewtwo and Shadow," answered Serena. Black looked at them as they relaxed with their eyes closed.

"Huh. So they can turn into human form as well..."

"What do you mean, as well?"
