Celebi fought hard on the matter, but finally got Arceus and Dialga to agree. The future was a terrible place with the two factions of Red and Green still at war. They had been this way for decades with no hero rising to the challenge to stop them. Might even be that one wasn't born yet and wouldn't be for quite some time. They couldn't wait or there wouldn't be a world for future heroes to be born into. They needed a hero to calm the fighting and Celebi knew the perfect ones for the job.

"Celebi! What are you doing here?" Mew asked her friend, as she appeared before her at the Tree of Beginning.

"You know what I'm here for." Celebi answered as she glanced to the crystalized figure at rest in the heart of the tree.

"It can't be!" Mew exclaimed.

"Yes, he is the only one. Arceus has agreed and so has Dialga. I need a favour from you, though." Celebi requested.

"What?" Mew inquired.

"I need you to sneak into the castle and retrieve the staff of Sir Aaron. He needs Lucario."

"That's all? That's easy! Sure, I'll do it in no time! Back in a flash!" Mew giggled as she teleported out.

Celebi sighed. Her friend always had so much energy and seemed too childish, despite her position of the holder of all genes in the world. Still, Mew would get the staff no problem. She could walk in and take it if she wanted to or teleport out. Celebi looked to the second trapped person she needed. She needed to revive him. Her own temporal powers would allow that, as she would increase the time surrounding him to strengthen the dormant aura inside him until it burst. Thus, she hoped, it would bring him back to full life. She closed her eyes and lifted her arms, surrounding him in a temporal bubble.

Celebi honestly hoped this would work.

Mew teleported into the castle and floated up toward the light fixture. Now all she needed to do was find Sir Aaron's staff, without getting caught. Seemed easy enough. Mew searched the room she was in and saw nothing.

If she were the queen, where would she put a staff of the aura guardian who gave his life in an attempt to quell the fighting between the two sides? This would be very important and she would want everyone to see it… the main hall which happen to be the throne room!

Mew teleported in and saw no one there. She smiled as this was perfect. She just grabbed the staff and popped out. She then floated down and picked the staff up with Psychic. As she went to turn around and leave, she heard the door.

"Oh my!"

Mew fully turned around and saw the queen standing there. The blonde ruler had her hand over her mouth in shock. From what Mew wasn't sure. It could be the mystical Pokémon floating in the hall or the fact said Pokémon was attempting to steal a treasure of the kingdom.

"Please listen, Your Majesty!" Mew said quickly. "We are trying to revive Sir Aaron, so he may once again try and stop the fighting. No one else but him can do this. We have no time to wait or lose. If we are successful in reviving him, he will need his staff and more importantly… Lucario, who lies trapped inside."

"Are you saying Lucario is in there and this madness can end?"

"Yes."

"I would very much like to see peace, Mew. Please then, take the staff and return our guardian to us, so he may once again try and stop this war."

"Thank you." Mew said, as she bowed to the queen before flying off with the staff trailing behind her.

As she left, the queen kneeled down in front of the painting of Sir Aaron that was finished not that long ago and clasped her hands together. She prayed to Arceus that they would successful and she would be able to see the world at peace.

An audible humming resonated deep within the Tree of Beginning and the light from the build up of Sir Aaron's aura was almost blinding to look at. Celebi was beginning to struggle to contain the ever-increasing volume of aura inside her bubble and relief flooded through her when her friend finally reappeared. Her eyes fell upon the sceptre clasped in Mew's paws. "You got it!"

"Of course!" Mew pouted, looking almost offended. "Did you really think I'd fail?"

Celebi ignored her comment as she grit her teeth and stared deep into the temporal bubble and its writhing blue contents. Taking deep breathes, she closed her eyes and focused on Sir Aaron's aura. Bringing a human back from the dead was nearly impossible, even for a Legendary. Bringing back a human who'd had his life force torn from his body was impossible. But there was just one thing they could try…

She learned the feel of Sir Aaron's aura. She learned its movements, its colour, its intensity. And then, she opened her eyes, searching across time and space for one who's aura matched his.

It would be impossible to fully resurrect Sir Aaron, but if she could find somebody with a similar aura, there was a chance that she could place Aaron's spirit within their body to reincarnate him. It may not have been perfect, but it was their only chance.

Thousands of lives flashed before her. Eras swept by in a blur, lifetimes cycled from birth to death as she scanned the world to no avail. For a minute, despair begin to well in her chest as she watched auras of all kinds flicker before her eyes, none of which matched the one the world so desperately needed.

And then she found it.

"What is it?" Mew perked up, floating to Celebi's side. "Have you found a matching aura?"

"I have." Celebi responded, numb to the temporal bubble that was threatening to burst at any second. "A perfect match lives."

"That's amazing!" Mew exclaimed, not appearing to notice Celebi's sombre expression.

"He lives four hundred years in the future."

The excited grin melted off Mew's face. Quietly, hopefully, she said: "But… It's all we've got, isn't it?"

Celebi began to nod when the bubble contorted and she grunted, struggling to contain the energy inside. Raising both her hands, she concentrated all her energy on the ball of aura before her and it slowly began to contract. The aura protested, threatening to explode outward as it condensed.

Then, sweat trickling down her body, she pictured the time period in which the hero was to arise in. She pictured his home, his mother's face as he was brought into the world. She pictured the aura that was so similar to that of Sir Aaron's dancing through his body and she pushed the bubble she had created through the stream of time towards him. The aura surrounded him and Celebi let out a breath she wasn't aware she'd been holding as she watched the unborn baby's own body accept it.

It took everything in her power not to slump to the floor right then and there. Mew tentatively approached her, still holding onto the staff she had retrieved. Without a word, Celebi tapped into the excess aura that was still hovering in the air to free the trapped Lucario inside. She could hear him begin to say something when Mew floated down and touched a paw to his forehead, knocking him out.

Celebi held a weary hand over Lucario's body. Lucario's form shifted to that of a Riolu, before curling and hardening into a blue egg. Then, with what little energy she had left, she sent the egg down the same path as she had Sir Aaron's aura.

She slumped to the ground, deaf to Mew's cry of surprise. It had been done. The future lay in his hands now.

The sky rained fire and a wave of aura burst from his body when Ash Ketchum was born.

Things would change.
