Note this ties heavily into Progenitors, so that's a recommended if not necessary extra read:
Life's Bounty
Pandora was in a hurry like no other.
She was used enough to her human form to set out much of the plates and silverware herself, cheating a little by letting her psychic power right the position of a bit of tableware occasionally, but the other people and Pokemon helping them out were essential in cooking and laying out the food.
Nevertheless, when they were done and Pandora sensed multiple presences near the door, she turned to them with a grim expression.
"I'm sorry, you all, but you must leave now."
A villager assisting her blinked. "Right after?"
A Machamp assisting crossed her bottom set of arms. We were going to get paid here!
At this Pandora extended a hand pulsating with psychic energy as the double helix symbol on her head between her pink bangs glowed. "As Kanto's Lady of Life I command you to leave! You shall all receive full compensation when I get the chance!"
Startled at the display, the workers all fled out of a side entrance, leaving Pandora to sigh and turn to the door of her temple.
"You can come in now, everyone."
The door burst open to reveal a young
platinum-blond man with rainbow highlights in a black and blue robe, accompanied by an entourage of people with hair as pink as Pandora's in a variety of physical ages, shapes, and sizes.
Pandora rushed forward and hugged the platinum-blond man then her fellow pink-haired individuals in quick succession. "Father, siblings, welcome!"
She moved back and closed the door with psychic power. "Now Farther, remember you can't assume your natural form here... You keep breaking through the ceiling!"
The young man rubbed the back of his head. "Well, got it."
Pandora smiled. "Other than that, enjoy the feast all you want. And the rest of you, feel free to be who you are!"
At that, with a cacophony of pops, the various assembled pink-haired people shifted to Mew, and started flying around, snatching bits of food from the table and gobbling them down. Pandora had assumed Mew form herself and smiled, before being embraced by two Mew with crystalline flowers hanging around their necks.
"Mithos, Collette, you're here!"
"Hi sis!" said Collete.
"Dad found out how to get us far away enough from our Trees to visit!" said Mithos.
"Oh, that's wonderful!" said Pandora, hugging them back.
She then noticed another Mew in glasses sulking in the corner, which she floated over to.
"Bartelby, are you all right?"
Bartelby hesitated before responding. "Not really."
Pandora frowned. "You're still upset about... Her, aren't you?"
"...Yes."
He diverted his attention to the feast, with the Mew plucking various items of food from their plates to eat and toss at each other.
"Why do we even do this every few hundred years? We're spirits of life incarnate, we don't even need food."
"Well, it certainly tastes good at least," said Pandora.
She looked over to the platinum blond young man gorging himself. "But everyone enjoys it - especially Father, he loves seeing all his children together in one place."
She smiled. "And... I do too. With how hectic life has gotten it's just nice for us to be a family."
Bartelby thought a bit and cracked a small smile.
"I guess I empathize with you there..."
Pandora floated in and gave him a hug.
Meanwhile, the platinum blond young man was about to bite into a large, ripe berry when Mithos gleefully snached it from him and soared up into the air.
"Hey! Mithos, you get back here this instant!"
His body stretched and glowed and changed into Xerneas, whose antlers gouged huge gashes in the ceiling as he tried to snatch the Berry back.
Everyone froze. Pandora stared aghast. Bartelby put his paws to his forehead in exasperation.
Xerneas simply chuckled nervously. "Um... I can fix that."
Happy Thanksgiving, everyone.
