I've always thought it would be interesting if the roles were reversed. This next one comes to us from Janus366.
The crowd of pokemon cheered with great excitement and expectation as they waited the start of the games on the massive coliseum. The stands where absolutely filled and packed with them due the promises of their Lord of fun, bloodshed and free food if they attended. Especially the latter, because free food and berries were always a good stimulus for any pokemon to go to see the games. Where this was just one of the many tactics Emperor Uxie used to keep his subjects both happy and content. All hail Emperor Uxie! Lord and sovereign of the mighty Pokemon Empire!
On the main stand, Emperor Uxie sit in all his glory on his throne. He was wearing a purple toga, an olive crown and was being dutifully served by his loyal Alakazam servants. One of them was fanning him with a long feathered fan. One on which their feathers looked suspiciously familiar...
After being informed, Emperor Uxie raised from his throne and finally proclaimed with a plain telepathic message to everyone present:
"Let the games begin."
The crowd cheered as one of the gates of the coliseum opened. After a brief moment, two human figures came out from it dressed with the garments of gladiators. Both were wearing mostly loincloths held by belts and sandals, but the older figure also had a shoulder and arm guard on his left arm. While the younger one had metal wrapping tied by thongs on his right arm, a greave on his left leg, wore a helmet which covered his head and also carried a large square shield with his left hand. The older gladiator was armed with a trident and a net, while the younger one carried a short sword.
"Where are we Sifu?" the young gladiator said to his master. "And why are we wearing and doing this? We should be travelling to LaRousse City with the others!"
"Don't worry Arthur" Batuo responded to reassure him. "The powers that be decided that today we are doing this. But after we finish our task, in no time we shall return to our proper time and place with no memory of this."
The two approached Uxie's stand and Batuo raised his trident.
"Hail, Emperor! Those who are about to die salute you!" Proclaimed.
Uxie just shrugged off the gesture.
"Just go and impress me..."
Then a second gate opened, and from it came out the three Legendary Beasts of Ho-Oh. Who different from their usual selves, were growling, roaring and snarling like actual beasts with no intelligence. Only hunger and violence seemed to cross their minds as the crowd exploded with excitement from the imminent fight.
The two gladiators faced their opponents.
"Arthur! Just remember your training and everything is going to be fine!" Said the old master.
"Right, Sifu! These savage beasts are no match for us!"
The two clapped their hands as they opened their chakras. With a shockwave emanating from their bodies, they were now covered in battle aura and ready for combat as they prepped their weapons.
"For Aura and the Guardian Monks! To battle!" proclaimed Batuo as the two charged the wild beasts.
Uxie just stood still on his throne as he quietly contemplated the carnage unfolding upon him.
"Yes...yes. How fascinating...rather impressive for humans."
Before rediscovering Aura Guardians, he had lost hope that humanity could impress him again. But after learning of what they were capable off, he then decided that maybe humanity could still prove to be interesting to keep around.
"At least Ho-Oh's beasts are still useful for something..." Uxie thought as he slightly observed the feathers of the fan above him. Feathers which had come from the tail of the previous Emperor before he had ousted him.
"The games are just beginning..." He said to himself pleased as one of the Legendary Beasts cried in pain and the crowd roared more excited than ever.
The gate from which the beasts had come was now closed. But from behind it, one could see the red eyes glowing in the dark of dozens of hungry Swalots, including one of giant proportions.
"And I can't wait for the final event..."
Behind the gate, the loud distinctive roar of a certain emerald dragon could be heard.
