Ash Ketchum: Unleashed

Chapter 24- The Conflict of Centuries

The Legendaries were hesitant to attack the group for some reason.
'What is the matter with you? Go!' Tobias ordered, firmly.
And then he turned. Everyone turned. To look...
Portals began to open. At least over fifty opened, and from it stepped all the Legendary Pokémon whom Ash had helped, plus the Alolan and Galarian Legendaries.
'Chosen One, on your left.'
Mewtwo and Mew. Celebi. Lugia and Ho- oh. The Legendary Birds and Beasts. The Weather, Tao, Sun and Moon, Order and Creation Trios. The Tapus. Genesect. Heatran. Darkrai and Cresselia. Latios and Latias. Heatran. Eternatus. Arceus. Diancie. The Regis. Meloetta. Victini. The Lake Trio. Jirachi. Deoxys. Manaphy. Shaymin. The Four Musketeers. The Kami Trio. Spectrier and Glastrier. Calyrex. Zamazenta and Zacian.
All facing clones.
The fight began viciously. Soon, portals began to open and the Legendaries fell against each other in other different dimensions. The earth began to shake. The world was in trouble. The Legendaries were not holding back, so if they had not fought in different dimensions... the human race would have been wiped out.
Still, all across the world- there were earthquakes, volcanoes, tsunamis, floods and landslides... there were only three billion people.
Dead Legendaries lay on both sides, bodies falling through all sorts of different illusionary portals.
Everyone in the castle ran for cover, and luckily, no one was killed. At least, among close friends and confidants.
Rocks, dust and gravel collapsed through the chamber...
Everyone Ash looked for was in a very alive and conscious state. Ash heaved a sigh of relief.
Then, he saw the battlefield. Both original and clone Legendaries were dead, all of them... except Arceus and his clone.
And Arceus was knocked out.
'Well, Well. Come, then, where is your valor? Fight my Arceus, Ash.' Tobias taunted.
'Indeed, I will take you up on that.' Tobias was shocked, he had not expected that answer.
'Go, Charizard!'
