Pokemon: Red's Death

Legendaries, Mythicals, Primal and Mega

Hoopa got angry seeing all of it's enemies and transformed into it's Unbound form! Now it was almost unstoppable! It did what his trainer, Green, had told him to do and started summoning all the legendary and mythical pokemons of the Pokemon world. He broadened his portals and let all of them come into the battlefield through them! All of them were ready for it since they knew it was for the sake of the Pokemon world. Hoopa only summoned them for help in the time of crisis, after all. And they knew that when he is summoning 'em ALL, something BIG is going on! So they HAD to give it their all! 

Articuno, Zapdos, Moltres, Mewtwo, Mew, Raikou, Entei, Suicune, Celebi, Regirock, Regice, Registeel, Latias, Latios, Kyogre, Groudon, Rayquaza, Jirachi, Uxie, Mesprit, Azelf, Dialga, Palkia, Giratina, Heatran, Darkrai, Cresselia, Manaphy, Shaymin, Victini, Cobalion, Terrakion, Virizion, Keldeo, Tornadus, Thundurus, Landorus, Reshiram, Zekrom, 5 Genesects, including the shiny red one, Kyurem, Meloetta, Xerneas, Yveltal, Zygarde 10% form, Diancie, Volcanion, Type: Null, Silvally, The Guardians of Alola; Tapu Koko, Tapu Lele, Tapu Bulu, Tapu Fini... Magearna, Marshadow, Zeraora, Meltan, Melmetal, Zacian, Zamazenta- ALL OF THEM HAD BEEN SUMMONED BY HOOPA! 

Before Hoopa could summon even more pokemons Deoxys used it's psychic powers and broke Hoopa's rings, which closed down the portals. That made Hoopa rage and him used Dark Pulse on Deoxys but it quickly transformed into it's defense form and then used Protect and then Toxic on Hoopa! That slowly started hurting Hoopa. 

Pegagod was afraid that Hoopa would cause even more trouble for them so it finished him off with the fairy type MEGAHORN which did 170 damage on Hoopa and finished him off for the good of the alien pokemons.

At this point, Lugia had told every other legendary and mythical pokemon that this time, they were fighting for the sake of the Pokemon world... And this time- IT WAS THEIR BIGGEST FIGHT YET! THEY HAD TO GIVE IT THEIR ALL! The alien pokemons posed an even bigger threat than Team Empire. They were even a bigger threat than Dark Arceus, which had world destructing powers! 

And the legendary pokemons truly wanted to give it their all. So one by one... All of them started coming to their true potential... 

Articuno, Zapdos and Moltres reversed into their PRIMAL FORMS! 

Articuno now had wings completely made out of ice... Zapdos' entire body was surrounded with electricity! And Moltres' entire body was completely made out of fire. Their speed, defense and special attack had been boosted sharply! Now, the trio could show the world their TRUE POTENTIAL and the power that they once possessed!

Mewtwo and Rayquaza MEGA EVOLVED!

Mew also Mega Evolved! Mew had an insanely higher special attack and special defense now and it also had the ability of psychic barrier, which put up an unbreakable barrier around Mew for the first 2 turns. It also had a longer tail and DNA surrounding it.

Lugia and Ho-oh also reversed into their Primal Forms!

People were being surprised at how all these pokemons were primal reversing and mega evolving. They had never known that these pokemons could do that in the first place! What was happening was beyond their imagination.
