Any other OCs you say.... it’s going to be hard to get the bios for some of these be here you go.
Ender the Yveltal: has super advanced senses, can fly extremely fast, and possesses psychic abilities like telekinesis.
Psychozard the Charizard: a charizard that once stopped Mars from crashing into the earth with only telekinesis. Her psychic abilities are insane and she can also communicate with people telepathically no matter where they are in the universe.
Electro the Eternatus: it’s dynamax cannon has vaporized holes through mountains miles wide. It’s said his dynamax cannon is nearly 5 to 10 times as powerful than a normal Eternatus’s dynamax cannon. It is speculated to be even more powerful than that. It also can control the flow of electricity.
Draceon the Jolteon: a Jolteon which is capable of using massive amounts of electricity and controlling its flow, it can also fly.
Neon the Scyther: a scyther who’s blades are the equivalent to a light saber and can cut through almost everything (except bedrock cause of Minecraft rules, this is also a joke)
Quantum the Lunala: a Lunala which can send anything to the shadow realm, she can also travel there and back. She can travel through space and time and even reach other dimensions without the use of portals. She is the daughter of Nebula.
Nebula the Necrozma: a Necrozma with almost unlimited abilities, able to learn and use any moves. It is also a god.
Vortex the Zamazenta: it’s shield is unbreakable (Electro’s dynamax cannon is an exception). It uses its steel wings to create huge gusts of wind while in battle.
Aura the Braixen (or you could go with the Fennekin form as well): a Braixen which is capable of freezing anything. It can live in extremely cold temperatures.
(Finding the bios for all of them is not going to be easy, for Psychozard, Electro, Aura, Neon, and Ender is going to be near impossible)
