Pokémon, Inkaros, my starter Pokémon

Shidou travels to the Pokémon world and inherits a fighting gym.
He intended to summon a powerful Fighting-type Pokémon to overpower the Elite Four and kick the Champion, but unexpectedly, the system linked to an unknown dimension...
When the light from the first summoning faded, what appeared was not a rare bear apprentice, but a small mantis with a bright green body and sharp arm blades.

As Arceus, the creator god, prepared to destroy the Pokémon world, he descended with the power of the eighteen stone tablets. A golden figure streaked across the sky, blocking the aura of the world-destroying [Pumice Stone].
Arceus: "Hmm? An unknown Pokémon? Fearless ants, the stone slabs are all open, all is nothingness under the law! Hmm... wait? What the heck is this Light-attribute attack called [Celestial River Holy Light Slash]? The stone slabs don't have any related attributes!!!"
Is this...right?
Shi Dou: "I've already said, this is my family's Light Mantis. It only kills divine beasts, not nobodies!"
