Pokémon: The Poison King Plays with Fire

【Pokémon/Pokémon/Elves/Pokémon/Pokémon】
Urban elf/dark (starting from the middle and late stages).
Ye Kai accidentally traveled to the world of urban elves.
He discovered that this was a world that divided the elves into different levels.
Poison-type Pokémon are extremely poisonous, and people avoid them!
His starting sprite is a shiny gas egg.
There is no Poison King in this world yet.
Maybe I can fill this gap?
[Ding! The host has detected the intention to fight with poison-type Pokémon!]
[The Poison King system has been generated! ]
Many years later, Ye Kai, who had become the king of poison, went one step further and became the champion of the World League.
This is a cruel world. The Alliance controls less than 70% of the planet, and natural disasters are rampant!
Dark Elf, Red Eyes Boss, Overlord, Gigantamax, Mega Evolution, Star Crystalization...
Everything you know and don’t know will come to you.
What mysteries are hidden behind the alliance, and how terrifyingly powerful are the mythical beasts?
Subvert your understanding of Pokémon, and a terrible reality awaits you.
