My take on missingno

A long time ago one day Arceus was making the Pokémon world a small entity came into his world and told him story's about the world and how adding humans was a mistake and the Pokémon should live in harmony not let other take them for granted.

But Arceus would not hear his word instead banishing him to a void where the entity's body would began to fall in on its self and glitch turning it into A beast who no longer cared about the world and anything it fused its body with millions of Pokémon to create a vessel and broke out of the void hellbent on destroying everything it no longer cared.

Its first form (as seen in Red and Blue is it's first attempt at a vessel) But over time as more off the Pokémon world was shown to it, It began to fuse more and more into its vessel From Red and Blue to Diamond and Pearl it gained knowledge and learned of the worlds secrets and sins so it now is only growing stronger and when it reaches its full power.... Humans, Pokémon, The Universe... will be gone...

it's only a matter of time...
