Shadow!!!

Shadow is the representation of forgotten ideas and complications. It hates creators and authors and wants all of fiction to burn. This is Its mission. This being is beyond the concept of "canon".
== Bio ==
Not much is known about the creation of this being. It is not from the undertale omniverse and doesn't have a physical form. It has fictional awareness and is beyond most concepts. Its creation is left as a mystery but we do know that it can appear as whoever it wants. It hates creators and gets its hatred in check by killing avatars. It knows that they can't die permanently but it forces the creator to have to revive them over and over again. Its power exceeds far beyond the power of most fictional entities. It doesn't feel emotions but hatred is simply the only emotion that the human mind can understand when trying to comprehend this entity. It is some sort of eldritch abomination. Its name can't actually be spoke via a human tongue so shadow is the closest we can get to pronouncing its self proclaimed name.
== Profile ==
=== Null Realm ===
It's realm is an infinite void of empty nothingness that could drive anything mad and insane. It looks different to every person who sees it because every has their own interpretation of it based on how much their brain can comprehend. But no one has ever truly been able to comprehend its actual appearance besides It. 
=== Appearance ===
It doesn't have a physical appearance or size of any kind. It is beyond that sort of concept. It can appear as whoever or whatever it wants. To mock creators it does like to appear as its own avatar of sorts. A black skeleton that is melting with dark red sockets and a glitchy brown robe. It also loves to appear as K. 
=== Personality ===
It doesn't have a personality because it is beyond our concept of personality. From what we can comprehend, it is a horrible creature. It loves chaos and destruction, or at least that is the closest we can comprehend when handling its actions.

He has so many abilities that I can't possibly write them all down but here is a fraction of the amount of abilities it has.

Omni presence
Infinite power
Infinite skill
Infinite potential
Infinite code

As I said, this is only a fraction of the amount of abilities it has but hopefully this gave you an idea of how powerful it is.

A pathetic weakling who has no idea about what power truly is.
