This character is a wild Honedge.

What is a Honedge? A Pokémon of course, though this one is a variation.

That's right, this character is a variant Pokémon found on Deviantart here:

All credit for this fakemon goes to the artist, who can be found here apparently;

Apparently this Pokémon is born when a departed spirit inhabits a sword. Honedge’s soul once belonged to a person who was killed a long time ago by the sword that makes up Honedge’s prison. The purple and gold eye on the sword’s handguard is the true body of Honedge. With its old cloth, it attaches itself to people and drinks their life force.
