WoodenToaster and Glaze are two pseudonyms used by a British brony musician. He prefers to be called Glaze, but is more widely-known by his YouTube account name WoodenToaster, which started out as a random video game handle and has no particular pony or music connection. His OC pony is female because he dislikes the stallions' blocky design
