Pyroxian's a big fiery super-guy that my brother invented for the Marvel Super-heroes RPG (the original one, you know - with stats that were measured as Good, Incredible, Unearthly etc.). I was trying to think of a name that no-one else would ever use for my Hotmail account and tried Pyroxian and it worked, so consequently I've used it as my alias for all other messageboards ever since.
