Scrollos is indeed one of those characters, that most Europeans are propably aware of. Much like that ghastly UK-drawn Horde Prime.
Personally I have never read or even heard of a story where they would reveal his face completely, or tell more about him as a character...
The couple images I could find, show the basic view of him from behind.
There is one image that shows him facing to the audience.
His colour-scheme differs, so you can all make up your own version.
