You know what you don't see very often? Long stories (by "long" I mean at least 100K words) that have G4 Tirek, and only G4 Tirek, as the main villain. Why is that? Has anyone ever seen and/or written a story like that? If so, then could you please tell me? Erm, except for The Legend of Sunset Shimmer: Ocarina of Time. I already know about that story, though I've yet to actually read it.

Probably because there isn't a lot of seen potential for making Tirek the primary antagonist. Though, there are a few interesting stories where he's (technically) the man character.

He has only one in cannon gimmick, and that limits the potential stories you can tell with him.
