Just for curiosity's sake, why is Mystogan called Mistgun? :3 sounds weird to me.
I liked
Makarov - For being who he is. So old/perverted but wise and all. And the best part is him always keeping to the Fairy Tail tradition and keeping to his own believes. AND ALSO for treating all the members as his own children. Thats really a unique trait if you compare him to other Masters in their respective guilds ... :3
Ultear - For being my favorite all time female 'villain'. And because Time Arc Magic is too badass for one to simply ignore..
The rest in no particular order would probably be Mystogan, Jellal, Erza, Wendy & Gildarts.
BUT MY FAVORITE WILL ALWAYS BE EITHER LAXUS >
