Probably the most benign inhabitant of Blackspace. The Postman is an enthusiastic and friendly ball of energy with a permanent grin on his face, who zips around Blackspace faster than anyone else, delivering letters. Or, he would, if his mail bag wasn't already full of letters to Sunny. As far as anyone knows, there's no one named Sunny in Blackspace. That's got the Postman pretty stumped! If anything, it seems Sunny is very loved. Why else would he have so many letters addressed to him?.
