This is for a good old buddy who's quite persistent! (Nah jk. I get ya bro. Sorrs fer being a little ignorant. Kinda procrastinated this ship heheheheh.)
NightmareXFredbear
Positives: I think I've heard of this ship once before. Quite an interesting one. I could definetley see why it appeals. I think it would be kinda cute to see the big black bear cuddle his smaller counterpart. D'aw. These two could have a bit of conflict, creating drama for a good storyline.
Negatives: 1. Nightmare isn't a physical character in my au. 2. Nightmare wouldn't care for that shtuff; he's too busy chasing down a poor kid. 3. My Fredbear be taken. (I ain't gonna say who just yet hehehehehehehehe.)
Overall, I think I quite like this.
