I'm boring. I named Red XIII Nanaki and everyone else Black I (Barret), Blue II (Cloud), Pink III (Aeris), etc....

I usually chose character names from movies of stories I'd seen or read. My recent favorite is naming a red dragon 'Dolarhyde', the title character of, what else-'Red Dragon'.

I had a college roomate who named all his female characters 'Babe1' and 'Babe2' etc....
