Character/Pairing/Set/Etc: (Pick the one that applies to you.)
Note that you don't have to pick a pairing; it can be a character or something else altogether. Since this idea sprung from Fullmetal Alchemist, to use that as an example, you can pick a character, such as Edward Elric; a pairing, such as Elricest; a group, such as the Homunculi, or even something abstract, such as Touka Koukan.
Also, make sure you provide full names and series names, not abbreviations.
