Crimson "Valent" Azure
Rainbow is my girl even if she might be a [spoiler]lesbian[/spoiler]. The thing is, she changed over the course of the series. Originally in Sonic Rainboom she was in between Soarin and another male Wonderbolt which made us think she was straight. And yet there's plenty of tease between her and Pinkie/Fluttershy and her eventual mate (and I use the term loosely since it's open to interpretation) [spoiler]Applejack[/spoiler] but I think they wanted it that way because of Ashleigh Ball shipping the two.
