Spines

Spines is the gender-swapped version of Spike, and as such, Dusk Shine's best friend and number-one assistant. As the only female in Dusk's circle of friends, she relishes the brief time spent playing with Pinkie Pie and Fluttershy. Spines is shown to have just as deep a crush on Elusive as Spike has on Rarity (thus harboring some jealousy toward the unicorn mare), but the thought of meeting her other self Spike does intrigue her a little. Like Rainbow Blitz, she occasionally refers to her friends as "brony".Comes from the fictional story; "On a Cross and Arrow"
