Wild Fire

Wild Fire is a background Pegasus pony who first appears in Twilight Sparkle's flashback in A Canterlot Wedding - Part 1. She has a cream coat, dark brown mane, brown eyes, and a flaming tire cutie mark. She is an original character of Sabrina Alberghetti.

Description and design
Wild Fire is an original character —though drawn under contract— of Sabrina Alberghetti, one of the storyboard artists on the show who storyboarded parts of the season two finale. Her design is also used with different color schemes and cutie marks for "Wild Flower" and "Rainbow Drop". Wild Fire's cutie mark is the same as that of "Hot Wheels", a flaming tire. According to a journal by Sabrina Alberghetti, "Wild Flower" was originally Wild Fire. Before Tabitha St. Germain confirmed her role on Twitter, Wild Fire's voice actress was unknown.

Depiction in the series
Wild Fire first appears in A Canterlot Wedding - Part 1 during Twilight Sparkle's flashback, arguing with Lucky Clover. She calms down immediately after Princess Cadance casts a love spell on the argumentative couple.

She later appears in Wonderbolts Academy with the same design as Derpy and "Raindrops", in two shots: with "Milky Way" and "Pizzelle" in the first, and in place of "Wild Flower" behind Lightning Dust in the second.

Other depictions
Wild Fire appears on the Season two poster. In the IDW comics, she appears on page 17 flying while holding onto Lucky Clover, on  page 1 running with MandoPony, on  cover RI as a filly in a picture showing filly Fluttershy, on  cover A flying behind Princess Luna with many other characters, on  page 6 flying with Rainbow Dash, and on  page 17 as a filly in Shining Armor's flashback. In both of her first appearances in the two comic book series, she leaves a trail of dark smoke behind her while flying.
