Sugarcoat

Sugarcoat is a female human and one of the Crystal Prep Academy Shadowbolts in My Little Pony Equestria Girls: Friendship Games, and a rival to the main heroes in Friendship Games and Dance Magic.

Equestria Girls: Friendship Games
Sugarcoat appears in Friendship Games as a student of Crystal Prep Academy and a member of its sports team, the Shadowbolts. She first appears on the bus to Canterlot High School after Twilight Sparkle gives a clumsy speech to her teammates. When Twilight sits down next to her, Sugarcoat bluntly remarks on the ineffectiveness of her speech.

Sugarcoat participates in the Academic Decathlon of the Friendship Games, being paired with Indigo Zap during the woodshop portion. They construct a two-story birdhouse that wins the event, and she gloats over her victory to Sandalwood and Micro Chips. During the spelling bee event, she misspells the word "cymotrichous."

In the Tri-Cross Relay, Sugarcoat is again paired with Indigo Zap in motocross against Rainbow Dash and Sunset Shimmer. When Twilight is unable to score a bull's-eye in archery, Sugarcoat comments that she is "really bad at this." She ends up failing the motocross event after being attacked by the giant plant monster.

During the final event, Sugarcoat joins Principal Cinch and the other Shadowbolts in pressuring Twilight into releasing the magic she collected throughout the Games, and she watches in horror as the magic transforms Twilight into the monstrous Midnight Sparkle. As Midnight slowly destroys the world around her, Sugarcoat and her teammates help save their fellow students and the Wondercolts.

After Twilight returns to normal, Sugarcoat is outspoken about the negative consequences of Cinch's actions, with Pinkie Pie remarking that it's "a lot to take in when you say it all at once."

Equestria Girls: Dance Magic
In the half-hour special Dance Magic, Sugarcoat appears with Lemon Zest, Sour Sweet, and Sunny Flare competing with the Rainbooms in a music video contest.

Personality
Sugarcoat displays an overly blunt, cynical attitude towards others, Twilight Sparkle in particular, pointing out their faults without hesitation. This notably contrasts with her name, which means to make something sound more pleasant than it is. Like most of her schoolmates, Sugarcoat is highly competitive, arrogant, and a poor sport. She is also willing to go to any means necessary to level the playing field, such as pressuring Twilight into using magic to their school's advantage when they suspect Canterlot High School of doing the same. However, she shows a more compassionate side when she comes to her rivals' rescue after her team's actions end up putting both schools in danger. In Twilight's Sparkly Sleepover Surprise, Sugarcoat shares Fluttershy's fondness for animals.

Role in the series
Though she doesn't appear much in the series, her Earth pony counterpart appears in Speedster's Marathon, where she helps her friend Indigo Zap follow in her father's footsteps as a Shadowbolt (Black ops division of the Wonderbolts developed by Luna), and later helps her save Rainbow Dash from The Speed King by helping Indigo steal his Shoes of Hermes to give Rainbow a winning advantage.
