Heart with a Lightning Bolt
Mystery Mint is a light blue Unicorn with magenta and cerise hair. Her eyes are almond-shaped (think Rarity), and also cerise colored. She is 17, like the Mane Six. Her Cutie Mark is a purple heart with a yellow lightning bolt inside it.
Mystery Mint is part of the Rockers group at Canterlot High. She is friends with Flash Sentry, Valhallen, Brawly Beats, Ringo, Crimson Napalm, and her best friend is Cherry Crash. Mystery likes to sing and will play guitar on occasion.
Mystery Mint is caring, calm, and quiet. She is very generous and loves to help others. She is comparatively softer than Cherry Crash, but that doesn't stop her from rockin' out!
Singing and Guitar
Mystery Mint has an amazing singing voice and she is the singer in her band, the Strike Hearts. She also plays the electric guitar, and is a pro at it.
The Strike Hearts
Mystery and Cherry Crash formed the Strike Hearts shortly after they found their Cutie Marks. Mystery plays guitar and sings, while Cherry Crash plays the drums. Mystery is constantly signing the Strike Hearts up to do gigs at Charity Auctions, a sign of her generous spirit.
Mystery Mint's Cutie Mark means two things: the heart represents the importance of teamwork, and the lightning bolt represents her skill with weather dioramas.
Mystery Mint can use her magic to make mini weather dioramas. For example, she often makes small, harmless, tornadoes during her shoes, less than a hoof tall.The weather makes her shows even more exciting and interesting.
Mystery Mint attended the Fall Formal. She wore a purple dress with a black studded belt. Her boots were various shades of purple, almost identical to her everyday boots. Mystery also wore 2 pink studded bracelets and a necklace with her cutie mark on her neck. She was hypnotized by Sunset Shimmer like everybody else. Later in the night, Mystery danced with Tennis Match and Fluttershy.
Battle of the Bands
Mystery watched smugly as Cherry Crash retorted, "Ha! You wish!" to Blueberry Cake the day the Dazzlings arrived. She and Cherry decided to band together with Thunderbass's band Thunderstruck for the Battle of the Bands. Unfortunately, they lost in the first round to Trixie and the Illusions.
