Corn & Peg

• Corn (voiced by Jaiden Cannatelli in season 1, Niko Ceci in season 2, and Colin Critchley in the short) is a blue unicorn with a darker blue mane and tail, and wears a red jacket. He idolizes Captain Thunderhoof and has dedicated his life to doing good deeds for others along with his best friend, Peg. He used to be shy and scared of making friends until he met Peg at a bench while they were in preschool. He can use his horn if there is a need for light, or he can use it to pop or cut things. He can sometimes get goofy and clumsy and has kind of a big appetite, but he is still very loyal and often likes to encourage Peg by branding her as the best at everything that she does.
• Peg (voiced by Shechinah Mpumlwana) is a pink Pegasus with a golden-yellow mane and tail with flowers, and wears a turquoise dress. She's Corn's best friend and is rarely ever seen without him. Like Corn, she also idolizes Captain Thunderhoof and is dedicated to doing good deeds for others. Being a Pegasus, she is capable of flight, but because her wings are so tiny, she can't reach high altitudes and is limited to how much hang time she can have while airborne. She's also pretty strong for a foal her size. Peg loves to laugh at Corn's antics and fortunately doesn't get too annoyed by his goofiness.
• Captain Thunderhoof (voiced by Julie Sype) is a white alicorn with a sky blue mane and tail. She is a superhero who stars in a TV show and acts as a role model to both Corn and Peg. Most everyone in Galloping Grove is a huge fan of her. She is mostly summoned when Corn and Peg shine their horn and wings respectively, though they only call her when there is an emergency. Though powerful, her weakness is ice (which causes her superpowers to freeze).
