Little Prince Corona is the spoiled and beloved colt of Celestia and an unnamed male unicorn. While plenty of ponies around the castle speculate as to his parentage, the Princess is keeping mum on who exactly Prince Corona's father is. He's a three year old bundle of energy, whims, and powerful bursts of alicorn magic. He's being taught the ways of mischief by both Uncle Discord and Cousin Lambent. Celestia doesn't care, and just hopes her little colt grows into a happy boy. He's been appointed as Heir to the Sun, and when he's a little older he'll get the training he needs to actually raise and lower the sun. But for now, his biggest challenge is sneaking cupcakes away from the kitchen without his mom knowing.

The youngest member of the next generation of Royal ponies, he is the third male and prince. His official title is Heir of the Sun.
