Scraggly's spoiled older brother. After Scraggly was kicked out, he was pampered beyond all knowledge. One day his parents disappeared though, and only he knows why. He dares never to speak of it. He was adopted by many parents, all of whom were never pampering him as much as his true parents.
Because of said pampering, he thought of himself higher than a pony, and hated being treated any way else. Once his last parents didn't pamper him, he had it. He ran away from that home, which was ironically in Ponyville. He ran into the Everfree forest, building his own shelter, making his own food, and thriving. It's how he got his cutie mark...Thriving on the land alone. Since he ran away, he found himself too great to speak to any other pony.
scares him. Horribly.
Also, LoneHeart is now a colt.
It also seems as though he has made one friend, Heartbeat
. Of course he doesn't admit it.
