Was once part of a secret elite of Guardians from an Island not shown any maps, kicked out due to his height and contact with a strange hedgehog from another world. Badly hurt from some of the other Elite Guardians, who chipped his horn, crackings in his armor, and half helmet. Now hiding in the little shadows alone and sad, in a place called Equestria. His powers of exceeding speeds past 7599 MPH, was one reason he was once in the Elite, his power of being able to explode things, and help living things hover and speed up. Hiding in the shadows, finding that there was one like him, but not related, a Pony that can go 7600 MPH, wanting to introduce himself, but scared he might hurt her, he lost some control over his exploding powers due to the chipped part of his horn and cracks. Dreaming one day he may be able to gain control over his power again so he can finally get some new friends, besides that one hedgehog that he can no longer contact. His crush on Rainbow Dash eventually lead to fear all over Equestria...

(this will probably become a game, switching between the Ponies and FieryCrystal, with the group, Twilight Sparkle, Applejack, Rainbow Dash, Rarity, Pinkie Pie, Fluttershy, and Spike all set off to find FieryCrystal to uncover some mystery, the backstory of him, and why he attacked)
