In relation to my future-timeline fan-fiction, Flight of the Valkyrie (circa The Last Problem), this would be the appearance of Tempest Shadow, AKA Fizzlepop Berrytwist. After the fall of the Storm King, she journeyed the world to find herself, earning her cutie mark along the way. Despite encouragement from others, she did not want her horn repaired or replaced, having learned to accept who she is for what she is, thanks to the Mane Six. She spent some time as a motivational speaker along her way, now coming full circle back to Equestria and Canterlot.
