Or how about there just are a small number of pegasus and perhaps unicorn crystal ponies? Pony race is genetic, it could just be extremely rare in their gene pool - rare enough that a crystal pegasus stallion would have a bright career as a royal bodyguard, being one of the few who could keep up with an alicorn.
that the Crystal Heart can give even non-crystal ponies a crystal form. Perhaps he’s just another regular pegasus but the crystal armor he’s wearing is channeling the power of the Crystal Heart even from this distance, granting him a crystal form and whatever benefits that gives.
Welp, that just about does it for me. Come get me when the Queen Chrysilombrarainbowshpie attacks the Crystestria and tries to usurp King Discordilunestia’s throne through a paper straw.
Must be hell when a dragon flies by
Best explanation thus far.
Thank Celestia, I’m not the only person whose primary reaction to this scene was that same question.
Okay, thanks for the clarification. It’s been a while.
Doesn’t explain the pic at all sadly.
Crystal ponies were glowy even without the Heart as long as they weren’t terrified by Sombra
