Disc Horse gets a full ref because turns out I love them.

Scorpion Sting, better known by their stage name, Disc Horse, is a famous DJ and a famous troublemaker. They love antagonizing ponies at their shows over controversial fictional topics and seeing how far they can push somebody before they snap. Some of their favorites to whip out are that Undertale wasn't well written, Steven Universe isn't actually that good, everyone in Overwatch is gay, and early Spongebob wasn't funny. If you've seen people write novel-length posts about a topic on tumblr, there's a good chance Disc is all over it and ready to spout some hot takes. They don't usually think the things they say are actually true, though— in fact most of the fandoms they start wars in are for media they don't know or care about. Either way, it's hilarious to watch ponies struggle to prove them wrong every time they open their mouth.

Disc is also a pixie (pygmy pegasus)— short, stocky, feathery, and lightweight. They'd be a pretty agile flier if they weren't so worried about ruining their meticulously styled hair. Also, because I've been watching a lot of Snapcube lately, I imagine they sound like Alfred Coleman, and are similarly pretty damn good at freestyle rapping. They've got a lot of lightning themed tattoos as well! They just think they're neat.
