While he started as a one-shot RP character design with a friend, this particular pegasus soon took on a separate life and character of his own.

Dainty Bolt is basically the equivalent of The Flash, capable of moving at speeds that make Rainbow Dash or any other pegasus seem like they're standing still, wreathed in green energy the whole while when he does it. However, he's a refugee from the land of comic books, having ended up in the 'real world' of Equestria through means unknown.

The difference between 'comic' ponies and 'real' ponies makes this extremely awkward.

So confused and out of his element around the real ponies, he quickly found a 'disguise' by working as a courier, with a record of very quick deliveries that somehow manage to not look too suspicious. No one knows his secret, but it's only a matter of time till he's outed.

But I'm sure the Equestrians will treat the superhero just fine.
