Something tells me Spike would be pretty excited to know that you'd be some kind of pony superhero. Just, be careful he doesn't try to make himself your sidekick.
You thinking it kind of has to be done at this point? It seems that apparently it's becoming a rite of passage into "bronyhood" to draw one's self as a pony. It's happened to me, but I need to get more used to using actual outlines, instead of shapes joined together. Anyways, Comet Blaze would have a cape and a mask; I'd just have glasses.
