So while surfing the internet I found out that Supergirl has (or had) a horse! Along with other animals, but that's irrelevant, because I wanted to draw the horse! His design is based off of one of Lauren Faust's sketches for a Foster's House horse: [link]
. And that's what I imagined Supergirl would say to Comet after they... fight crime or something. I have no idea. I'm not that much of a comic fan.
There's very little art of SBFF on dA. If you look up SBFF, it says there are about 150 deviations. But if you go through, several are journals, some pictures are completely irrelevant, and a lot are... ahem... low quality. The actual words "Super Best Friends Forever" have over a thousand results, but between some really great pictures at the beginning of the results, there are a lot of other things, pictures of people with their friends, and tons of other things.
Also, why does Supergirl's logo have to be over her boobs? It makes it twice as hard to draw!
It's way more creepy if you know that the horse had a crush on her and turned into a human at one point and tried to get laid.
