yo soy...
If there's one thing you know you are, it's #1! You tend to be competitive by nature and love to show off your talents at every available moment, but that's often because you've put in a lot of practice to perfect your techniques and want to take pride in your effort. Because of this, you sometimes get a little too proud, fearing competing if you don't feel you can win and getting hotheaded if someone questions your capabilities. You hate losing.
Even though you may be a bit self-centered, you still care deeply for your friends and would stand up for them no matter what. You're deeply loyal to them, even if you may not always show it. Just because they're not as talented as you doesn't mean they're worthless, because you love them for who they are, although you may still joke around and give them a hard time — really, who doesn't like a laugh? You're incredibly brave and will be the first one to volunteer to venture off into the unknown or stand up against an enemy, perhaps letting your impulses get a hold of you before a rational plan is actually thought of.
While a lot of ponies may care how they look or concern themselves over what they're doing, you always want to present yourself in the coolest way possible. Whatever someone else is, your goal is to be 20% cooler. Fashion and style are a waste of time to you, because you know that's not what determines how cool a pony is. And if you think dying your hair all of the colors of the rainbow will make you 20% cooler, hey, guess what, because you don't care about appearances, it does.
So.. soy Dash. ¿sorpresa?
