Hi dylanblok,
I'm not quite familiar enough with the accelerated dragon to offer much good advice on what defenses to 1. e4 would be similar to it. That said, I'm going to offer a bit of advise on this subject, which you can take or leave.
Based on your post, I'm guessing that you've just started playing the dragon, and you want it to be your main defense to 1. e4. My advice is, don't start shopping around for another defense to 1. e4 just yet. I would advice playing purely the dragon for a while until you get really familiar with it. The more people you play, the more positions you will see, and the more you will know about it. Maybe get a second book on it to see what other authors say about it. Look in online game databases to find games where masters play the accelerated dragon. Maybe you can find a modern master who plays the accelerated dragon regularly. Pretty soon, you will start to be somewhat of an expert on the accelerated dragon, and you will be comfortable playing it against anyone.
Don't worry about being too predictable. This is amateur chess, not super GM level. Your opponents are probably not going to stay up late the night before they play you in order to find refutations to your favorite dragon lines. Besides, if a defense is half-way decent (which the accelerated dragon is), it will work even if your opponent is expecting it. It doesn't do you any good to try and learn two defenses at once, so I would wait until I had really gotten comfortable with the dragon before I started to learn something else.
Also, don't lose too much sleep over opening theory. At our level, opening theory is not half as important as one might think. People depart from theory so quickly.
Currently, I am learning the (hyper-) Accelerated Dragon for black, out of Chess Openings for Black, Explained. (Great book, by the way). I was wondering if there were any "off-beat" (or not) openings vs. 1.e4 that would be easy to fit into an Accelerated Dragon repertoire mindset. If not, is there an opening vs. e4 that is easy to learn and does not require learning tons of other lines, if white doesn't play what you want? (e.g. not the Latvian...would have to learn: what if white does 2.Nc3 instead, or 2.f4...etc. Basically, I want a "1..." move for black to use occasionally for surprise...or dramatic effect.)
Thank You
