My favorite is Artemis. Not because shes the God of hunting because I'm not a huge fan of hunting. I just figure that she was/is a tomboy kind of person. Which is similar to me. Also, I just think shes freaking awesome! (Although her twin, Apollo, is pretty sweet to).
Hmm... This is a tough one... probably Zephyrus. I don't know why, I just stumbled upon him on the internet, and I really liked the way he sounded. Evidently, he's the God of the West Wind, and he loves nature. He's also gentle and kind, which I think is sweet. :D By the way, nice topic, this should be fun. XD
Athena, just because she was the goddess of so much. Wisdom, military victory (which included good tactics and skilled strategizing, not just skilled fighting, which is what Apollo was the god of), crafts, cooking. She was also the first teacher of the science of numbers. Plus, she was actually a kind and modest god, unlike the other Olympians.
