Hm. I think I would be a daughter of Apollo who got the power of the sun fused into me, making me a fire bender, and who also fought demons in my spare time as a shadowhunter, and could snap out my wings when I felt like it, and went to Hogwarts during the schoolyear. Yep, that's right. I'm pretty freakin' awesome.
A shadowhunting wizard who can airbend and fly and is a daughter of Zeus so I go to Camp Half-Blood in the summer? No...? Are you sure there isn't a choose all button?
Umm... If I really had to choose I think I'd go with being a half-blood because I went to the real life CHB branch in Austin Texas last month and it was like the single most amazing week of my entire life
