I agree, kind of had that problem with my earlier usernames. This one feels more "me" (though my previous name felt better at the time I got it changed) and it is also related to Pokemon while my earlier usernames weren't.
Something from Zelda? That's cool. Either way, you'll have some time to think about it as name changes won't happen again until April
Understandable. Coming up with good usernames for forums is pretty hard if you ask me. Personally, I think it should be something that is meaningful to yourself but not in a stupid or embarassing way. Not to mention, it should be a name you are comfortable with using. That's how I feel, at least.
