SWATLLAMA, whenever I see your username, I think of Gwonam from those awesome Zelda cd-i games saying: "Squadala! We are off!"
So I think to myself..."Swatllama! We are off!"
Anyway, Duckaiser came from DUCK and ALKAISER. Ducks being the bird, and Alkaiser being the superhero alias of Red from SaGa Frontier. He's not even my favorite character from that game or anything, I just think Alkaiser sounds cool, and I grew up with "henshin" shows like Sailor Moon and Power Rangers, so naturally I'd like that kind of thing. It's a name I came up with a long time ago, and maybe I'd prefer a different one, but I got used to it. And hey, I came up with it myself. There are so many things about yourself that you have no choice of, so it is somewhat satisfying to come up with another name for yourself. And that's one thing I like about having avatars on forums...I didn't get to pick my own face, but on the internet, I can look like whatever I want.
Sorry to ramble.
