So I've seen a few screenshots of Echo today but ever since I saw her on the poster, I've had a little theory; I think Echo may be based on the Greek Myth of Echo and Narcissus; of course I can't confirm this until I get to see her backstory but I just feel like the name Echo and that it's a Water Skylander match up well to the Myth. (I'd post a link but the Wikipedia page has artwork with nudity so I won't ;v

As far as I can tell, Echo attacks with songs/music although the original Echo was Cursed to only repeat what has been said to her (which is why she was named Echo.)
I'm just wondering if anybody has any thoughts on this and maybe wether anybody thinks some Skylanders has an origin outside the Skylanders universe, such as Lightning Rod obviously being a lot like the Greek god Zeus.
