What the title says, folks.

I've been wondering about this for some time now. Reason being that Dark Falz Elder doesn't look like any of the other Darkers. Well, most of them anyway. There are a few, I know, that have the same stone-like appearance as Falzy; the shield guys and spinning top Darkers. All the rest appear insect-like.

So, what's the deal, guys? Why does Falz (and a few others) look so different from the Other Darkers? Are the stone Darkers just a different type of Darker? Are they not Darkers at all? I havn't done any story mode yet. Is the answer there maybe?

Actually, what are the Darkers anyway? Do we even know that yet?

Help!
