Oy, I'm the worst at names.
As for the boss, though, my main question is how will it avoid those little ground spikes if it can't jump in ball form?
Maybe that'll make it too complex though.
A brief look at metroid bosses makes them appear to be semi-random-syllables of the form C(r)V(C). Using that pattern, you could come up with, I dunno, Nralik or something.
Sorry
