LSH symbols on the cartoon

-= Legion of Superheroes =- Cosmic Boy says, "Well. Let's see. Going by symbols... there's Tenz, and Dawnstar/Shikari, Polar Boy, Element Lad, Saturn Girl, the new Phantom Girl symbol, BLOK FOR CHRISSAKE, Triplicate Girl, umm-- I forget who that dotted lines one is, Lyle?-- I see Dreamy and Bouncing Boy, Cham, Ultra Boy, I forget that one, Shady, Brin, Val, I dunno the test tube-- Brainy, Cos, Ferro Lad, Colossal Boy, I forget who that one is but it's a girl..."

I'm a bad leader. I forget symbols. I suck. Who's the female-symbol with the horns and the triangle? And who's the test tube, Chemical King?
