@Shane (SS2 Progress Updates thread that I could've posted in but didn't): as a boss, you'd be Nintendo Hard
Me, I think I'd have 1 or 2 phases. Bloom? 3. Dianke? Probably 2. Dark Serenity? 7 phases (!!!). Rita? I think one or two phases. Sycor? 4 total (two which I can't add). Eight bosses sharing the same HP? One phase. (Yeah, that's a plan. Run.)
Damn, I've had way too much free time. O_O
