Yes that's right, interdpth and I actually took the time to find this baby and wow, that's a lovely debug menu. There doesn't seem to be any way of accessing it without a cheat code or ROM hack though. I advise y'all to mess around a little with it, here's an Action Replay code:
Arachnus dies in one hit from screw attack, and one charged shot from fully powered ice beam. It does to 4 diffusion missiles too.
Zazabi is wtf. Screw attack doesn't affect it, your beam doesn't affect it you have anything past charge turned on. Super/Ice/Diffusion/combination of those three don't affect it, only normal missiles.
Serris takes major damage from close-range ice beam shots lol. Diffusion missiles do major damage too. Not sure if it's possible to OHKO it... screw attack doesn't affect it.
BOX takes minimal damage from ice beam (unsurprisingly since ice beam only touches it for one frame).
Mega X isn't really affected by charged ice beam... it doesn't go through.
Nettori is destroyed by ice beam, since it's one of very few bosses that the plasma effect of the beam actually goes all the way through.
Basically, only boss so far slayed by screw attack was arachnus (i played up until nettori). Only bosses that the plasma effect destroys are arachnus and nettori so far.
