Mecha Ridley does a lot more damage on 100% that plus the somewhere around 50% damage increase from Hard mode pretty much means only a couple hits will kill you.
It was clearly a case of spontaneous human combustion. I commend the people of Nintendo Ltd. for including many of life's real dangers as part of the Metroid series.
Seriously, Meta-Ridley does HUGE damage normally, compared to the other bosses on MZM, but on 100%, he does exactly 3 times more damage than normal, meaning he'll wipe out around 5-6 tanks by slashing you. Which basically means you're p'wned off 2 hits.
What game are we talking about here? Unless I didn't know ridley is called meta-ridley in mzm. Anyway, did you die when you got hit or just all of a sudden?
Edit: Never mind, I forgot about the final boss, which is meta-ridley. Dark SA-X is right, it does do uber damage in 100%

Not to mention that he has twice as much (or more) health in any 100% run...
Oh, I guess the MZM player's guide is wrong then, because it says robot ridley. But if it's definitely meta-ridley, then I'll just ignore what it says.
