{{Krid}}: The focus on this isn't on people being fine until they die, it's about how when they die spectacularly from unspectacular reasons despite being perfectly fine a moment ago. For example, a StaffChick landing the killing blow on the BigBad, causing them to paint the walls with their own blood.
LooneyToons: Would this be the character equivalent of EveryCarIsAPinto?
{{Krid}}: Kind of a cross between that and a localized LoadBearingBoss. What makes it distinct is that people involved seem to be held together more by their own life force than anything tangible, as the act of dying instantly makes them as durable as a wet tissue paper.
{{Ununnilium}}: So, it's basically "The only HitPoint that matters is the last".
{{YYZ}}: Right. You can still be up and walking around as long as you have even one unit left on your life meter - but when you lose that one, it's always in a spectacular manner. Megaman's just fine until he loses his last HitPoint - then he explodes. The ResidentEvil characters walk around just fine until they finally lose all their HP - at which point they collapse and die (''RE4'' was a step forward in that it was a bit more obvious about showing the effects of attacks on Leon).
Incidentally, where'd the name for this page come from? If it's a Douglas Adams reference, there's a mistake - the term he invented was SpontaneousMassiveExistenceFailure.
MorganWick: Wait, is this a conflation of two tropes? Because it seems to me that "you're perfectly fine until your last hit point goes" and "when you die, it's always in a blaze of glory" are two separate tropes, though it's true that the latter is a lot sillier in conjunction with the former. Call me a splitter...
{{YYZ}}: Well, given the fact that so many videogames include ''both'' of those ideas, I would say they add up to a single trope: "You show no signs of damage until you lose the last of your health, ''at which point'' you explode or otherwise die spectacularly."
{{Krid}}: I picked the name because it's descriptive, it sounds good, and it's not too long, although there was quite a bit of influence from roleplaying games like D&D and MechWarrior.
I agree with MorganWick. --DocumentN
Error: I removed the Dystopia reference, because the head flying off only happens when the head hitbox takes the killing blow.
{{A Guy}}: I'm marking this down as an AcceptableBreakFromReality.
{{Willbyr}}: Finished the rough sort of the entries; I'll leave it to someone who knows more about these games to sort the video games into their respective subcategories.
