Gravity. The ever-present force that many take for granted (and in some cases, they laugh at it). If ever a mineshaft beam falls or a building collapses, you can bet pancakes are in order, unless someone jumps in.
The Load-Bearing Hero - A moment when a character holds or lifts an otherwise heavy object from falling, to either save it or someone from being smashed.
When a poor guy is run over by a cart in Les Misérables (above), Jean Valjean jumps in with his strength that no one knew he had (thanks to his years in prison).
This trope is all too common in the superhero arena. To shake things up, they can lift heavy things to destroy stuff, as well as save, and anything is up for grabs.
Perhaps The Load-Bearing Hero can be a machine, holding up another machine (or a blast door).
Most importantly, a character doesn't have to have superhuman strength. It could be something as simple as keeping an entertainment center from falling on kids. I remember my father jumping out of bed during an earthquake to keep an armoire from falling on my mother. Massive hero points awarded that day.
Ever used The Load-Bearing Hero in your writing? Just a normal person, or did they have super powers?
I'm David, and this is REALLY heavy ...
