Bare-Handed Truck Stop

You've Seen It a Million Times -- it's the classic way to handle The Reveal that a character possesses Super Strength. They stop a speeding vehicle by simply putting out their hands and halting it. Sometimes the momentum isn't entirely stopped cold, and they get pushed back a short distance, maybe even tearing up the pavement with their feet in the process.

Contrast Trainstopping, which is less a reveal and more a rite of passage.
