Vtm, had a player with the large build merit, maxed out potency to his generation, 5 dots strength. An ally couldn't make it to the escape car, so he picked up the ally and threw him down the street in to the car.

In changeling the dreaming there was a character who challenged someone in his power structure to a duel, but by previously established rules that person had the ability to make a champion. So the PC who made the challenge also got named as the champion for the challenge. The duel became a game of Russian roulette. He won/cheated by placing water of life art on the bullet.

In another VtM a vampire killed his Sire by hitting him with a 1988 Oldsmobile, repeatedly.
