Basic Trope: Violence occurs, but no blood or major wounds are shown.
Straight: Bob gets stabbed and falls down, but does not bleed or have visible wounds.
Exaggerated: Bob is shot five times from point blank range, then stabbed profusely, fed through a large meat grinder, and poked with a spatula. His dead body appears to be completely intact, with no blood to be seen.
Downplayed: A small amount of blood, looking more like a ketchup stain from a particularly sloppy lunch, shows where Bob was injured.
Bob is some sort of inhuman entity who has no blood, and so when he is shot, he does not bleed.
Bob is shot with an Agony Beam that does not cause physical damage to the tissue, but disintegrates the tissue to atom levels.
Bob was cut by a very hot weapon, so his wound was instantly cauterized.
