'''Basic Trope''': When a character is invisible, there will be some visual anomaly (that other characters ignore) to clue in the viewers as to that character's whereabouts.
* '''Straight''': Bob, an animated character, drinks the invisibility potion and becomes transparent, save for his outline. Alice doesn't seem to recognize Bob when he's in a room.
* '''Exaggerated''': Bob doesn't change at all, but is followed around by a giant arrow that says '''HE'S INVISIBLE NOW!''
* '''Downplayed''': Bob is completely invisible to the audience, although we can still see his footprints and a ''very faint'' shadow.
* '''Justified''':
** Due to an imperfection in the invisibility machine, Bob is fully invisible only from a certain angle.
** Bob becomes transparent, but with a different refractive index to the air around him. The "outline" is a stylized representation of the barely-visible distortion.
** Bob has turned transparent monochrome red. While humans can still see him, his foes only see in blue/green and thus can't.
* '''Inverted''': The characters can see Bob, but the viewers cannot.
* '''Subverted''':
** Bob's outline walks on screen, but it turns out that he just [[BreakingTheFourthWall painted himself "invisible"]] for the sake of a gag.
** Bob turns into an outline...then he fades entirely.
* '''Double Subverted''': ... but since he painted the pattern of a brick wall onto his skin, nobody can see him when he flattens himself against the wall.
* '''Parodied''':
** Bob drinks the invisibility potion and begins to glow. Alice pays no attention to this.
** Bob yells, "I'm invisible!" Despite the fact that nothing has changed, nobody can see him.
* '''Zig Zagged''': ???
* '''Averted''':
** There is no clue that Bob is invisible, except for his being ignored by other characters.
** Bob is invisible to the viewers as well as the characters, and the viewers aren't in on it until something gets lifted.
* '''Enforced''': "Do something about Bob. He's invisible, but that doesn't mean the viewers shouldn't see him."
* '''Lampshaded''': "Bob, [[PowerPerversionPotential get out of the ladies' room]]. [[GlamourFailure I can see your outline]]."
* '''Invoked''': "And this button turns my outline white and makes me transparent."
* '''Exploited''': A GenreSavvy Fourth Wall-breaking character makes a living tracking down invisible assassins, spies, and thieves.
* '''Defied''': "I knew that invisibility devices usually have some sort of visual cue that lets you spot them, so I tested this one carefully to make sure it didn't."
* '''Discussed''': "If I squint, and I know where I'm looking, I can see an outline."
* '''Conversed''': ???
* '''Implied''': After drinking a potion, Bob turns into an outline, and no one talks to him. He might be invisible, but everyone might just be ignoring him.
