Someone's face, or whole body, is kept in shadows until just the right moment to come out and show his/her face to the other characters and/or the audience.
This person might be someone the audience knows, or looks like that person, or it might just be someone we don't know, but it's time to see who this character looks like.
The duration of the shadow hiding can also vary. It could be just a few seconds, to spending several episodes not seeing this person.
And how much shadow there is can also vary. This can range from going into the only source of light in a dark area, to leaving the only shadow in a bright area.
Occasionally comically subverted by having someone cluelessly turn on the lights to reveal the darkness-shrouded figure.
Contrast The Unreveal.
- In the first two issues of The Batman Adventures, the Penguin and Catwoman receive two-way video screens that put them in contact with a figure hidden in the shadows... until a hapless henchman turns on the lights to reveal the Joker.

- In the first part of Hope for the Heartless, Avalina's two first meetings with the Horned King include him concealing himself in shadows for a reason. During their third meeting, he reveals himself fully to her by slowly walking out of the shadows, giving her a major scare at the confirmation to her suspicions about who she's dealing with. While the Horned King's identity is never a secret to the readers, the effect is still strong when the reveal is told from Avalina's POV.

Kaufman goes back to packing his bags into the escape car only to hear a noise. Turning, he turns to see Cholo walking towards him. "You're dead!" Kaufman shouts. Cholo then finally comes into the light, revealing that he had turned into a zombie at some point while walking back into the city, and he's now close enough to do a Deadly Lunge at Kaufman. Kaufman reacts by saying "Oh god, you are dead!" in dismay.

- Captain Hindsight in the South Park episode "Mysterion Rises".
- Played for Laughs in The Simpsons. Bart and Lisa meet a shady figure in a parking garage, and he stands in the shadows as he tells them to investigate Sideshow Bob's successful run for mayor, but refuses to give away his identity.
