Basic Trope: A character seems to cross a Moral Event Horizon until he is shown in a full story.
Straight: On the cover of "Troper Comics", series protagonist Bob is first seen grabbing a knife to slash somebody, saying "You deserve this after all you've done". In the book, he's slashing at ropes to free somebody.
Exaggerated: The cover shows Bob dropping a nuke on a city. In the actual story, Bob is actually grabbing the nuke to prevent it from falling on the city.
Downplayed: The cover shows Bob fighting with somebody, implied to be love interest Action Girl Alice, but instead he's fighting Diana in the actual story.
Justified: It was a frameup in story, and the cover easily allows the readers to see how the people in universe saw the hero.
Inverted: The cover for the comic makes it look like Emperor Evulz has done a Heel-Face Turn. Turns out he didn't.
Subverted: Bob is first seen chopping the binds on somebody. It turns out he was releasing a villain.
Double Subverted: Who was actually one of the more Anti-Villain foes of Bob, and who was actively working with him to stop the destruction of the world.
Parodied: The person being released is saying "Oh no, you're holding a knife up to me! What might you be planning to do with that thing?" And in a smaller text box it says "And I bet anybody watching this will get the wrong idea."
Zig Zagged: ???
Averted: Bob is fully shown to be cutting the ropes rather than the person.
Enforced: Bob is usually a pacifist. Showing him 'killing' someone will evoke curiosity among readers and make them want to read on what had happened to Bob.
Lampshaded: On the actual page it happens, police chief Charlie bursts in from what appears to be the place where the cover was looking in from, saying "The way I saw things I thought you were about to hurt somebody!"
Invoked: One of Bob's enemies builds a room so that it would look he was committing a horrible act to Alice
Exploited: The enemy then took a picture of the 'act' and reported to the police.
Defied: Bob loudly exclaims that he's going to free the person and not stab him.
Implied: Bob was helping the freed victim recover from the suspension. The victim was saying "For a second there, I thought you were going to use that knife on me."
