One good twist could be a character who seems to be the villain turns out to be the hero all along. For example, in a detective story, the suspect who has all the signs pointing to him as the killer is actually trying to protect the real victim from a more dangerous threat.
One example is in 'The Sixth Sense' where the twist is that the main character is actually dead all along. This completely changes the way the audience views the entire story.
One good plot twist could be that the character who seems to be the hero is actually the villain all along. For example, in a detective story, the detective who has been leading the investigation turns out to be the mastermind behind the crimes he's supposed to solve. It completely flips the reader's expectations.

The discovery that the entire world the characters live in is a simulation.

As they dig deeper, they find out that their whole existence is just part of a complex computer - generated simulation, which turns their understanding of reality upside down.
One good plot twist could be that the two characters who seem to be falling in love are actually long - lost siblings. It completely changes the dynamic of their relationship from romantic to a more complex family - oriented one.
Character development plays a role too. If a character has a hidden side that is revealed as a plot twist, it should be consistent with their previous actions and personality to some extent. For example, in 'Shutter Island', Teddy's true identity as a patient rather than an investigator is a major plot twist. But looking back, his strange experiences and mental states on the island can be seen as clues, and his character's journey makes the twist feel more earned.
One great story with a good plot twist is 'The Sixth Sense'. The twist that the main character is actually dead all along completely changes the viewer's perception of the whole movie. It's a brilliant psychological thriller.
One kinky twists horror story could be about a woman who got kinky twists done at a very cheap salon. Later, she started feeling a strange itching that wouldn't go away.

Eventually, she realized that bugs had been living in the hair used for the kinky twists.
A great story twist can be found in 'The Usual Suspects'. The ending where it is revealed that Verbal Kint was actually Keyser Söze all along is a masterful twist. It takes the entire story that you've been following and flips it on its head. You thought you knew who the characters were and what was going on, but in the end, you realize you were completely misled.
