Nightmare Fuel: The Lurker Shark in the first game, and the Kraken tentacle in the third.
- Metal Kor's first appearance. First, this unseen, deep voice says, "Finally! The last Rift Gate has been opened!" and several freaky creatures that look like giant insects come through the portal, followed by some HUGE beast that roars loudly and says, "You cannot hide from me, boy!" I'm pretty sure anyone would shit themselves if something like that happened to them.
- Dark Daxter, contrary to earlier reports, doesn't talk like the Hulk and seems to be of his usual intelligence. What makes this fit the trope is that Daxter is genocidal and bloodthirsty while dark, but everything he says sounds frighteningly in character.
Aww, I broke this one. Still hungry—time for more meat-snacks!
- The boulder chase in the Tomb of Mar in the second game that at first seems to be a Shout-Out to Crash Bandicoot. What really takes the scare factor Up to Eleven is when a giant spider comes out of the bolder.
