A Griever is a creature that lives in the Maze and comes out mainly after dark (this is not always the case, they have sometimes been known to come out in the daytime). Its purpose is to harass and even kill the Gladers who venture into the Maze.
It is described as being a bulbous, dark creature, with many appendages such as spikes, shears, and rods. It seems to move in a forward roll. A Griever can "sting" Gladers, or prick them, which causes extreme pain for up to days or weeks. Stung Gladers who take the Grief Serum usually regain some of their memories during the painful "Changing." If a Glader does not take the serum, they die.
Grievers make whirring and clicking sounds when they move. The machinery inside of them often causes the reflectance of light, as described by Thomas. Grievers have stung four major characters in The Maze Runner: Alby, Ben, Gally, and Thomas.
Grievers appear to be easily tricked, as seen when Thomas and Minho tricked the Grievers into going over the Cliff. It is unknown if the Grievers intended to go into the Griever Hole. They are assumed to "charge" in oblong cell-like cages seen in WICKED headquarters and at the end of The Scorch Trials.
In The Fever Code, Doctor Paige says that Grievers have a mutated version of the Flare that can be healed with the Grief Serum. Grievers also appear when Minho is being told off for sneaking out at night. Thomas (and the others who were involved in sneaking out from the WICKED complex) are forced to sit down and watch Minho being tortured by the Grievers through CCTV. Thomas tried to struggle away, when he was watching Minho, but he was forced to watch it by Randall and two other members of WICKED. When Randall had decided that Minho had had enough, he tried to get the others to 'turn off' the Griever. However, nobody seemed to hear him so he tried again to get them to stop it before it could sting Minho. Finally, Randall was heard and the Griever was turned off just before Minho was stung. The memory of that incident traumatised Minho for the rest of his time in WICKED before entering the maze. It is later revealed that Minho went through this multiple times (once for each person who was involved in sneaking out) so they could all see the consequences of sneaking out.
In the Maze Runner film, the Grievers resemble gigantic spiders. Their sting causes symptoms like being uncontrollably aggressive, dark veins being visible. It does not become clear whether it also brings back some fragments of memory. In the film, Ben gets stung by a Griever and subsequently goes through the Changing. Unlike in the book, this means the symptoms of a Griever sting, not the Grief Serum, like being uncontrollably aggressive, small bits of memory coming back. Grief Serum is unknown, though Teresa finds two syringes with unknown content in her pocket. One is used on Alby after he was stung by a Griever, healing his infection. It is confirmed later on that the Grievers use a mutated Flare virus that can be cured with the serum.
