A Berg is a very large aerial vehicle employed by WICKED as transportation during the Maze Runner series. Bergs were also used by the Post-Flares Coalition to spread the Flare. Apparently, there was a large international fleet before the Sun Flares.
In the film adaptations, Bergs have two large helicopter-like blades on either side, with rotatable jet engines on the back that are pointed down when the craft lands. Bergs also have twin GAU-8/A miniguns located towards the front of the aircraft (as seen in the Death Cure film).
- In The Scorch Trials, a Berg appears at the end of the book to pick up Thomas and his group after they fought off the Bulb Monsters. Also used in the movie to bring in WCKD soldiers to find Thomas and his group.
- In The Death Cure, Thomas and his group steal a Berg to escape WICKED's headquarters and get to Denver.
- In The Kill Order, the Post-Flares Coalition used Bergs to spread the Flare in various settlements. Alec and Mark also stole a Berg to get to Asheville.
- "Berg" is German for mountain, possibly referring to the large size. To avoid misunderstandings, it is referred to as "Berk" in this language.
