Archibald Corduroy is the secondary antagonist of the Gravity Falls episode "Northwest Mansion Mystery", with Preston as the real main antagonist. He was a lumberjack who helped build the Northwest Manor and was later swore vengeance after being betrayed by the Northwest family.

Although not explicitly stated, he is almost certainly an ancestor of the show's supporting protagonist Wendy Corduroy, due to having the same last name as her and bearing something of a resemblance to her father, Manly Dan Corduroy.

He was voiced by legendary voice actor Kevin Michael Richardson.

Past
The ghost was originally Archibald Corduroy, a lumberjack and construction worker who, 150 years before the events of the episode, was one of many lumberjacks who agreed to help build the Northwest mansion. Nathaniel Northwest had promised the lumberjacks that their contribution would be a service to the town, in the form of a grand annual party for the rich and common folk to share (presumably this promise was made in lieu of actual payment). The work took many years and many of Archibald's fellow workers died in its construction, but eventually the mansion was complete.

However, when he and the others returned to the mansion to celebrate at the party promised, Nathaniel and his wife simply laughed at them and shut the gates in front of them, showing that the Northwests had never intended to keep their promise of letting them in. This saddened Archibald and his friends, but while the others choose to leave, Archibald became enraged that his people had toiled for nothing. He threw his hat to the ground and banged at the gates, furiously demanding that they honor their promise. As rain began to pick up on the mountainside, an unforeseen consequence of his labor occurred adding injury to insult. With the trees gone, the soil surrounding the mansion was loosened and an enormous mudslide swept the lumberjack away. And as the Northwests and their guests partied away, Archibald held onto a stump to keep himself from being swept away. His last sight before death was an axe that was sent flying towards him and piercing his head, killing him at the very foot of the mansion he had built.

With his dying breath, the lumberjack swore a curse on the the Northwest family; if they hadn't kept their promise and let the common folk into there party within the next 150 years, he would return and wreak his vengeance on their descendants and anyone else within their home. Nathaniel saw this heard this chant and wrote it down on a piece of paper, which passed down through generations of the Northwests And despite believing in the curse and knowing how to lift it, they continued to disallow any of the townsfolk into their home, believing their reputation was more important than their very lives.

Present
Upon the eve of the annual party, after one and a half century had passed since Archibald Corduroy's demise, the Lumberjack Ghost began his attack on the Northwests by caused their possessions to fly around. The current patriarch of the family, Preston Northwest foresaw this event, but instead of adhering to the ghost's demands, he instead forced his daughter Pacifica to trick Dipper Pines (then a minor local celebrity for his many victories over the forces of the macabre) into getting rid of the ghost in order to avoid ghostly justice.

Pacifica leads Dipper to the source of the disturbance: a room with a fireplace, several animal heads and a portrait of Archibald Corduroy himself. As Dipper investigates the area, the man in the picture vanishes, the animal heads began bleeding and chanting and the furniture starts flying around. Then the ghost himself materializes straight out of the fireplace, starting with a skeleton with an axe lodged in its skull, then flesh and clothes form around it, and lastly grows a beard made out of ghostly blue flame. Smelling the blood of a Northwest, the Lumberjack Ghost summons an axe and starts searching for Pacifica. Upon finding them, he chases them throughout the house until they fall into a secret room. The ghost ambushes them and attempts to kill Pacifica until Dipper entrapped him in a silver mirror.

The Northwests thank Dipper for getting rid of the ghost, but as he leaves, the ghost laughs at him and reveals his past and motivations behind attacking the family, and that Dipper was merely a pawn just as he once was in the past. Furious at the Northwests for their deception, but knowing the ghost was too unstable to let free, Dipper began the exorcism process. Failing to convince Dipper into setting him free so that they could both have revenge on the Northwest family, the ghost tricked him into letting him look at the trees one last time. Drawing power from within the mirror the ghost used his flaming beard to heat up the mirror's metal frame, forcing Dipper to drop it. Upon hitting the ground the mirror shattered and released the ghost, allowing his revenge to be completed.

He then returned to the party and attacked everyone inside, bringing taxidermy animals to life and transforming the guests into wood, as well as causing trees and plants to grow wildly in the mansion. Dipper tries to confront him, but this time the ghost overpowers and turns him into wood as well. Once all the guests were turned to wood and the mansion reclaimed by nature (described by the ghost as a "Forest of Death"), he then began the final step of his plan; to set the mansion and the "Forest" ablaze and burn everyone to death. However, spurred by Dipper's sacrifice, Pacifica defied her parents and opened the gates to mansion, finally letting commoners into the party for the first time in 150 years.

With Pacifica having finally fulfilled the promise of her ancestors, the curse was finally broken and guests and mansion were returned to normal. The Lumberjack Ghost was overcome with joy as his work is finally done. Thanking Pacifica for doing the right thing, saying that he feels 'lumber justice'. The ghost happily passes away to a peaceful afterlife, leaving only the axe that was in his head.
