Dementus
Background
Dementus is the leader of a biker horde. He once had children. His horde includes the Roobillies and the Mortifiers.
During the events of Furiosa: A Mad Max Saga (2024) played by Chris Hemsworth
As The History Man is telling Dementus the history of the JRl Cycles Lucky 7, Furiosa is brought into Dementus' tent by Rizzdale Pell. Dementus asks Furiosa what her name is and the Organic Mechanic inspects Furiosa's teeth and hands. He tells Dementus that Furiosa is a healthy, flawless, full blood. Dementus asks Rizzdale how he knows Furiosa is from a land of abundance and Rizzdale tells him that a Roobillie told him. Rizzdale has Snapper and Hungry Eyes bring the dying Toe Jam into Dementus' tent and Rizzdale tells Toe Jam to draw a map or arrow in the sand. Furiosa charges at Toe Jam and starts kicking him and Toe Jam dies.
Dementus whistles and then tells Furiosa he will take her home tomorrow and has Sad Eyes feed Furiosa while Snapper and Hungry Eyes watch over her. Later, Sad Eyes runs to Dementus' tent and tells Mr Harley to shoot Mary. Mr Harley hesitates and Fang takes his rifle from him and shoots at Mary, hitting the extra fuel tank on the back of the motorcycle that Mary Jabassa is fleeing on with Furiosa. Dementus uses Dementus' Dogs to track Mary and Furiosa, but Mary ambushes and kills several of Dementus' men. Eventually Mary is surrounded and overwhelmed by Dementus' gang and is taken away. Furiosa runs to where Mary is being crucified on a tree and being tortured by The Octoboss. Furiosa runs towards Mary but is grabbed by Dementus and forced to watch as Mary is tortured.
Dementus and his horde are chasing another group who end up cornered at a cliff. Their leader is chained up to five motorcycles and Dementus tells the rival groups surviving members that there are twenty of them, but only five motorcycles and they must fight to see who shall join his horde. Dementus throws a bunch of weapons on the ground and the survivors are forced to fight to make it onto one of the five motorcycles. Mr Norton goes for a weapon but is kicked in the face and then hit in the face with a hammer. She gets back up and takes Mr Davidson's gun and shoots the member of the group that had attacked her and sits on the motorcycle he had claimed. Dementus tells Furiosa she doesn't have to watch and then gives her the teddy bear that belonged to his children. Dementus then has the five survivors quarter their former leader and Furiosa drops the teddy bear. During the evening, Organic Mechanic serves Dementus lizard mince and human blood sausage.
As Dementus' horde is moving, Smeg points out to Dementus red smoke in the sky. Big Jilly asks Dementus if they are curious and Dementus has his horde head towards the smoke. They come across Lone War Boy with a dart stuck in his forehead who asks them if he is in Halvalla and then correctly calls it Valhalla. The History Man explains to Dementus what Valhalla is and Dementus tells Lone War Boy that they are looking for a place of abundance which Lone War Boy assumes him to mean the Citadel. As Dementus is talking with the Lone War Boy, the Organic Mechanic assesses the Lone War Boy, while Big Jilly takes the Lone War Boy's flare gun. Big Jilly then fires a red smoke grenade into the ground, covering everything nearby in red paint.
The horde travels to the Citadel causing The Wretched to run for cover in their underground warrens. Dementus and his horde arrive in the center of the Citadel and loudly rev their engines. The History Man introduces Dementus, who now calls himself The Red Dementus. Dementus tells the inhabitants of the Citadel to throw down their leaders and they will rule together in the splendor of a new wasteland. Immortan Joe walks out from an opening of a cliff along with The People Eater, Rictus Erectus, Scrotus, The Prime Imperator, and Shotgun Praetorian.
Dementus introduces members of his horde and afterwards The People Eater picks up a microphone and tells Dementus to choose one warrior from his horde. He then tells Dementus to choose a War Boy. Dementus has Smeg choose a War Boy and Smeg points to a group of War Boys. At first First Pick War Boy steps forward, but Smeg says he chose Chosen War Boy. Chosen War Boy sprays himself in the mouth with silver spray paint and Immortan Joe tells him he is awaited. Chosen War Boy then takes two explosive spears and leaps to his death, causing a large explosion when he lands. The People Eater then says that anyone of Immortan's Joe's War Boys will do the same and calls Dementus and his horde fools. Scrotus and Rictus then take the microphone, introduce themselves and tell the horde they are going to kill them. The War Boys then start attacking the Horde who start to ride away. A Wretched grabs Furiosa and tries to drag her to Corpse Minder, but Dementus manages to pull her away and they escape. Later, Dementus and his horde wait as a war rig arrives at Gastown from the Citadel. The next day, as the war rig leaves Gastown, Smeg runs and signals to members of the horde that are waiting to ambush it. The war rig is overtaken and Rizzdale tells Dementus that they have fuel for months. Dementus tells Mortiflyer Matt to remove his helmet and jacket and then tells Mortiflyer Matt to cover himself in white clay. Dementus tells The Octoboss to cover more of his men in white clay.
The Guardian of Gastown at first doesn't fall for the trick and Dementus has his horde start to kill the disguised Mortifiers and Mortiflyer Matt is killed. Guardian of Gastown orders the gates to be open and the war rig makes it inside Gastown. Mr Norton, Mr Davidson, Fang, Big Jilly, Mr Harley and Squint then sneak out of the war rig and force Gastown Gate Openers to open the gates. Immortan Joe agrees to a meeting and during the meeting is guarded by Watch Tower Praetorian Guards while Praetorian Pup hands out food. Rizzdale walks in first and tells Immortan Joe that if they are not back to Gastown by sunset then Gastown will be blown up. Dementus follows behind carrying a contraption with a harpoon pointed to the back of Guardian of Gastown's head. Dementus lists his demands and releases the device when Rictus grabs for the bomb code input device and Guardian of Gastown is killed. Immortan Joe notices Furiosa, who is standing in the back and Dementus says Furiosa is his daughter, Little D. Immortan Joe calls Furiosa pale and the Organic Mechanic tells him that she is pale, because the Organic Mechanic takes her blood to make blood sausage for Dementus. Immortan Joe asks Furiosa if she wants to stay with him and eventually become one of his wives. The History Man tells Dementus that they will be bonded by blood. Immortan agrees to make a deal in exchange for Furiosa and the Organic Mechanic. Before leaving the meeting Dementus takes back the teddy bear from Furiosa and declares that he shall now be known as The Great Dementus.
