"Are we curious Boss?"
Big Jilly to Dementus
Big Jilly was a member of Dementus' Biker Horde, and a minor antagonist in Furiosa: A Mad Max Saga.
Furiosa: A Mad Max Saga[]
Big Jilly appears throughout several important events of the story. When the horde encounters the lone war boy, he takes the sky blood and impulsively fires it on the ground. He's one of the members that infiltrates Gas Town during the Trojan Horse scheme, and he gleefully drags Praetorian Jack across the sand while tied to his bike.

Big Jilly is one of the five surviving members of Dement's Horde after the Forty Day Wasteland War, with him and Mr. Norton accompanying Smeg while he serves as a decoy during Furiosa's pursuit. During the chase, he's knocked off the motorcycle, but could presumably still be alive.
