When Shinra, Inc. wanted to build a Mako Reactor near the town, Dyne originally opposed it, but let them do it anyway. When there was an explosion at the reactor, Shinra took revenge on the town of Corel and burned it down, killing his wife, Eleanor. Dyne assumed that Marlene was killed as well. When Barret and Dyne tried to escape from Shinra, the troops fired upon them, causing Dyne to trip and fall into a deep crevice, but Barret was able to grab hold of Dyne's arm, preventing his fall. On order from Scarlet, the Shinra soldiers fired again. These shots landed directly into the friends' arms, causing Dyne to fall, destroying his left and Barret's right hand in the process.
Thinking his friend was dead, Barret adopts Marlene. Dyne, like Barret, has his hand replaced by a machine gun. Dyne was thought to be dead, until Cloud and his friends discovered people being killed in the Gold Saucer. A survivor told them that they had been shot by a man with a machine gun for an arm, whom everyone, unaware of Dyne's existence, assumed was Barret.
The party is accused of being the attackers and arrested. Without trial, they are summarily thrown into the Desert Prison. The party is told by Mr. Coates that they need the Boss's (Dyne's) permission to get out of the prison. Barret meets up with Dyne, who in grief over his family's death, states that he wants to destroy everything, and fights Barret. After Barret wins, he tells Dyne that Marlene is still alive, but nonetheless, Dyne claims his hands are too stained with blood to ever have a right to see Marlene again. His final act is to give his permission for Cloud and his party to leave the prison. He then commits suicide by jumping off of a nearby cliff.
Dyne also appears in the novella Maiden Who Travels the Planet. Since his death, Dyne has become tormented by the memories of his actions, and his Gun-Arm symbolically appears soaked in blood because of it. With the assistance of Aerith, Dyne is able to come to admit he wanted the world to be destroyed when he was alive and is eventually able to free himself from his torment and find solace. As a reward for this, the Lifestream accepts him and he is greeted by a vision of his wife as he dissolves.
Marlene was originally going to be Barret's daughter rather than Dyne's. Dyne originally wanted to fight Barret because he still had someone in this world while Dyne was left with no one.
Dyne is fought after the events of Corel Prison.
