[2] The peaceful people of Gandahar are suddenly attacked by an army of automata known as the Men of Metal, that march through the villages and kidnap their victims by turning them to stone.

On his journey, he encounters the Deformed, a race of mutant beings who were accidentally created via genetic experimentation by Gandahar's scientists.

The two stow away on a nearby boat which heads towards the middle of the ocean where they encounter Metamorphis, a giant brain.

Sylvain and Airelle are captured and confronted by Metamorphis, who tells them that although the Men of Metal believe that he is their leader, he did not create them nor order their attack.

He then returns Sylvain and Airelle to Jasper where they learn that Metamorphis, like the Deformed, was also an experiment by Gandaharian scientists.

He comes across the Deformed, who explain the true nature behind the Men of Metal: Due to Metamorphis's now advanced age, his cells can no longer regenerate, which drove him to create the Men of Metal and order them to go back in time to capture the Gandaharians so he could absorb their cells to continue living, killing the Gandaharians in the process.

[5] On October 28, 2023, a fan group known as The Gandahar Restoration Project released an English dub on YouTube.

Though the restored version claims to be uncut, the creators do admit that four seconds of French dialogue was cut from the release as that footage did not fit with the English dub.
