The former president of the galaxy. When they were young, Zaphod and Ford met Yooden while raiding his ship, which was a heavily armored “megafreighter.” Impressed by Zaphod’s ability to get past the ship’s security measures, Yooden welcomed them with “food and booze” before teleporting them directly to a maximum security prison. Later, when he was president, he came to Zaphod and told him to steal the Heart of Gold and find Magrathea. Unfortunately, though, Zaphod doesn’t know why Yooden told him to do this, since Yooden is now dead. What’s more, Zaphod has tampered with his own brain so that the memory is no longer clear. All he knows is that Yooden wanted him—for some reason—to find Magrathea.
