'Oh, when you get back to Yochi, tell Yigo this for me: 'You are a complete twat.'' -Kuja, Series I, Chapter 24

Appears in: Series I, Chapter 25

Yigo and Mihako were created by Alexander around the same time as he was experimenting with Kuja's newly developed Magick powers. They were cloned from some of Kuja's DNA but genetically altered so that they would not just be direct copies of him. Yigo was created first and Mihako second. Yigo was granted ½ of Kuja's abilities because Alexander decided that he was a little bit too powerful. Yigo had developed a bit of independent streak and decided to escape the labs he was created in to live by his own means. He and Mihako ran away to the Forest Village and there they set up home. Yigo never got on with Kuja, especially when he found out it was him that was causing all the murders on Yochi. He met his end when he tried to prevent Lierlo from seeing Mihako, causing him to kill him.
