Kyle

Kyle (ドリ- Dolly) is the father of Isaac and husband of Dora. He himself is a Venus Adept like his son.

In Golden Sun
Kyle appears briefly in Vale at the beginning of the story. He is first seen urging Isaac and Dora to hurry out of their house while the Mt. Aleph Boulder is falling. Once the family is outside, he and Dora leave Isaac alone, telling him to go to the plaza as they go to help out other villagers. He is next seen at Jenna's house, trying to rescue Felix from the water. After Mt. Aleph's boulder falls upon the house, Kyle is presumed dead.

In Golden Sun: The Lost Age
After lighting the beacon of Jupiter Lighthouse, it is revealed that Kyle is still alive. It turns out he was saved by Saturos and Menardi after the storm three years ago, and is well cared for in Prox.

Kyle meets after three years his son Isaac at the top of the Mars Lighthouse, joined with the parents of Felix and Jenna in the form of the Doom Dragon, and forced to battle Felix and Isaac's party. When the fight is over and the dragon defeated, it's discovered the painful truth, although Isaac said that he knew who was fighting.

But luckly, when the lighthouse is lit, Kyle, along with Felix and Jenna's parents are revived thanks to the power of the lighthouse, and return to Vale, when he meets again with his wife.
