Eoleo

Eoleo (レオレオ Leoleo) is the son of Briggs and Chaucha from Champa. On several occasions he is seen using Psynergy which leads the player to believe he is an Adept. It is assumed that Eoleo used his Psynergy power to free Briggs from the Alhafra prison which allowed Briggs and his crew to escape to steal the ship.

It is revealed through Chaucha that Eoleo obtained his powers when he was struck by a falling Psynergy Stone, in much the same way as Feizhi and Tret gained their respective abilities in Golden Sun.

Dark Dawn
Eoleo appears as a party memeber in Dark Dawn, where he is a Mars Adapt and prince of Champa. He is described as "free, wild, and filled with a sense of justice".

Quotes

 * On the sailing ship in Alhafra:
 * Eoleo: Goo goo ga ga! (Eoleo uses his Psynergy to make a vase float in midair)
 * Chaucha: Eoleo's only just recently started doing that... After that gem fell from the sky and hit him. He was overcome by a terrible fever, and when he recovered, he had this power.
