Lucas is one of Ness' best friends, and is a psychic like him, but is a bit weaker than him. He's very shy and has a hard time opening up to people, but when he gets to know someone, he's as loyal as they come and becomes more comfortable. He does have hidden potential, but needs to be provoked to draw out more of his power, similar to Erston. His voice is more innocent than Ness as he is more timid.
