Lucas is the son of Flint and Hinawa, and the younger twin brother of Claus. He lives in Tazmily Village with his family and dog Boney. He has blonde hair and blue eyes,and usually wears a red t-shirt with yellow stripes, blue shorts, white socks, and red and yellow sneakers, although this outfit is temporarily modified when he is confused with the Masked Man (who he has a strong resemblance to). He realizes his PSI powers from Ionia, one of the seven Magypsies. To learn PSI, Lucas is forced to hold his head underwater for a period of time. Until he embarks on his adventure, Lucas has a reputation of being an emotional boy, and almost the exact opposite of his twin brother, Claus. He can show determination, but only when the situation permits. Three years later, Lucas has matured into a boy much like his brother Claus, determined and strong-willed.

It doesn't matter if you're male for female, you can audition for him. Like with Ness, try to sound like a little boy between 10-12 years old, as a 14-year-old teenager, at the very most.
