Lucas (or Luke) McCain is over six feet tall with a lanky build that belies his strength. He has sandy-blonde hair that is kept short and uncompromising light blue eyes. His voice is low and rather quiet when he speaks but rings out like a whip-crack when he barks a command. He typically carries a revolver which almost seems to magically appear in his hand with a twitch of his arm but when real trouble brews, he brings out a lever-action carbine that he carries in a scabbard over his shoulder.
He "knows his way" around a starship, being a better-than-average pilot and seems comfortable with command responsibilities, which he takes seriously. He's reluctant to say much about his past beyond the fact that he's captained ships before.
