Danny Phantom (David Kaufman) is the main character and protagonist of the series. Originally, he was a shy, average, clumsy, and occasionally superficial 14-year-old boy who was desperate to fit in with his peers and be accepted. After a lab accident in his parents' ghost lab, he becomes a half-ghost, and obtains a variety of ghostly abilities. A battle with a Lunch Lady Ghost placed the unsure Danny on the path to becoming a hero. Despite his flaws, he is steadfast and loyal to his friendsand family. He eventually grows, gaining great confidence and maturity in himself and begins concentrating more on his heroic duties.
He is constantly under pressure from his rival and arch-nemesis Vlad Masters, who wants nothing more for Danny than to have him as his son and apprentice, a desire which is proven in a few of the episodes. His attempts are futile, though, and he remains Danny's enemy.
