List of Danny Phantom Characters - Main Characters

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.

Sam is often the most pragmatic of the group, but she can be bossy at times and determined to stand up for what she believes in, particularly when environmental causes are involved. But she is also very warm and caring and is always there for Danny no matter what. She was the one who urged Danny to explore the then-under-construction Fenton Portal, resulting in the accident that gave Danny his ghost powers. Her favorite ice cream has black icing and gummy bats. She has a crush on Danny that lasts throughout the majority of the series, and she eventually becomes his girlfriend.

Sam has also been unintentionally responsible in the development of ghosts. In the episode "Urban Jungle", Undergrowth brainwashes Sam into becoming his queen and "personal care taker of everything green". In the episode "Memory Blank", Sam causes Danny to lose his powers out of anger because of the wish-granting ghost Desiree and also brings to life three ghosts from a horror movie, Femalien, Terminatra, and Nightmerica.

Tucker is easily corrupted by his vice and gets jealous quickly, often feeling inferior to Danny and Sam. He is strictly a meat-eater, in contrast to Sam.

When she secretly discovers her brother's secret identity, Jazz has quietly made excuses for him while he went out to fight ghosts, and slowly starts to realize that her brother is growing up fine on his own. Along the way, she learns to appreciate her family's ghost hunting and actively takes part at times. She has also learned to embrace her sixteen-year-old self instead of acting like an "adult in a teen body".

Jack is the most obsessed with ghost-hunting. He jumps into action before thinking and can make a bad situation even worse. While he can often act clumsy and incompetent, he holds a great deal of courage and is an adequate fighter, at one point clashing toe-and-toe against Vlad Plasmius and defeating him, much to the latter's surprise and embarrassment. He is a genius who has a good amount of technical knowledge, and is able to conjure up working ghost gadgets and defense systems built all around the Fenton household. He also has a maturity and seriousness that few people recognize and can get serious and show great skill when danger threatens his loved ones.

Maddie (short for Madeline) is an accomplished ninth-degree martial artist who serves as Jack's partner and equal inventor of Fenton anti-ghost gadgets. She is more down-to-earth than her husband and often supports or keep her husband from getting into trouble or harm. She is often the more sensible of the two. Vlad Masters has been in love with her for twenty years ever since college and has spent time trying to win her heart, developing his obsession for her by programming a Maddie hologram to shower praises on him.
