Nicole

Age: 5,000 (But look 14)

Species: Half angel-half devil

    Despite having Lucifer as her daddy, Nicole is a comely sweetheart. She seems to have won Danny Fenton over. Nicole and her half-sis, Angi, are completely different. Angi is jealous of her. Nicole loves Danny as well but they have to keep it a secret.

Danny Fenton/Phantom

Age: 14

Species: Half human-half ghost

    Everyone's a little different, but Danny, well, he's A LOT different. On the outside, he's a nervous, kinda clumsy 14-year-old who wouldn't stick out in a crowd. But underneath that awkward teenage exterior, Danny is a genuine superhero! After an accident in his parents' lab, Danny was given some ghostly powers. Half ghost, Danny can see, hear, and talk to other paranormal beings—not to mention battle them on a regular basis to save his friends, family and, you know, the rest of the planet. Too bad he's still afraid of them!

Angi

Age: 502 (But looks 16)

Species: Devil

    Lucifer's favorite devil daughter, Angi does what she pleases. She has been with many men. Angi is jealous of Nicole. The full devil loves to torture her half-breed half-sister. Angi flirts around with Danny and tries to sleep with him.

Jasmine "Jazz" Fenton

Age: 16

Species: Human

    Danny may have the superhero powers in the family but his sister, Jazz, got the looks, the brains, the social skills, and basically everything else. Just don't ask her the to solve the quadratic equation around her friends—she does have an image to protect, you know. But her smarts aren't the only thing Jasmine hides—she won't tell a soul about Danny's superhero status. Can you imagine the embarrassment if that got out at Casper High?

Yayoi:

Age: 25,000 (But looked 25)

Species: Devil

    Yayoi is Angi's late mother. She is a full devil. She fell in love with Lucifer. They married in December. The bliss was short-lived. Lucifer married Ami while he was still with Yayoi. Jealous, Yayoi had Ami killed. When Lucifer found out the truth, he had Yayoi killed as punishment.

Jack Fenton

Age: N/A

Species: Human

    If Danny seems a little strange, it's probably because bizarre behavior runs in the family. Danny's dad, Jack—determined to prove the existence of ghosts but completely unaware that his son sort of is one—is far too brave for his own good. Geared up in his bright-red "test pilot suit," Jack always jumps into the action before thinking and usually makes a bad situation even worse. Compared to keeping his dad out of trouble, fighting ghosts and surviving high school are practically a piece of cake for Danny.

Ami

Age: 23,000 (But looked twenty-five)

Species: Angel

    Ami is Nicole's late mother. She was an angel. Lucifer lusted after her and kidnapped Ami for herself. They married in hell. But it didn't last. Ami was murdered by demons.

Maddie Fenton:

Age: N/A

Species: Human

    Danny's mom, Maddie, is absolutely brilliant. Need to know why walls suddenly bleed, why possessed statues are reciting Shakespeare, or how to get rid of that ghost that's been following you for days? Maddie's got the answer. But all that time spent with out-of-this-world weirdness (not to mention Mr. Fenton) has kind of rubbed off on Danny's mom. Let's just say you'd sooner find her building a high-tech ghost-tracker than baking gingerbread cookies. In fact, she's probably building one right now.

Jim:

Age: 1,090 (But looks 27)

Species: Half-devil-half-human

    Jim is Angi and Nicole's older half brother. He is half devil and half human. He is obsessed with Nicole. Jim is like Angi, only worse! He loves to torture Nicole as well.

Samantha "Sam":

Age: 14

Species: Human

    Samantha and Danny ARE NOT A COUPLE! They're just really, really good friends who share a psychic connection. Get it? Well, Samantha doesn't care if you don't believe her anyway. This Ultra-Recyclo Vegetarian couldn't care less what other people think of her, which is a good thing since she's into conspiracy theories and all things paranormal. Luckily for Danny, he has a super smart girl FRIEND to help him out his jams.

Tucker Foley:

Age: 14

Species: Human

    If talking was a superpower, Tucker would be the king of superheroes. No matter how many ghosts are chasing him, Tucker just keeps on chatting, and it gets him and Danny into loads of trouble. At least Tucker's knowledge of Danny's powers hasn't gotten in the way of their friendship—although it would be nice if Tucker kept his mouth shut and let Danny handle the paranormal activity.
