*Danielle "Dani" Fenton, also known by her alias Dani Phantom, is a human/ghost hybrid, a clone and "cousin" of Danny Phantom created by Vlad Masters. She's a younger, female version of Danny, as well as his only surviving clone and only clone that isn't mindless. Dani has taken to traveling around the world in hopes of doing her own heroics.

As Danny's clone, Dani bears a striking resemblance to him, but with the exception of having longer hair tied-back into a ponytail, and is shorter in height due to being a child. She also wore plum-colored lipstick.

Dani's clothing consists of a red beanie, a blue hoodie-sweatshirt, red shorts (plain in "Kindred Spirits" and with a camo pattern in "D-Stabilized"), and shoes that are similar to Danny's, but blue and are larger in size.

In ghost form, Dani's appearance is similar to Danny's, but her suit is two-piece with a crop-top, a baggier bottom, and an asymmetrical white-and-black pattern, and she wears a black right glove and a white left glove. Her voice becomes slightly but noticeably resonant as well.

A rather mischievous and tomboyish girl, Dani shares many of Danny's likes and personality traits: they are both stubborn, like to exchange witty banter during battle, have a shared like for NASA and a dislike for bullies such as Dash. However, where Danny is awkward, shy, and tries to fit in, Dani is more bubbly, playful and socially detached than her "cousin". For example, using her powers in the middle of the Casper High cafeteria (although it is entirely possible that she was trying to get Danny to follow her or simply pulling a prank) and transforming into her ghost form in broad daylight.

When she was under the influence of Vlad, Dani had a somewhat darker personality, faking exhaustion to avoid further questioning from Danny, and boasting about him being too weak to beat her when she was trying to bring him back to Vlad. After changing sides, however, Dani becomes a more willful and independent person, deciding to travel around the world and do her own heroic deeds.

Dani can be rather naïve, in large part due to her young age, believing Valerie Gray's lies that she would free Dani if she led her to Danny.*
