In "Reign Storm," Jack and Maddie create the Ecto-Skeleton. It is a mechanized battle suit that allows the wearer to fight with power 100 times their normal abilities. The suit is hooked up through a neural interface. Initially, its main drawbacks were that it drained the user's energy at an alarming rate and the neural interface was considered extremely dangerous.
In "Secret Weapons," Vlad put Jazz in the suit and combined it with Technus' lighting rod and the ecto-converter to provide a limitless power source. Vlad also injected Jazz with nanobots so that he could waste her if she tried to get out of fighting Danny.
After Danny and Jazz trick Vlad, Jazz activates the suit's self-destruct sequence in order to prevent Vlad from possessing it.
The Ecto-Skeleton is a large battle-suit, with only a seat inside for the driver. It only fits one person maximum. The top of the Skeleton is a clear dome, which acts as the windshield. There is a logo, a green flame inside it forming a "F", on its chest.
- Physical Augmentation: As stated previously, the suit main ability is that it can increase the user's physical attributes by 100-fold. By wearing just the prototype legs, Jack ran at incredibly fast speeds and could kick with enough force to send the Fright Knight and his horse out of Fenton Works, across the street, and past two buildings. Danny was able to stand up to legions of ghosts and even face off against Pariah Dark. The suit also provides considerable protection/durability against attacks as Danny could withstand hits from Pariah Dark, and even a massive pile-on of ghosts. In "Secret Weapons," Vlad hires Skulker to steal Bloodstream Nanobots, the Fenton Ecto-Conveter, and Technus Lightning Rod to upgrade the Ecto-Skeleton and remove its negative effects.
- Ghost Powers: If Danny Phantom is the user, then the Ecto-Skeleton will also possess ghost powers, such as his Ghost Ray, Ghost Shields, and Duplication. It will even transform itself into Danny's uniform colors, complete with his insignia. This might have been possible because of the neural receptors from the ecto-skeleton. Additionally, the suit will increase Danny's ghost powers by 100-fold and even give him better control over his powers such as duplication.
- Foot Thrusters: The suit flies by means of rocket-motors in the soles of the feet.
- Self-Destruct Device: To keep Vlad from possessing the upgraded Ecto-Skeleton, Jazz activated the self-destruct device, thereby destroying it.
