Leapers also have an Enhanced form that are encountered later in the games. Leapers appear to scout their possible victims by quickly flashing through open vents and rattlings in an attempt to scare its target and suddenly jump out of nowhere with its high speed and agility.

They are able to navigate Zero-G environments, crawling swiftly across surfaces or jumping between them to pursue prey. Leapers have frequently been encountered in all known major Necromorph outbreaks (with the possible exception of the one which befell the Aliens three million years ago). The mummified variants of the Leaper that are seen in the events of Dead Space 3 seem to be a fusion of multiple corpses, rather than the being composed of a singular corpse. They also retain scraps of the clothing they wore in life. Instead of massive fangs, a multitude of fingers have sprouted from around their mouths similar supernumerary limbs and digits have grown seemingly at random from their bodies. In Dead Space 3, the mummified Leapers-like most of the mummified Necromorphs-bear unique and bizarre mutations not seen in their “fresher” peers. The lower jaw is split into two curved mandibles ending in knife-like fangs. In their place is a pair of multi-jointed appendages that bear sharp, bony fangs. The upper sets of teeth are completely gone, along with most of the palate reaching back into the throat. The cranial and sinus areas of the skull appear to have been dis-articulated from the neck, and the jaws have become heavily mutated. The Leaper uses its powerful tail to quickly launch the creature toward its victims or uses it to stab into its enemies in a similar fashion as a scorpion, as seen with Warren Eckhardt. This tail is highly flexible, able to contract and coil into about a third of its original length. The legs are completely re-shaped: the muscle and bone is flayed, fused together, and lengthened into a single limb tipped with a sharp blade of considerable weight and durability. There is a slight lengthening of the vertebral ridges, and the flexibility of the spinal column is increased to help in locomotion. The musculature of the upper arm becomes more developed, and the fingers grow bladed claws for climbing and slashing with the hands becoming dislocated along with the thumbs moved to the back to create animal-like paws. Leapers appear to be made from a single human corpse, with the host body's modifications serving to give the Necromorph vastly increased mobility.
