Parasite

Parasite's powers and abilities

In particular, Rudy Jones is granted enhanced strength, intelligence, agility, durability, and reflexes by absorbing the energy of other beings. When Jones drains other superpowered individuals, he gains their abilities for a limited period of time until he "runs out of life-energy" and must seek a new victim to "feed on". He is shown to have a heightened sense of perception that allows him to detect the life force and power within other beings.[24] While drawing the energy of ordinary humans is almost instantaneous, it takes a notably longer time in the case of immensely powerful beings, which gives the victim more time to react and free themselves from the Parasite's grip. Following an encounter with the Strange Visitor, however, the Parasite's powers were enhanced and enable him to retain the energy he takes for longer as well as granting Jones the ability to shapeshift; he can now physically morph into his victims right down to their DNA, being able to access their memories, gain their natural abilities, and mimic their voices. The Parasite's biggest weakness is that he also absorbs the weaknesses of his victims and cannot counter such susceptibilities even when he has other abilities that should do so; when he absorbed both Superman and Livewire's powers, he retained the latter's vulnerability to water despite possessing the former's near-invulnerability. The Parasite also maintains Superman's weaknesses, like kryptonite, even when the Parasite in addition already absorbed the powers of non-Kryptonians.
