Symbiote Biology: The Agony symbiote covers its host with dark purple biomass mixed with dark pink and boosts its natural abilities to a superhuman level. Possibly due to Earth's environment, it has the ability to manipulate its biomass in a variety of ways.
Muscle Mass Enhancement: Agony had been modified by the U.S. Government to give its user added musculature growth in order to further bolster their physical strength. Enabling the usage and carrying around high end heavy duty ordinance normally found upon a aerial assault albatross.

Metabolic Acid Generation: Agony could also use her metabolism to spit acid, which could burn through most substances, however the full extent or limit and range of her acid projectiles are unknown.
Metabolic Chemical Absorption: Agony could even absorb and redistribute chemicals in different ways, (such as regurgitating Spider-Man's artificial webbing.) This ability has not been shown in any of the other LF symbiotes.

The names (Agony, Screech and Shriek) are fan names for Agony and his host Leslie Gesneria. The fan-name Agony was devised as being a name suited for a symbiote that seems to be a female version of Carnage, due to her appearance and coloration.
The symbiote (and her hosts) wasn't officially named Agony, until Carnage, U.S.A. #2, with James Murphy as host.
