Tired of her husband, Tess decided to take control and have herself and her children, Sadie and Billy move out of Carrington Cottage, Colorado.
During an argument with her husband regarding this, a strange dog entered the house and briefly watched the argument before a mysterious influence caused the dog's symbiote, Hybrid to split into four and begin violently bonding to the family. Tess herself ultimately fell victim to the Agony symbiote.
The family, with new purpose, drove to New York, and were made to hunt down Normie Osborn for his codex. Tracking him to Rex Strickland's warehouse in Manhattan, the symbiotes encountered resistance from The Maker, but Agony managed to burn through his weapons with her acid breath. However, Maker was able to detach them from the symbiotes and kept them in his test tubes.
Powers:
-Seemingly those of the original Agony, Leslie Gesneria (Agony) of Earth-616.
-Purple Symbiotic Costume: Agony possessed all the powers the original Venom symbiote had, including an ability even her "father" did not have. Unfortunately since Leslie could not properly control her "other," and the fact that she died early on in her career, Agony only displayed some powers granted by the symbiote.
Her full range of powers would have consisted of: -Superhuman Strength -Superhuman Durability -Superhuman Stamina -Accelerated Healing Factor -Wall-Crawling -ESP (Spider-Sense) -Immunity to Spider-man's Spider Sense -Webbing Generation -Camouflage Capabilities -Constituent-Matter Generation -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 chemicals (such as Spider-Man's artificial webbing.) This ability has not been shown in any of the other LF symbiotes.
Weaknesses:
-Intense Sound: The symbiote is extremely sensitive to high frequencies of sound and Sonic attacks. This was best exhibited when Trevor was killed instantly by Donna using a Sonic knife. -Intense Heat: The symbiote is also vulnerable to intense levels of heat.
