Little has been revealed about Diego's early life. Donna had a history of psychotic episodes, but despite this she passed a background check and became a prison guard. While watching Cletus Kasady and MacDonald Gargan, she was in touch with the symbiotic goo, turning her into Scream.
Powers and Abilities
Powers
Yellow Symbiotic Costume: Scream possesses all the powers and abilities the original Venom symbiote had, including a few abilities unique to herself. While at first Donna could not properly control her "other," Scream eventually began using more advanced powers granted by the symbiote, including camouflage and limited shapeshifting. Her full range of powers 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
Constituent-Matter Manipulation (Hair): An ability unique to Donna's symbiote, Scream can extend her hair-like tendrils to lash at or encircle her foes.
Limited Mental Projection/Sound Manipulation (Sonic Knife): When Donna decided to vanquish all symbiotes and symbiote hosts because they were evil, her schizophrenia somehow crossed with her powers and manifested in the form of a Sonic Knife. With it she slayed her former companions, due to the intense frequencies of sound enveloping the blade being a weakness of the aliens. The knife is eventually destroyed by Venom.
