Ramsey Rosso (Earth-1: Pre-Crisis)

"Even in here, fate continues to cast me in the role as savior."

- Ramsey Rosso

Ramsey Rosso is a scientist who was hellbent on protecting humanity using Dark Matter-powered blood, later operating as the serial killer known as Bloodwork, as an adversary of The Flash.

Reign of Terror
In December 2019, Rosso started infecting The Flash, then many others, only to be incarcerated in A.R.G.U.S.

Visited by Frost
In February 2020, Rosso was visited by Frost in A.R.G.U.S.

Helping the Reflections
In April 2020, Rosso was visited by mirror versions of Kamilla Hwang, David Singh, and Iris West-Allen in order to obtain his mutated blood for McCulloch's plan to escape the Mirrorverse.

Escape from A.R.G.U.S.
Whilst still a prisoner at A.R.G.U.S., Rosso was recruited by Magog and transported to Keystone City in 2049. Whilst there, he began a rampage on the Van Buren Bridge until engaged by Martian Manhunter. After Magog's defeat, Rosso was not returned to his cell, despite the other villains being returned to where they came from.

Former Powers

 * Haemokinesis: Rosso had the ability to control and manipulate blood, and consequently control the body. Through this ability, Rosso was able to feed on the adrenaline-infused blood and increase his own strength.
 * Blood Constructs: Rosso could construct small sludge-like blood from his body and transfer it to another person. Rosso was also able to dematerialize himself into a similar sludge.
 * Transformation: At full strength, Rosso was capable of transforming into an enormous and monstrous creature, which allowed him to take on other heroes, such as The Flash.
 * Superhuman Strength: Rosso was able to easily grab the neck of Reflections and strangle them with ease.
 * Retrocognition: Rosso retained his memories from before Crisis.

Former Weaknesses

 * Hemophagocytic Lymphohistiocytosis (HLH): Prior to becoming a Metahuman, Rosso suffered from HLH and was the major cause for his search for self-preservation.
