Ramsey Rosso

Ramsey was treated like a porcelain doll when he was little. He discovered what the word "hemophiliac" meant when he had an emergency on the playground and almost died from the amount of blood loss he had from a cut. As an adult, he got a job at the morgue in Central City.

Ramsey began experimenting with the properties of blood, which ultimately led to him gaining powerful new abilities and adopting the name Bloodwork. When The Flash found out Ramsey was stealing evidence, he came to stop him but was inflicted with tremendous pain through Ramsey's power to control blood.

Sometime later, Bloodwork was invited to join the Legion of Zoom, a group created by the Reverse-Flash to bring the hero's greatest villains together to finally defeat him.
