Roy Maddock

Roy is a drug addict with hypersensitivity: basically, he feels the effects of drugs better than anyone else. Begg finds great potential in him and wants to use his threshold to create the perfect drug. Roy, on the other hand, while drugged up, causes a lot of trouble for his girlfriend Edith. He is one of the protagonist in Drugs and Dominos, however due to the dark nature of his storyline, was not adapted into the anime.

1932 Drugs and Dominos
Roy wakes up to one of his highs thanks to Edith. The two argue about his destructive lifestyle before she breaks up with him.

Realizing his folly, Roy plans to set things right by breaking off Begg's drug prescriptions and escape the Runorattas. First he gathers information via the Daily Days, and through there steals a black bag of drugs and a black van before causing an accident that attracts unwanted attention.

Knowing this is a death sentence, he calls Edith for help. The two rekindle with his intention to quit his addiction and start a new life away from New York city. However, the odds are against the couple's favour and Roy needed a scapegoat.

His plan was to distance his association from the Runoratta family by allying himself or blackmailing Eve Genoard and seeking her help to meet with the Gandors. Based on information from Daily Days employee Henry, he goes based on what was best for his and Edith's future.

Eventually he and Eve cross paths and plan to meet with the Gandor brothers, only running into Kate Gandor, wife of Keith. He abandons his plan to use the Gandors after spending time with Kate and Eve by planning to side with them and Edith.

At the climax of the turf war, he was taken with Eve by Claire to the heart of the war with the Gandors and Runorattas. He manages to escape however Begg forces him to take another batch of his newly created drugs while holding Edith at gunpoint.

In the end he attempted suicide by slicing his wrist to escape being used as a guinea pig for drugs by Begg. However, he survived his near death experience and wakes up in Fred's hospital and is pardoned for his crimes by a cover up for the Gandor family. He finally acknowledges Edith's beautiful haircut and overcomes his drug addiction as the two work together with the Gandors for a brighter future.
