"Every dead body that is not exterminated gets up and kills. The people it kills get up and kill."
I realized that if this guy were to have a JoJo Stand, it would be "Clint Eastwood." Think about it:
-Clint Eastwood is a song about being useless in the short term, but in the long run becoming useful in the future and that causing happiness. These eye-opening experiences through music that revives you from the "death" of hollow existence and rejuvenates you into a livelier state.
-Gorillaz have used zombies as a motif to symbol people who mindlessly consume without thinking and go on living their lives without individuality, freedom or creativity. This parallels MC's struggle in the start because of the Black Company he works at and living a hollow existence without happiness or satisfaction.
-Finally, MC's interaction with people can be described as "The Good, (ie his friends and those around him who live for themselves) The Bad (those that work for corrupt businesses like the Black Company and lie/cheat people for their own gain) and the Ugly (Zombies)" which fits the riff of the strong and the strong horror inspiration
If I were to guess the stand's ability, it would probably be to prevent infection on himself and those within a short proximity to himself as a short-term preventative treatment to the virus, paralleling how the apocalypse caused him to become lively and break out of the "zombie-like status" the black company put him in. It also has a passive ability to regenerate people and to put them into a more relaxed state.
If we get more of the other main characters, I'll do stands for them, too. I'm thinking MC's best friend would have "The Joker" (Steve Miller Band reference) and the girl would have "Live and Let Die" or "Survivor" depending on how things develop with her and her backstory.
