3 wishes ehh. I've always told myself what i'd want if i only had one wish.. But heres 3, With #1 being the one wish.
#1, Immortality. Yup.
#2, Inability to feel pain (Immortality great, But if "Baccano!" told you anything its that pain along with immortality = bad mix.)
#3 Teleportation (Cause no one likes being trapped in a government facility. and just cause your immortal and don't feel no pain, Don't mean they cant capture you.) And since your immortal and feel no pain you wont have to worry if you accidentally teleport inside something or someone and your atoms getting messing up! :D
