All euphorics who appear as minor villains (save for ONE) in Speed Grapher qualify. These euphorics, who received superpowers based on their fetishes, use their powers to murder for kicks and giggles. Only four euphorics in the entire anime can be considered stable (if not completely sane), and two of them are major antagonists, the other being The Hero and the last one being The Woobie. Strange case where major antagonists come off more sympathetic than minor antagonists.
