He is euthanized by Batman by the end of the story.[68] Two-Face also appears in the Elseworlds Daredevil/Batman: Eye for an Eye crossover book, partnered with Marvel villain Mr. Hyde for the purpose of using Hyde as an "incubator" to grow an organic microchip, giving Hyde drugs to speed up this process (regardless of the fact that this would kill him). It is also revealed in this book that Harvey Dent had once been friends with Matt Murdock, who is secretly Daredevil. Prior to his disfigurement, Dent believed in giving criminals a chance at rehabilitation, while Murdock believed in final justice; having reversed his outlook to what Dent had once believed, Murdock talks Two-Face out of killing Hyde without Two-Face using his coin.
