Strontium Dog is a long-running British comics series starring Johnny Alpha, a mutant bounty hunter who lives in Earth's future. The series was created in 1978 by writer John Wagner (under the pseudonym T. B. Grover) and artist Carlos Ezquerra for Starlord, a short-lived weekly science fiction comic. When Starlord was cancelled, the series transferred to the British science fiction weekly 2000 AD. In 1980, Wagner was joined by co-writer Alan Grant, although scripts were normally credited to Grant alone.
