Travel through space and time aboard the TARDIS, sightseeing and saving lives
Mickey Smith was an auto mechanic and resident of the Powell Estate who came to befriend the Doctor, Sarah Jane Smith, Captain Jack Harkness, Jackie Tyler and another world’s Peter Tyler by virtue of his youthful romantic relationship with Rose Tyler.
An apparently typical teenager — obsessed with football, sex and alien conspiracy theories — he rose to become a principal defender of not just one, but two planet Earths.
After years of living with the Tyler family on a parallel Earth, he returned to his “home Earth” and married Martha Jones. Despite close ties to the Torchwood Institute of a parallel Earth, he and his wife ultimately struck out on their own to become “freelance” alien fighters.
