Jack Tyler
From Tardis Wiki, the free Doctor Who reference
Jack Tyler was a man who lived in a rural part of England with his grandmother Martha Tyler. When the Doctor and Leela met him they asked him to keep safe. But he helped them save the planet from the Fendahl, but was almost killed by a Fendahleen. He later escaped the priory with his grandmother after it exploded. (DW: Image of the Fendahl)
