Tony Barker

Tony Barker was the brother of Amy Barker.

While playing hide-and-seek in a commons in 1966, Tony and Amy came across the unlocked TARDIS and decided to investigate, only to be locked inside.

After the First Doctor returned and travelled to the Sense Sphere, Tony and his sister helped the Doctor to escape punishment by the Sensorites for killing one of their revered Zilgans. After escaping back to the TARDIS, the Doctor fed the children and returned them home. (PROSE: The Monsters from Earth)
