3000

In 3000, the Tenth Doctor and Martha Jones were trapped in the Mega Bank in Tokyo, Japan, having followed two gangs of alien robbers there through time from the Caribbean Sea in 1800. The Yedari gang in particular wanted to make sure that the duo were sidelined in the dispute, so they gassed the Doctor and Martha. The two nevertheless managed to escape and follow the gangs to yet another time period. (COMIC: Operation Lock-up)
