Lloyd Collins

 was a worker at Brixton tube station. He was the husband of Devina Collins and the father of Jess and Maxwell Collins.

In 1948, Lloyd came to Great Britain on the Windrush. During the voyage, he met Devina and fell in love. Buying a house in Brixton, London, they married and had two children: Jess and Maxwell.

In 1972, while working at Brixton station, Lloyd was attacked by the animated corpse of a Hakuai called Moan'na. Lloyd fell ill and was taken to Kings College Hospital. The bacterial infection, mutated by Moan'na's biological resequencer, transformed Lloyd into a Hakuai. Lloyd then fled, taking Jess with him. The infection went airborne, but the Twelfth Doctor cured Lloyd by feeding Moan'na's resequencer, keyed to Jess and Devina's familial DNA, to Lloyd, curing him. He used the TARDIS' telepathic circuits to rewrite the DNA of the other infected humans to return them to normal, but this caused the TARDIS to overload, trapping the Doctor in 1972. With nowhere for the Doctor to go, Devina offered him to stay with the Collins family. (COMIC: The Pestilent Heart)
