Devina Collins was the wife of Lloyd Collins and the mother of Jess and Maxwell Collins. When the Twelfth Doctor was stuck in 1972 without a working TARDIS, he lived with the Collins and became good friends with Devina. (COMIC: Moving In)
In 1948, Devina came to Great Britain on the Windrush. During the voyage, she met Lloyd Collins and fell in love. Buying a house in Brixton, London, they married and had two children: Jess and Maxwell.
In 1972, six months after her daughter encountered the Twelfth Doctor, Devina went to King's College Hospital when she heard Lloyd was being kept there. She met the Doctor, who was there with Jess. The Doctor told her to comfort Lloyd while he and Jess investigated the alien cadaver that Lloyd's disease originated from.
As the Doctor and Jess were gone, Lloyd began transforming into a Hakuai monster. When they returned he had fully transformed. Lloyd went berserk and Devina and the Doctor were knocked off their feet. Lloyd then grabbed Jess and flew out a window. Devina and the Doctor followed Lloyd until he landed on the roof of a building. Using one of his devices, the Doctor let Devina and Jess psychically communicate with Lloyd and remind him who he really was. When that didn't work, the Doctor took things into his own hands and cured Lloyd and everyone else that had been infected at the cost of sacrificing his TARDIS.
Two days later, the Doctor visited Jess and told her that his TARDIS would repair itself, but it would take a while. Devina overheard this and invited the Doctor to live with them while he was stuck on Earth. (COMIC: The Pestilent Heart)
The next day, Devina walked in on the Doctor trying to improve her stew. Devina insisted her stew couldn't be better, and when the Doctor tried to make it better with umamium particles and molecular excitation, it turned green and exploded. With the kitchen splattered in green stew, Devina almost kicked the Doctor out, but he quickly cleaned it all up and handmade a new stew which Devina found acceptable. (COMIC: Moving In)
After Jess and the Doctor saw Walter from across the street behaving strangely, on Christmas Eve, the Doctor saw Walter throw a snowglobe through his window. The Doctor, Jess and Devina broke in to help Walter, but no-one else was in the house but Walter. Through the guilt of losing his mother Carmen in 1971 and being left alone for too long, Walter imagined the fictional character Obadiah Grimm murdering the Doctor, Jess and Devina with the touch of his hand. Walter was taken away in an ambulance to treat his mental illness. Devina felt ashamed that she forgot about the anniversary of Carmen's death on Christmas Eve, and promised to follow Walter to the hospital to make sure he got the care he needed. After Devina returned from the hospital, she worked with Jess to prepare a breakfast on Christmas morning, where the whole street was invited as a reminder that they were a community and to remember Carmen.

In 1973, the Collins family were knocked out by Katya Dabrowski and her men, and taken to an apartment in central London. They were greeted by the Master, who told them the Doctor was a threat to them and a powerful and deceitful alien. Ensuring the Collins family that the Doctor would never hurt them again, the Master used the artron energy in their body as a means of opening a portal to a time locked dimension, which they were also sent to. Jess, Devina and Lloyd were separated from Maxwell. A tentacle in the dimension caused Jess' leg to necrotise, making it harder for her to walk. A tentacle in the dimension caused Jess' leg to necrotise, making it harder for her to walk. While trying to escape from alien creatures across a ridge, Jess and Devina saw them age Lloyd to dust.
Maxwell reunited with Jess, and a being called Kiadine, who the Time Lords had imprisoned on this world, reversed what had happened to Lloyd. The Master found Kiadine, and was offered his temporal powers, and the Doctor and the Master fought with each other over the power of the chronon storm, when the Collins family pulled the Doctor back, standing together against the Master. The Master attacked them, and this blast was repelled with the same artron energy in the bodies of the Collins family that had brought the Master to the dimension. The temporal effects on Jess and Maxwell were also reversed. The Master survived this attack and left, and with no-one left to keep time in check, the Doctor and the Collins family evacuated. After Gabriel's funeral, the Doctor said goodbye to the Collins family and left in a fully repaired TARDIS, believing he had outstayed his welcome. (COMIC: Doorway to Hell)
