In April 2009, her UNIT command were sent on site after a bus had supposedly vanished into thin air and when a blackened human skeleton emerged from the wormhole, which they were alerted to by DI Macmillan of the Metropolitan Police. She and Malcolm Taylor were called by the Tenth Doctor from the other side of the wormhole; she saluted him over the phone, but quickly denied it when he asked her if she had. He warned UNIT of an alien swarm intent on coming to Earth via the wormhole. She ordered Malcolm to close it, though the Doctor and the bus passengers would be trapped on the other side. When Malcolm refused, she drew a gun on him and ordered him to; when he still refused, she showed surprise at his determination and seemed reluctant to shoot him.
At that moment, a UNIT soldier called out that the bus had returned, except this time it was flying. Magambo rushed outside to see this for herself and was just in time to witness three of the Swarm coming through as well. Calling a Code Red, Magambo and her men opened fire on the creatures while Malcolm managed to close the wormhole after a brief technical malfunction. The Swarm were able to resist the bullets from the soldiers guns, but were no match for the more powerful anti-air batteries and, with some help from the Doctor, they were eventually killed. She thanked the Doctor via a salute and gave him his TARDIS, which UNIT had found in Buckingham Palace's garden. She and her men bore witness to the escape of Lady Christina de Souza first from police custody (though she and her men made no effort to stop her) and then in the flying bus, much to their astonishment and amusement. (TV: Planet of the Dead) She then contacted Alan Mace to inform him of the preceding events. (PROSE: Judge, Jury and Executioner)
Later that same year, she asked the recently-married Martha Smith-Jones to have the Doctor investigate mysterious trees in Greenwich Park. Despite having been the one to get him on the job, she refused to heed the Doctor, and followed the deranged Advocate's advice instead, who tried to blow up London. Fortunately, the Doctor foiled her mad plan. He called Magambo and UNIT "typical military". She angrily told him that if that's how he felt, to leave Earth, and never come back until he changed his face again, because his current one had worn out its welcome. The Doctor and Martha furiously turned their backs on her after these events. (COMIC: Don't Step on the Grass)
Undated events Edit
Parallel world Edit
In a parallel world, Captain Magambo was in charge of a special division of UNIT. She took part in the operation to remove the Time Beetle on Donna Noble's back and with the help of Rose Tyler, sent Donna back in time to prevent the events which would result in the Doctor's death and worldwide disasters.
