Erisa Magambo

Captain Erisa Magambo was a female officer working with UNIT in the early 21st century.

History
In April 2009 her UNIT command were sent on site after the Number 200 Bus had vanished into a wormhole. She, along with Malcolm Taylor, managed to contact with the Tenth Doctor. She was very excited by this as she, like everyone else in UNIT, wanted to meet the Doctor, even knowing that it would only happen when dealing with a major threat. The Doctor warned UNIT that an alien swarm was 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 held him at gunpoint and insisted he close it.

However, the Doctor got the bus back to safety. Malcolm then closed the wormhole. Three of the Swarm gained access to Earth, prompting a code red event. Magambo and her command fired on the aliens and, using a mounted rocket launcher, dispatched all three. She thanked the Doctor and gave him his TARDIS back after UNIT found it in Buckingham Palace Garden. (DW: Planet of the Dead)

Later that same year, she asked the recently married Martha Smith-Jones to contact the Doctor to investigate mysterious living trees in Greenwich Park. During the investigation she chose a scenario proposed by the Advocate, which would cause the death of millions to save billions, rather than listen to the Doctor. Fortunately the Doctor was able to stop their insane plan. He furiously confronted Magambo, referring to both her and UNIT as "typical military". She angrily told him to leave Earth, and not come back until he changed his face again, because his current one has worn out its welcome. Her actions in this affairmade both the Doctor and Martha turn their backs on her. (IDW: Don't Step on the Grass)

In November 2009, Magambo was responsible for contacting Jack Harkness to discover the cause of the time fissure occurring in Cardiff. (TWN: The Undertaker's Gift)

In 2013, Magambo was in charge of the clean-up operation after the Nestene invasion of Hyperville. (NSA: Autonomy)

Alternate Timeline
In an alternate timeline, Captain Magambo was in charge of a special division of UNIT, most likely the sole surviving British division in that world. She was part of the operation to remove the Time Beetle on Donna Noble's back, and with the help of Rose Tyler, she sent Donna back in time to prevent the events which would result in the Doctor's death and worldwide disasters.
