Erisa Magambo

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

History
In April 2009 her UNIT command were sent on site after a bus had vanished into a wormhole. She and Malcolm Taylor were called by the Tenth Doctor. 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 pointed her gun at him and insisted.

The Doctor got the bus back and Malcolm closed the wormhole, but three of the Swarm got through. Magambo and her command fired on them and dispatched all three. She thanked the Doctor and gave him his TARDIS. UNIT had found it in Buckingham Palace's garden. (DW: Planet of the Dead)

Later that same year, she asked the recently married Martha Smith-Jones to have the Doctor investigate mysterious trees in Greenwich Park. She refused to heed the Doctor, but followed the deranged Advocate's advice instead, trying 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 not come back until he changed his face again, because his current one has worn out its welcome. The Doctor and Martha furiously turned their backs on her after these events.(IDW: Don't Step on the Grass)

In November 2009, Magambo arranged for 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. She was part of 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.
