Adeola Oshodi

Adeola Oshodi was a technician at the Torchwood Institute in 2006, working on the free energy project when the Cybermen invaded. She was finding a place to make out with her boyfriend when they were both captured and 'upgraded', presumably by Cybermen who were able to slip through the breach in spacetime. Her 'upgrades' were all internal, allowing her to be used as a drone by the Cyber Leader through her earpods, which were linked with connective tissue directly to her brain. She was killed definitively when her EarPods were overloaded by a signal from the Doctor. (DW: Army of Ghosts)

Coincidentally, she was also the cousin of Martha Jones, the Doctor's next companion. (DW: Smith and Jones)
