Bill (Dreadnought)
From Tardis Wiki, the free Doctor Who reference
Bill was a worker on the Dreadnought in the 23rd century and the fiancé of Stacy Townsend.
They were hoping to get married at St Christopher's Church in Norfolk when the Cybermen attacked. He and Stacy fled, but he was captured and taken to their hive, where he underwent partial Cyber-conversion.
When the Cybermen took over the Doctor's TARDIS, the Eighth Doctor had Stacy remind Bill of their relationship, which allowed him to override his programming and attack the other Cybermen. They killed him, but the distraction was enough to allow the Doctor to expel the Cybermen from his TARDIS. (COMIC: Dreadnought)
