Cyber-Leader (The Reaping)
A Neomorph Cyber-Leader from the far future attempted to change history by manipulating the Sixth Doctor in 1984.
Biography
In the far future, one of the last surviving Cyber-Leaders found a TARDIS "abandoned on a planet ruined by fire". It tried to pilot the ship to prehistoric Earth and cyberconvert the early ancestors of humanity, but it was unable to fully control the TARDIS. The Cyber-Leader was severely damaged by exposure to the Time Vortex and it crashed near Baltimore in late 1982. After Anthony Chambers discovered a conversion pod the Leader had brought with him, the injured Cyber-Leader planted an earpiece on him to control him.
Using its access to the entire history of the cyber-race, the Cyber-Leader concocted a plan to lure the Doctor to Baltimore by killing Anthony, as he was a family friend of Peri Brown, in September 1984. The Cyber-Leader even created a climate of fear for the Doctor, by tricking him into believing his planned to convert dead humans into Cybermen by using a nonexistent virus by converting Anthony, and brainwashing the Baltimore police. The plan worked and the Cyber-Leader captured the Sixth Doctor.
At one point he found himself saying "8687", but dismissed it as unimportant. To make the Doctor co-operate, the Cyber-Leader elected to make good on any threats by remotely controlling Anthony and crippling his son Nate. The Doctor was forced to pilot the TARDIS to prehistoric Earth, to convert humanity's ancestors. The Doctor tricked the Cyber-Leader into thinking that history had been changed and instead of piloting the ship to a new version of 1984 where Cyberman had been the dominant life form on Earth for millennia, the Doctor took the Cyber-Leader to Mondas in 1984. The Cyber-Leader was considered faulty by its ancestors and taken to be reprocessed. (AUDIO: The Reaping) Presumably, the reprocessed Leader was destroyed during the 1986 invasion of Earth (TV: The Tenth Planet)
