Ringway

Ringway was a crew member on a massive space freighter in the middle of space.

He did not really like Captain Briggs because he got ignored by her. When everyone found out about he was working with the Cybermen, he held Captain Briggs, Berger, Adric and the Doctor hostage.

When the Cybermen found out that there more than ten crew members when Scott and his troops moved in, they killed Ringway because they thought he lied. (DW: Earthshock)
