Darth Vader, a known Sith Apprentice.
A Sith Apprentice was a rank given to Sith who were below Sith Masters. The Rule of Two consisted of one apprentice that would train under one master, with the apprentice becoming the master after the old master's death. The apprentice could also be stripped of their rank should the master decide to, and they will usually be terminated by the master in order to keep the Rule of Two.
