Drako

Drako was a Korad and the leader of a haven on Mechanistria. When the First Doctor arrived nearby, Drako sent a soarer to rescue him from being run over by a Grukker and take him to the haven. Drako, having informed the Mechanistrians of the Doctor's arrival, learned that TARDIS could travel through space and time. When Beran arrived for the Doctor and the TARDIS, Drako seized Beran's weapon and took him prisoner. He and the Doctor took Beran's soarer to where the TARDIS was being kept and went back in time ten million years, where Drako hoped to prevent the future from coming into being.
