Droids was a children's
cartoon series created in 1985 by
Nelvana Animation and
20th Century Fox, starring the two most famous robots in
Star Wars canon,
C-3PO and
R2-D2. The series takes place fifteen years before
Star Wars Episode IV: A New Hope.
The duo starts out the series with no masters, and quickly they find a new master to fill that apparent void in their lives. The lucky duo are the mohawked Thall Jobin and Jord Dusat, who are Speeder mechanics. They then proceed through two more sets of masters over the first season.
The series involves smugglers and traders, riff and raff, and ends up having very little to do with Star Wars, despite the occasional light saber presence. The cost of Anthony Daniel's voice and a very high frame rate helped make this unremarkable series not last past it's first season of thirteen episodes.
One of the more interesting things about this series is that it reveals that C-3PO gains pupils in his eyes, as well as eyelids, some time after Episode III, and must lose them at some point before Episode IV.
