IL-series Cylons typically take on the duties to maintain the non-military aspects of the Cylon Empire, typically commanding bases (The Young Lords) and basestars on important missions for the Empire (Lost Planet of the Gods, Part II, et al.) Unlike the Cylon Centurion, they have two eyes, similar in proportion to the eyes of humans, as well as a less-robotic monotone voice.
Lucifer is the IL-series Cylon that appears most frequently. Specter appears only once, commanding a remote outpost (The Young Lords). Several unnamed IL-Series Cylons are seen milling about at the dedication ceremony on Gamoray (The Living Legend, Part II).
Notes
- The "IL" part of IL-Series may stand for Industrial Light & Magic[citation needed]. It is also suspected to stand for Imperious Leader, since both Cylon types perform similar roles.
