Leader of evil crime syndicate COBRA in the GIJOE cartoon series of the 80s. His face is always covered, at first with a hood, and then by wa variety of helmets as the series progressed.
If only Cobra Commander listened to Dr. Mindbender's advice he would have suceeded in destroying GIJOE.
When some resigns or retires from a job, they are on "eternity leave". This can also refer to someone who has passed away, especially someone who worked somewhere for a long time, retired/resigned, then passed away later.
Oh I'm sorry, you didn't know that Kelly is on eternity leave? She resigned and moved to Hawaii!
With regrets I would like to inform you that my boss is officially on eternity leave. I will never see or hear them again. Ever.
