Warlord (vol. 1) #20 (April 1979)
Written and Pencilled by Mike Grell; Inked by Vince Colletta
- Deimos bears some resemblance to the Wicked Witch in Wizard of Oz (1939): he watches his enemies in a big crystal ball, and he's got winged monkeyish servitors.
Grell reaches into the mythic storytelling tropes well to pull out a little father-son conflict here, which echoes through Greek mythology, Le Morte D'Arthur, Shelley's Frankenstein, and Star Wars.
The name of the foreboding Terminator region where Deimos's castle lies has nothing to do with killer robots from the future, but instead derives from (the misapplication of) the astronomy term for the dividing line between the bright and shaded regions of the disk of the moon or an inner planet. It also helped, I'm sure, that it has then same Latin root as "terminate," both deriving from terminus, "boundary marker."
