Tropes associated with this work:
- Fantastic Caste System: The Kalen in Atavar have at least a combat and science caste. The combat caste is bigger, broader, and have more square faces than those of the science caste.
- Humanity's Wake: Atavar takes place in a future where humanity is extinct, having left behind a race of robots called UOS. UOS is bent on wiping out all life in the galaxy. Nice going, humans.
- Speech Bubbles: The Uos' speech bubbles are square and all their dialogue is bold. In the first few panels, before Atavar gains the ability to speak their language, the Kalen's dialogue is represented by random Greek letters.
