Whereas my previous theme related post focused on friendship which reflected the story of Enzo and the bird, these themes are the existing themes present in the world of Project Enzo. They are represented by the intimidating Overlords.
Rule 1: Overlords are the masters!
Primarily set in the underground mine world, the Overlords are the rulers whilst Enzo and his species are slaves. The Overlords are fond of valuable ore that are found in the mines, the feeling of superiority and dishing out unnecessary punishment to the slaves for their own amusement.
Rule 2: Overlords are happy as long as they get richer
These themes are already in place and make the world seen in the animation. It is this group of themes that will become obsolete by the end of the animation thanks to a simple frienship between a bird and a slave name Enzo.
