Published by Blacklist Studios, this comic stars a robot with a skull for a head.
One of 2 covers is shown here.
The author Thomas Hall describes it as follows:
On the surface, the comic is about a skull headed robot who fights giant monsters from Greek Mythology. From a storytelling standpoint, however, it’s somewhat a reworking of Frankenstein meeting Homer’s Odyssey- it’s the story of a thing created by Science who goes on a Hero’s journey of sorts to find out who he really is…
You had me at robots fighting giant monsters such as the octopus shown on the cover. Your copy can be had now for a measly $5.25 ,including shipping, from Blacklist Studios.
