Does that plot sound familiar? Well this series from DC comics was released in 1999 so it's probably just a coincidence. The art is incredibly unique (painted style) and its easy to draw parallels to both its influences (there seems to be a stand in for the gargantuas, mothra, etc). Image comics released this series in a single trade in 2006. It's a fun read. I think the art style might be a bit polarizing, but there were some panels that i thought could be framed.
Of all the non-Godzilla giant monster comics i've picked up over the years, i think this would be pretty close to the top of my recommendations list
Comic fans may know Brereton from 'Batman: Thrillkiller' or his creator owned series 'Nocturnals'. Godzilla fans may recognize him as the artist for CVR A of "Godzilla: Gansters and Goliaths #3"
