A new trailer for HBO’s Watchmen show revealed at San Diego Comic Con 2019 reveals what appears to be the return of the all-powerful Doctor Manhattan.
As comic readers will remember, Doctor Manhattan departed at the end of Watchmen to further explore his powers and the nature of existence. The trailer’s stinger shows a suited figure reaching down to pick up a blue mask — and a glimpse of his blue hand seems to confirms his return. Even though Doctor Manhattan had left Earth, the trailer includes lots of imagery evoking the character, including a festival with costumes and masks in his likeness, so his impact on the world is still very much visible. He’s as close as the world has ever had to a god living among them, after all.
