I’m not sure if it’s new, but Megaton Comics has a website that showcases the characters that have graced the pages of the comic throughout its seven-year existence. It’s a relatively small site, but cool none-the-less! Check it out at www.megatoncomics.com.
A description of Megaton Comics from the website:
Megaton was an independent comic book published from 1981 to 1987, and is remembered mainly because of the artists who began their comic book careers in its pages. Erik Larsen, Rob Liefeld, Angel Medina, Gordon Purcell, Butch Guice, Frank Fosco, Clarke Hawbaker, and Daniel Reed all saw their first or second published work in Megaton. Erik Larsen’s Savage Dragon and Rob Liefeld’s Youngblood both debuted there, prompting Liefeld to later bestow the title “Grandfather of Image Comics” upon Megaton writer/publisher Gary Carlson.
