Colan and Marv Wolfman created several supporting characters for the "Dracula" series. They introduced Blade in "The Tomb of Dracula" #10 (July 1973) and Lilith in "Giant-Size Chillers" #1 (June 1974). Colan became the artist of "Doctor Strange" volume 2 with issue #6 (Feb. 1975) which introduced the Gaea character. A crossover between the two Colan-drawn series occurred in May 1976. In 2010, "Comics Bulletin" ranked Colan's run on "The Tomb of Dracula" fifth on its list of the "Top 10 1970s Marvels". His work on "Doctor Strange" was ranked ninth on the same list. Colan's collaboration with Steve Gerber on the "Howard the Duck" series saw the title character nominated by the "All-Night Party", a fictional political party, as their nominee in the Presidential campaign of 1976, and led to Howard the Duck receiving thousands of write-in votes in the actual election. The Gerber-Colan team created Doctor Bong in "Howard the Duck" #15 (Aug. 1977). Gerber later said to Colan: "There really was almost a telepathic connection there. I would see something in my mind, and that is what you would draw! I've never had that experience with another artist before or since."
