Conway also helped design the character's distinctive costume. As Conway recalled in 2002, "In the '70s, when I was writing comics at DC and Marvel, I made it a practice to sketch my own ideas for the costumes of new characters—heroes and villains—which I offered to the artists as a crude suggestion representing the image I had in mind. I had done that with the Punisher at Marvel." Conway had drawn a character with a small death's head skull on one breast. Marvel art director John Romita, Sr. took the basic design and blew the skull up to huge size, taking up most of the character's chest. "Amazing Spider-Man" penciller Ross Andru was the first artist to draw the character for publication.
