Which Marvel character did John Romita Sr. create?

American comic artist, John Romita Sr. joined Marvel and started drawing Daredevil comics in 1965. When Spider-Man artist and co-creator, Steve Ditko left Marvel in 1966, Romita was chosen by Stan Lee as the new artist for The Amazing Spider-Man title.
