Born in Manila, Philippines, in 1946, Danny learned to draw as a child by copying American comic books and later studied art at the University of Santo Tomas. He was an assistant for the Filipino artist Tony DeZuniga and contributed to numerous Filipino comics, including Ace Publications’ Pilipino Komiks, Hiwaga Komiks and Espesyal Komiks.
Bulanadi moved to the U.S. in 1975, and editor Joe Orlando brought him into DC, where he was an inker for Weird War Tales and Legion of Superheroes. He began working for Marvel in 1980 as the inker of Micronauts and went on to work on numerous other series, including Daredevil, Captain America, Fantastic Four, Quasar and licensed titles such as The Further Adventures of Indiana Jones and Transformers. He was known as a quick and prolific inker and worked for the Big Two from the 1970s to the 1990s.
In 1979, at the behest of the owner of the Newfoundland television station NTV, Bulanadi and Scott Stirling created the character Captain Newfoundland. The character first appeared in an eponymous comic strip in the Newfoundland Herald and then in the graphic novel Atlantis and the 1980 made-for-TV movie Captain Newfoundland and the Tip of Atlantis.
In the late 1980s, Bulanadi went to work in animation and was a storyboard artist for Hanna-Barbera’s Jonny Quest and Marvel Productions’ Transformers.
Bulanadi’s other work includes a comics adaptation of the Bible for No Greater Joy Ministries.
Outside of comics, he was a talented painter and draftsman as well as a singer, performing Filipino love songs under the stage name Danny Harana.
