Their creation first appeared in "Pilipino Komiks" in 1979 as the comic serial "Ang Panday". It sold hundreds of thousands copies every week during its run in the 1980s. The first stories do not contain fantastical elements and Panday is just an ordinary blacksmith named Flavio who fights criminals by using his sledgehammer. He has no superpowers and no supernatural weapons. In the later stories, Panday possesses a dagger that turns magically into a sword which he forged from a mystical meteorite. Caparas got the idea of meteorite from his childhood where he and his playmates would find these kind of rocks and when they break them, sparkling materials that seems magical can be seen inside.
