Hesman or full name "Hero Hesman" (Vietnamese: Dũng sĩ Hesman) is a Vietnamese science-fiction comic series created by artist Nguyễn Hùng Lân from 1992 to 1996. The series consists of 159 volumes with 72 pages each volume, and was published by Hanoi Fine Arts Publishing House.
Hesman originally is an adaptation of Voltron, a Japanese cartoon television series with first 4 volumes based on that cartoon. The next 155 volumes of the series are Hùng Lân's own composition with many events and tens of characters were created. Along the storyline, Hùng Lân added many elements of the real robot genre such as energy sources for Hesman to function or upgrades that alter Hesman's appearance substantially and his status as a cognitive robot. If Voltron is merely a machine, Hesman grew out of this archetype and has been given a personality, which can be described as serious but occasionally displays cunning and a sense of humor. On the other hand, fantastical elements such as magic, wizards and ghosts were also recurrent.
Hesman details an adventure of an intelligent and partially autonomous robot and its human companions. Throughout the series, Hesman and the team travel the Galaxy, fight against various antagonists to defend the universe's peace[1].
