Franco

One of the six cowboys who rode with Rock, a bearded dynamite expert who often smoked a cigar.

During the fight against Hyoh and his private army, he used his dynamite to blow up a passing tank, sowing chaos and confusion among Hyoh's men. He was eventually cornered by a large group of soldiers, but used his last explosives in a suicide attack, taking many of the Rasho's men with him.

trivia: He is most likely modeled and named after the Italian actor Franco Nero.
His love of cigars and dynamite is similar to Jackal. Both characters use a lit cigar to light their dynamite at one point.
