Flash-Man is the third sequel to Go Rangers, an American remake of Himitsu Sentai Goranger. It follows Dyna-Man and Beast Force and is an adaptation of Chousinsei Flashman. The series was followed by Sky Force.
Many years ago, two astronauts brought their five children on a mission to the flash star system, known for its prism-like formation. The two astronauts were then captured by the evil Experimental Reconstructive Science Empire. Before the children could be also captured, the Flash Defense Army intervened and drove the Empire off. The Flash People then raised the children, before it was discovered that due to their exposure to both Earth's and the Flash system's atmosphere's, the children shared a special aura. The children were trained to become great warriors in order to take advantage of the aura. Many years later, the children's robot guardian Cicuit learns that the Experimental Reconstructive Science Empire is moving towards Earth. The five are dispatched there in order to save their home planet from the Empire, codenamed Mess on Earth, as the Flash-Men. However, things are more complicated than that; the group begins to suffer from Anti-Flash phenomenon.

Experimental Reconstructive Science Empire Mess
Dark Science Emperor Lars Daeus: His origins are unknown. He is imprisoned in a mirror that is kept on board the Mess base. Later, Doctor Blood smashed the mirror in a rage. The pieces recollected and formed a new physical form. He then set about collecting the pieces of a shattered mask which could restore his power. Just as he retrives the final piece, Blood blasts him with his sceptre. The pieces then come together and transform Daeus into a more powerful form. He imprisons Blood and forbids Leoparda from speaking to him. Later, she frees Blood and he plays his organ one final time, transporting Daeus outside where he battles the Flash-Men. He uses his dark aura to transport the Flash-Men into a nightmare dimension. There, they use their aura to blast Daeus, transporting them back, but Daeus absorbs the energy and grows into a gigantic monstrous form. The Flash-Men battle him in their robot and split his mask, severly weakening him before the final blow completley destroys him. Voiced by Ron Pearlman.
Great Doctor Blood: Originally from Earth thousands of years ago, abducted by Mess on their first recon mission to Earth. He was one eight Great Doctors. He joined Mess with the promise of killing the other Great Doctors and absorbing their knowledge. He later had a love affair with Leoparda and they plotted to overthrow Emperor Daeus. She freed him when Daeus imprisoned him. When the base began to explode around them, Blood transported Daeus away to fight the Flash-Men while he died in the explosion.
