Dongoros

Galactic Merchant Dongoros is an alien merchant who does most of his business with the Galactic Imperial Army Zone and a supporting antagonist in Chikyuu Sentai Fiveman.

He is the one who provides the Zone Army with the Enlarging Beast Gorlin that they use to grow their Galactic Warriors giant and serves as one of Zone's three Galactic Commanders alongside Billion and Doldora.

History
Dongoros was present during Zone's attack on the planet Sidon, where Zone first encountered the Hoshikawa siblings. Later, when Zone attacked the Earth, they faced off against the Hoshikawa siblings again, who had become the Fiveman to fight against them.

At the end of the series, as Zone's flagship Vulgyre is exploding, Dongoros hurriedly attempts to pack all the gold bars and Dolyen bills he can before the ship blows up. He ends up dying when the ship explodes before he can get out, ultimately dying due to his own greed.
