Sargain

Fifth Spear, Sargain is a member of the Seven Darkness Spears of the Jakanja and the right-hand of Tau Zant until Sandaaru shows up. He is a secondary antagonist in Ninpu Sentai Hurricaneger.

Appearing as a giant karakuri-like machine, he is actually a robot piloting by a small mechanical ant. He commands the Jakanja's Mechanin Corps, which is comprised of robots built by himself. Out of all of the Jakanja, he was the one most loyal to Tau Zant.

History
Sargain was tasked with unlocking the power of the Raging Arrow for Tau Zant to use for his plans. He had his monster Gaingain use the Raging Arrow against the Hurricanegers after unlocking its power, though ended up losing it when Gaingain was destroyed.

However, Sandaaru had secretly made a copy of Sargain's data. Seeing no reason to keep him around any longer, on Tau Zant's orders, Sandaaru attacked and killed Sargain.

Sargain was later revived along with the other Darkness Spears by the Evil Will to fight the Hurricanegers and Gouraigers one last time.
