Ukaen
Ukaen is the tactican Jakkaen commander who makes Fire Majins from machines. He carries a dragon headed staff and looks like he has a Chinese Dragon wrapped around him. Before the existence of Donkaen and Jokaen was revealed to Rescue Fire, Ukaen was thought to be the top leader of the Jakaens.
History
Ukaen, Sakaen, and Chukaen were awakened when Donkaen was unleashed. The first commander Donkaen sent out was Ukaen. Ukaen made the first Fire Majin, Biken. But he didn't count on the appearance of Rescue Fire. Ukaen then used Revenge Kaen to upgrade Biken. Rescue Fire's Fire-1 and Fire Dragon destroyed the Fire Majin. As punishment, Ukaen was stuffed with ice.
Ukaen had to work together sometimes with the other commanders, usually Sakaen. Another time, he was forced to ask Chukaen for assistance.
Ukaen later had some Jakasts to gain information from Himawari Academy, where he got Tatsuya's (Fire-1) personal information. He created Roboten to scorch down the academy. Then Roboten was transformed into a giant and Ukaen piloted it from the inside. Fire-1 got psyched for Ukaen destroying Himawari Academy and destroyed Roboten with Super Fire Dragon.
After deing defeated by Rescue Fire several times, Ukaen suggested that Donkaen lend some of his own power. Ukaen himself was chosen to have the power. Donkaen warned if he can't control it, the power will destroy him. Ukaen tested out his powers that includes super fireballs, creating a huge area-wide explosion, and making a giant Katachuen without having to use revenge fire. Although he managed to beat Fire-1, Ukaen couldn't fully control the power so Donkaen forced him to retreat. Donkaen then put the power in Ukaen's dragon staff.
