Kegalesia

"The muddied and fetid waters! I am Water Pollution Minister Kegalesia!"

- Kegalesia's catchphrase when he enters into battle.

Water Pollution Minister Kegalesia is one of the three Pollution Ministers of the Banki Clan Gaiark and a major antagonist in Engine Sentai Go-Onger.

Engine Sentai Go-Onger
Kegalesia arrived in the Human World along with Yogostein and Kitaneidas, establishing Hellgailles Palace as their base on Earth.

In a notable incident, while the Go-Ongers were trapped in Samurai World, Kegalesia accidentally separated her Kegalesia Soul from her body and possessed BOMPER, leading to the other Gaiark Ministers using "Bompelesia" to set a trap for the Gaiark. However, Bomper eventually regained control and cast out the Kegalesia Soul from its body.

After Yogostein died and his father Crime Minister Yogoshimacritein arrived to take control of the Gaiark, both Keglesia and Kitaneidas were frequently abused by the Minister and treated as nothing more than pawns. After worse after he was using them as shields to protect himself from the Go-Ongers' attacks. In an act of defiance, Kegalesia and Kitaneidas destroyed Infinite Wastebin, to which Yogoshimacritein responded by fatally injuring both of them.

Right before dying, Kegalesia reveals the location of the Deus Haguru Magear, the source of the Gairak's power, to Sosuke, Renn and Saki. This allowed the three to realize they had to destroy it to save Hanto, Gunpei, Hiroto, Miu and the other Engines. As Kegalesia and Kitaneidas pass away the two try to hold each others hands one final time.

In the finale after the final battle, Saki encountered a female customer with a similar appearance to Kegalesia. After Saki accidentally splashed her with strawberry cake, the customer became angry that Saki dirtied her new coat but forgave her after discovering that the cake tasted good.

Kegalesia was later revived along with Yogostein and Kitaneidas. Pollution President Batcheed attempted to recruit the three back into the Banki Clan Gaiark as they were eating sushi from Genta's cart, but the three didn't want to fight anymore and instead wanted to retire at the bottom of the Sanzu River and get drunk.

Gokaiger vs. Gavan
Kegalesia was among villains imprisoned within the Space Prison in Makuu Space by Makuu Prison Warden Ashurada. Kegalesia and the other villains were later released by the Gokaigers when they caused a big ruckus within the prison.
