Water Pollution Minister Kegalesia is one of the villains in Engine Sentai Go-onger. She is the human-looking general with the Kegastick who leads the Barbaric Machine Clan Gaiark's Water Barbaric Machine Beasts. She has artificial human-like skin that regenerates and shoots steam from the projections on her back armor if she is in a foul mood. The handle on her head cuts off this leakage. She ends her sentences with "Ojaru", is a heavy drinker who hates to be called "Old Lady", sometimes enlarging from the anger being too much to fume out of her.



While under the guise of Rena Kegareshi, Kegalesia develops a vendetta against Hant Jou, due to his falling in love with her guise and calling her endearing names, like "pure," which are offensive to members of the Gaiark. It was with this taboo that she could never fall in love with Nigorl, as his ideas were the opposite of the Gaiark's.

While the Go-Ongers were trapped in Samurai World, Kegalesia accidentally separates her Kegalesia Soul from her body, with her soul set into BOMPER by the other Ministers to convert the robot into Bompelesia so they can take adventage of the situation by setting a trap. However, Bomper manages to regain control and ejects the Kegalesia Soul prior to being reinstalled back in her body.

She occasionally joined Saki Rouyama and Miu Sutou in the 3-girl idol group G3 Princess, though the second time ended with her enlarging and being knocked into the distance by Engine-O G12.

After Crime Minister Yogoshimacritein arrived to take control of the Gairak, both Keglesia and Air Pollution Minister Kitaneidas became greatly displeased that Yogoshimacritein was treating them as nothing more than pawns, which became worse after he was using them as shields to protect himself from the Go-Ongers' attacks. Eventually as an act of defiance, Kegalesia aided Kitaneidas in destroying Infinite Wastebin, only to be seriously damaged by Yogoshimacritein.

In her last act, she reveals the location of the Deus Haguru Magear where the source of the Gairak's power was 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. Kegalesia and Kitaneidas then shut down as they tried to embrace their hands together one last time.

In the finale after the defeat of Yogoshimacritein, Saki encountered a female customer that strikingly resemble Kegalesia whose she accidently splashed her with strawberry cake. The customer is very angry that Saki dirtied her new coat but decided to forgive Saki because the cake itself is delicious.

Shinkenger vs. Go-Onger

When Pollution President Batcheed attempts to make a deal with the Gedoshu to bring back his ministers to assist in his own plans, Kegalesia (who is now a wandering spirit) wants nothing more to do with him and escapes alongside the other two, where they were last seen wandering along the Sanzu River.


Kelgalesia has appeared in two films tied to Kaizoku Sentai Gokaiger, being the only villain to do so. She appeared along with Saki and Miu in Kaizoku Sentai Gokaiger The Movie: The Flying Ghost Ship as a member of G3 Princess to distract Baseball Mask for a third strike. She then returned with her Gaiark allies in Kaizoku Sentai Gokaiger vs. Space Sheriff Gavan: The Movie, where she is shown to remain a deceased wandering spirit just as previously in the Go-Onger cross-over with Shinkenger. She (as well as her fellow Ministers) is jailed in Makuu Space under the Zangyack decree that they have chosen peaceful lifes instead of causing panic.

Special Attack

Due to her nature as the Water Pollution branch leader, she can execute Water Pollution Fusion (害水合身, Gaisui Gasshin) with any member of the same branch, boosting up their power as a result.

As part of G3 Princess with Go-on Yellow and Silver, she performs Princess Cannonball (プリンセスキャノンボール, Purinsesu Kyanonbōru), after performing G3 Triangle (G3トライアングル, Jī Surī Toraianguru) which passes the ball made by them.


  • Her name is from on the Japanese word for "to get dirty" (汚れる, kegareru).
  • Before entering battle, Kelgalesia says, "The muddied and fetid waters! I am Water Pollution Minister Kegalesia!" (濁り腐った水よ! わらわ、害水大臣ケガレシア, Nigori kutta mizu yo! Warawa, Gaisui Daijin Kegareshia).
    • After transforming into her true form as part of the one-time only G3 Princess idol group, Kelgalesia says, "Love me or regret it!! Kegalesia" (惚れなきゃ後悔!!ケガレシア, Horenakya Kōkai!! Kegareshia).
  • Like her two partners, Kegalesia remains technically dead due to the events of Go-Onger; though appearing in cameos in both Shinkenger and Gokaiger, she remains a wandering spirit.
    • Though appearing as a member of G-3 Princess post-death, this was not physically her but merely a delusion of Baseball Mask brought upon by the attack of the Gokaigers by using the Gorenger Storm.
  • Kegalesia is the most recurring villainess in Super Sentai.
