Water Pollution Minister Kegalesia (害水大臣ケガレシア Gaisui Daijin Kegareshia) is the human-looking general with the Kegastick (ケガスティック, Kegasutikku) 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. She fits the theme of a steam-powered water boiler.

When Saki was being imprisoned into 001 by Zontark, Kegalesia helps the Go-Ongers by transforming into Kega Yellow (ケガイエロー, Kega Ierō).



While under the guise of Rena Kegareshi (汚石 冷奈, Kegareshi Rena), 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.

Kegalesia Bomper

While the Go-Ongers were trapped in Samurai World, Kegalesia accidentally separates her Kegalesia Soul (ケガレシアソウル, Kegareshia Sōru) from her body, with her soul set into BOMPER by the other Ministers to convert the robot into Bompelesia (ボンパレシア, Bonpareshia) so they can take advantage 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 Gaiark, 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.

Kegalesia shutdown

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.

A female customer that resemble Kegalesia

In the finale after the defeat of Yogoshimacritein, Saki encountered a female customer that strikingly resemble Kegalesia whose she accidentally 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. After escaping, the three ate sushi from Genta's cart. Tvicon.png TV STORY-Samurai Sentai Shinkenger vs. Go-Onger: GinmakuBang!!


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 the Shinkengers. She (as well as her fellow Ministers) is jailed in Makuu Space under the Zangyack decree that they have chosen peaceful lives instead of causing panic.

Kegalesia was eventually rebuilt along with Kitaneidas and Yogostein by the Ugatz, the ministers deciding to settle down in Junk World and live in peace. However, they accidentally created Noizoon of Eleki Clan Zontark, who creates Grayzky as they force the Ugatz into mass producing their N-chips. The ministers, after Grayzky got taken out by a landmine, help the Go-ongers get back to their world. Kegalesia joins Bearv in getting the other Engines from Machine World, borrowing Saki's Go Phone and Change Soul to aid the powerless Go-o gets by subduing the Noizumi Children-type robot Saki was forcefully converted into. But Kegaleshia is ejected from the Go-on Suit when the extracted Saki crashes into it, remaining on the sidelines as she Souji bring out the Engine Casts so the Engines can combine into Engine-Oh G7 to finish off Noizoon.

Kegalesia is among the vast pantheon of villains which appear in the mobile game Super Sentai Battle Base. She can be either a villain or an ally.
