Princess Chimera

Princess Chimera is the four-tailed princess of the Jashinka Empire and a major antagonist in Kagaku Sentai Dynaman. She is the daughter of Emperor Aton and the older sister of Prince Megiddo, as well as a witch who uses her knowledge of magic to assist the Jashinka in their conquest of Earth.

After Aton's demise, she becomes Empress Chimera and one of the two rulers of the Jashinka Empire alongside Megiddo, serving as the secondary antagonist of the series finale.

History
After Prince Megiddo's repeated failures to defeat the Dynaman, Chimera was summoned to assist in the Jashinka's conquest of the surface of Earth. She initially mocked Megiddo for losing one of his tails against DynaRed and the two were at odds, though they later began to collaborate on plans to defeat the Dynamen.

In one notable incident, after taking her clothes off and going out to bath, Chimera had her clothes stolen by Ryuu Hoshikawa and given to Rei Tachibana. In response, Chimera uses Cactus Evo to torture anyone wearing red clothes until she has her clothes returned to her.

Right before Aton's demise at the hands of the Dark Knight, Chimera was declared by him to be one of the two rulers of the Jashinka Empire alongside Megiddo. Megiddo and Chimera sought to finally complete the Jashinka conquest of Earth, but were driven back by the Dynamen. The two boarded the Grand Gizmo to escape, but the Gizmo was slashed in half by DynaRobo, causing the two to perish in the resulting explosion.

Trivia

 * In the USA Night Flight Parody dub, Chimera was renamed as Lucy and was portrayed as Bernie Tanaka (Emperor Aton)'s niece.
