Kate

"My name is Kate."

"Kate?"

"And I can control mosters."

Kate (ケイト, Keito) is a fictional character from the Ultra Galaxy series. She is a powerful Reionyx and Rei's older sister. She served as Ultra Galaxy Mega Monter Battle's main villain.

Bio
Kate was a Reionyx who tried to interfere with Rei with every possible means. She took on the appearance of a bio-plant researcher named Maki Azursa. She appeared to be evil, but she reviled that she was Rei's sister and was trying to help rewaken Reimon. She was thought to be killed after EX Gomora destroyed her monster Zetton. However in Ultra GalaxyMega Monster Battle Never Ending Odyssey, it is revealed that she survived as she appeared in front of the ZAP SPACY crew first in the Pendragon, in front of Grande and then in front of Rei in a dream in episode 7. She had appeared and explained to the crew what was wrong with Rei once he lost Eleking.

Grande has a crush on her.

It also is unknown how much but it is believed that Kate cared about Rei as much as any older sister would care for their younger brother.

Battlenizer Monsters

 * Fire Golza, a much stronger form compared to his original, Fire Golza was the first monster to appear from Kate's Battlenizer. He first appeared to battle a number of Sadora's and killed them all, but when he was in battle with Gomora, Gomora impaled Golza with his horn, surging his Osillatory Wave through his body. Even though Golza tore the horn out of his body, he still fell and in the end was destroyed by Kates Gan-Q.


 * Gan-Q, a monster that's even more ferocious than Fire Golza, Gan-Q was the second monster commanded by Kate. Gan-Q entered battle with Gomora, Litra, and the Space Pendragon and was defeated by the ship's Hyper Omega Gun.


 * Zetton, the Space Dinosaur himself, Zetton was the third, final, and most powerful monster that belonged to Kate. In episode 12, Zetton entered battle with all of Rei's monsters (Gomora, Litra, and Eleking) and outmatched them all. In the final episode, when Zetton had Gomora in defeat and King Joe Black appeared, fighting Zetton to a standstill, Gomora transformed into EX Gomora and defeated them both, which resulted in Kate's supposed death.
