Ariel (1989)

Overview

In a bid to protect Earth from extraterrestrial invaders and their colossal monsters, Dr. Kishida, like any determined mad scientist, constructs a massive robot—the ultimate feminine warrior! However, his granddaughters are less than enthusiastic about stepping into the pilot seats. They’re too busy with their own lives to take on the role of teenage superheroes, and studying for college entrance exams doesn’t exactly mix well with battling aliens. Now, the fate of the planet hinges on two unlikely heroes: Aya Kishida, the doctor’s granddaughter, who might have to abandon her studies to take control of the magnificent ARIEL, and a mysterious alien called Saber Starblast, who holds the key to defeating the invaders once and for all.
