In the distant future, aliens called Victim destroyed all the worlds of humanity except for Zion. In this desperate time, young boys of the space colonies are sent to GOA to learn how to, and compete for the right to, pilot the fighting machines designated as Ingrids. These child pilots are assisted by EX -- a special power, and by female partners who repair the Ingrids. However, to save humanity, exceptional candidates are needed, and two new students, Zero and Hiead, motivated by their desire to succeed and burning rivalry, may be the human race's last hope...
Touno Hikari, Inamura Airi, Unazuki Nao, Marie Vlaanderan, Tanakura Masao and Izumizaki Nana are six would-be pilots attending the robot training institute in Hokkaido. With the goal of gaining a robot license, the competition is fierce and the training is grueling in all kinds of weather conditions. But amidst the lighthearted teamwork, a great danger approaches Earth, and only the secret mecha Dinagiga and its x-genes-wielding pilots can destroy it! Only one question remains... who will be the pilot?!
In a far and distant future, men and women have become mortal enemies. Each living on seperate planets, an interstellar war is being fought between the two very different peoples. Hibiki, a mere 3rd class worker, finds himself in the middle of a huge space battle, facing the nemesis of mankind: Womankind!
Both series have one male pilot with a female backup worker in a futuristic universe where those cute female helpers fall in love with their pilots. Both males use humanoid robots. In Vandread, Hibiki Tokai fights in Vanguard, and in Candidate for Goddess Zero fights in Ingrid. The animation also looks similar. The stories are not the same but have a similar feel.
