Voltron
Volume 1: Revelations

In the far future, an interstellar cold war rages as the Earth-based Galactic Union faces off against the vast Drule Supremacy - two star-faring superpowers, each looking for the other's weakness. So when an Earth officer named Hawkins discovers that a mythical, unstoppable war machine might actually be real, he doesn't hesitate to send five maverick pilots on an ultra-secret mission to bring back the legend of Voltron. The journey begins here, as Keith Kogane, Sven Holgersson, Pidge Stoker, Lance McClain and Hunk Garrett arrive on distant Arus, where they meet Allura, princess of the ravaged planet...and unearth the five giant, robotic lions that join together to re-create the metal warrior known as Voltron: Defender of the Universe.
