Mobile Suit Gundam: The Origin omnibus 1 features story and art by Yoshikazu Yasuhiko and Yoshiyuki Tomino.

It is the year Universal Century 0079. The Earth Federation is storing and testing a new piloted robot for use in the battle against the Principality of Zeon in a space colony. The experimental RX-78 Gundam mobile suit is scheduled to be transported to Federation command in Jaburo, deep within the Brazilian jungles. Unfortunately, before the transporter arrives the Federation is attacked. With few resources available against the Zeon's most mobile mechs, Federation forces strike back using their new weapon, the mobile suit Gundam.

Caught in the crossfire is a young teen named Amuro Ray. Not willing to see innocent people die, Amuro crawls into the cockpit of the closest machine: a Gundam. Having never operated a machine like this, what are the chances he can do anything to repel an experienced squad of mech-piloting invaders?
