G-Man and Great Man have been missing for months, and the whole city is
wondering what happened to them. But when the G-Brothers return to a world of
giant robots and demon hunters, they barely have a chance to catch their breath
before the real danger begins! The Suntrooper Space Force is called into action,
the Thunderfriends assemble, and the Color Guardians unite as G-Man and Great
Man face their biggest threat yet!
