GX-34 Gunbuster is presented with a commanding silhouette that highlights Bandai's die-cast craftsmanship. The core frame is built from a gleaming alloy finish and a bold red and white color scheme with yellow accents on the shoulders and knees, faithfully echoing the anime design. The surface shows crisp panel lines, rivets, and subtle weathering to imply battle wear. Large shoulder guards and a robust chest area emphasize the heroic proportions, while the limbs offer sturdy joints for dynamic poses. The arm features a sizable Buster Cannon accessory and multiple interchangeable hands and optional effect parts. The back includes wing-like boosters that can be extended for display. The overall look blends premium metal with durable plastic components for a high-fidelity, museum-grade presentation.

Gunbuster is the flagship mecha of the Aim for the Top story. It is piloted by Noriko Takaya, a determined student who grows from trainee to galaxy defender under intense training and harsh missions. Across the evolving battles, she and her crew confront space monsters and overwhelming odds while upgrading the Gunbuster with new weapons and propulsion. A central theme is time dilation, where long wars on distant fronts feel much shorter to the pilots as time stretches and contracts. The tale emphasizes courage, teamwork, sacrifice, and the cost of protecting humanity. The machine becomes a symbol of hope and resilience as battles span generations and test the limits of human endurance.
