Getter Robo is made up three jets, known as the Get Machines, that combine into one solitary super robot.
To align in the right formation, a monitor in the Getter Machines' cockpits are shown for the pilot to follow.
A common technique used by Getter Robo is the "Open Get" (オープンゲット) maneuver that causes the Get Machines to detach from each other at flashing speed, not only allowing the Getter to switch forms quickly but to also escape dangerous situations.
In the "Crater Battle" special chapter (prequel to Getter Robo Armageddon) bundled in the Shin Getter Robo manga, the 3 individual Getter Robos had shown the ability to dock with each other and become a powerful cannon turret, with Getter-3 unveiling a firing port from the tip of its Jaguar-Gou, Getter-2 docking above Getter-3 and Getter-1 docking above Getter-2, while also extending energy tubes from its belly into Getter-2 and Getter-3.
The Get Machines (ゲットマシン) are jet-like vehicles that serve as the components to the Getter Robo, they feature a special anti-gravity flight system that allows them to fly for long periods of time and are composed of Getter Alloy, a shape-memory alloy that allow the aircraft to change shape and combine.
It is initially piloted by Dr. Saotome before being passed on to Musashi Tomoe after he joins the Getter Team.
It is able to fly through the cape-like attachment on its back called the Getter Wing that acts as an anti-gravity cloak.
It is more geared toward land and underground combat and it has limited flight capabilities with the boosters on its feet, but it does not work well underwater.
It is coated in a heat resistant apparatus that allows it to travel in magma for a short period of time.
