A Variable Fighter is one of a series of transforming aerospace fighters primarily designed by Studio Nue's Shoji Kawamori and Kazutake Miyatake for the animated series Macross and later related projects.

Their defining feature is the ability to transform--usually into a humanoid giant robot called Battroid and an in-between mode called GERWALK(Ground Effective Reinforcement of Winged Armament with Locomotive Knee-joint), in which the nose and wings have a pair of "chicken walker" legs extending underneath enabling VTOL, and two arms reaching forward from the sides. Another prevalent (but not universal) design point is the use of a detachable gun pod instead of an internally mounted gun. This allows it to be used as a hand-held weapon in GERWALK and battroid modes. They usually also have one or more trainable head-mounted lasers in battroid mode, stowed internally or used as fixed armament in fighter and GERWALK modes.
