The GNR-101A GN Archer is a transformable mobile suit developed in the Celestial Being's Lagrange 3 factory as a support unit for the GN-007 Arios Gundam. It was developed with the concept of being an enhanced version of the Tail Booster equipped by the GN-003 Gundam Kyrios during the final battle with the UN Forces. When the GN Archer is in its Flight Form, it can attach to the rear of Arios Gundam's Flight Form, creating the GN-007+GNR-101A Archer Arios. In Archer Arios form, the GN Archer enhances the armament, mobility, and thrust of Arios' Flight Form, like what the Tail Booster did for the Kyrios. Unlike the Tail Booster, the GN Archer was designed to be piloted, enabling it to fight independently and to transform into its Mobile Suit Form (MS Form). However, it is not necessary for the GN Archer to be piloted when in the Archer Arios form, as the Arios' pilot can control this form entirely by himself.
