The RX-178+FXA-05D Super Gundam is the combination of the RX-178 Gundam Mk-II and the FXA-05D G-Defenser. The AEUG developed this combination to give the Mk-II enough mobility and firepower to deal with the Titan’s transformable Mobile Suits. The RX-178 Gundam Mk-II and FXA-05D G-Defenser build separately and will combine once completed. The molds used for the RX-178 Gundam Mk-II are the same as the HGUC Mk-II Titans version which, was released a few months before the combo set.

The RX-178+FXA-05D Super Gundam set includes:

• RX-178 Gundam Mk-II
• FXA-05D G-Defenser
• Long Rifle
• Beam Rifle
• Bazooka
• Vulcan Pod System
