The Gundam W package combines the entry-grade Wing Gundam and Build Booster to form the Build Wing Gundam Full Package!!
The Wing Gundam was first used by Sei in the battle with Sasaki in episode 1 of Build Fighters, but was destroyed and then repaired and repainted.
The base Wing Gundam has been painted to resemble the Build Strike Gundam.
Furthermore, combining the Build Wing Gundam with the Build Booster completes the Build Wing Gundam package.
