To protect the future of the GGG from the Lost Gear-fused Proto, Mona has created a giant Gunbar! Piloted by G-Wrench, Gunbar fights the Lost Gear. It's giant robot versus giant robot... the biggest battle ever is about to unfold, with the fate of the GGG on the line!
So that someday, we can
fight Grandpa together!
!وذلك كي نتمكّن من مقاتلة جدّي معاً يوماً ما
Damit wir irgendwann
gegen Opa kämpfen können.
Pour nous préparer au jour
où on se battra à ses côtés !
Così che un giorno potremo combattere al suo fianco!
Para que um dia possamos 
lutar juntas contra o vovô!
Чтобы однажды вместе 
сразиться с дедушкой!
