The GPB-X80J Beginning J Gundam is a variant of the GPB-X80 Beginning Gundam featured in Model Suit Gunpla Builders Beginning J. It is piloted by Gunpla builder Takeru Nekki.
Design-wise, the GPB-X80J Beginning J Gundam is more focused on close-ranged combat alone. The overall performance exceeds the Beginning Gundam, but some modification make it more suit for adding external equipment. Its basic armaments remain the same, but is then outfitted with rounded I-Field Armor Plates and the new “Burning J Sword” Long Beam Sword.
