Technology & Combat Characteristics
An anthropomorphic bear with a red knapsack unit on its back, the GPB-04B Beargguy is a customized Gunpla of the MSM-04 Acguy. Its weaponry consists of a mega particle cannon mounted in its right forearm, two mega particle cannons in the eyes, six tube missile launchers in each arm, six missiles in its knapsack, and a ranged beam weapon known as beam recorder that is stored on the side of the knapsack. The Beargguy's arms can be extended to increase striking distance, and the suit can somehow hold the beam recorder with its paws.
History
The GPB-04B Beargguy was first created as a simple redecoration – Rina had built a normal Acguy and placed a bear hoodie over its head, and placed a plastic fish in its claws. Haru and Kenta later helped in modifying the Acguy model kit into an actual Beargguy. Rina, along with Kenta in his white Sazabi, was forced to launch without Haru in the Gunpla Battlers Championship, where she found out her Beargguy was not meant for space combat, making her a liability. The Beargguy and Sazabi were rescued from the reappearance of the Hi-Nu Gundam by Haru and the completed Beginning 30 Gundam. When Boris Schauer and his assistants, Diana Lee and Sam, arrive to challenge Haru and his friends, Rina challenges Diana and her MS-18E Kämpfer. Her unconventional weaponry takes Diana off guard as the Beargguy's Mega Particle Cannon (Eye) nearly destroys the Kampfer.
