Impulse GM (Mahiru Specification)

Model Number: ZGMF-X56S/gmb

Used by Mahiru in the 14th Gunpla Battle Japanese U-19 Championship, the Impulse GM (Mahiru Specification) is one of two modified ZGMF-X56S Impulse Gundam Gunpla utilized by the Song Dynasty Vase Team. The other Gunpla in the team is the Impulse GM wktk Custom. Both Impulse GM units lack the original Impulse Gundam's Core Splendor or modular body design but share the same basic structure, with differences in the head and backpack design.

The Impulse GM (Mahiru Specification) features a GX-Bit type head and a backpack equipped with small rectangular thrusters and a downward-pointing fin. While both Impulse GM Gunpla use similar handheld weapons, the designs vary slightly. A unique feature of both units is their ability to detach their backpacks and combine them with their handheld weapons to form a large flying mecha called "The Northern Pod," which can be used to ram enemy Gunpla, providing crucial support for the YMS-15KRT02 Gyancelot in battle.
