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

The Impulse GM wktk Custom features a GM-type head and a backpack with a large circular thruster and a prominent upward-pointing fin. While both Impulse GM units use similar handheld weapons, the designs differ slightly. A unique feature of both units is that their backpacks can detach and combine with their handheld weapons to form a large flying mecha called "The Northern Pod," which can be used to ram enemy Gunplas in battle, providing support for the YMS-15KRT02 Gyancelot.
