The 忍ノ参 Ninpulse Gundam (忍パルスガンダム Ninparusu Gandamu?) is a mobile suit appearing in the anime series Gundam Build Fighters: GM's Counterattack. Based on the ZGMF-X56S Impulse Gundam, the Gunpla is built and controlled by Nils Nielsen
Following the samurai theme of his previous Gunpla, Nils, who like to use machine with motifs from Japanese culture, used a ninja theme for his latest Gunpla.[2] Fitting its theme, the Ninpulse Gundam has ninja-like mobility and can perform actions undetected by the enemies.[2] Using its higher than normal particle control capabilities, it can also reproduce effects of the techniques used by a ninja, such as shadow stitching (kagenui) and cloning (Bunshin).[2] Details of these moves are unknown as any enemies that saw them are destroyed.[2]

Ninpulse Gundam’s weapons are specialized for close combat, but can also be used for ranged combat when thrown.[2] One of these weapons is a large destructive shuriken formed by the wings on its back.[2] These wings can also wrap around the body for better defensive capabilities, and to achieve an optimal form for stealthy actions.[2] This form also sees the lower part of the Ninpulse Gundam’s elaborate V-fin lowering and covering the twin-eye sensors, revealing a movable mono-eye sensor built into the head
