Vein Mask is brought in to gain a special sword obtained by EAGLE that has a massive destructive force that can rip through anything, including solid steel. Using his knowledge of poisons, he attacks the EAGLE agent believed to possess the sword, only to discover alongside the Gorengers that he did not possess it. When he is transported to a hospital, he attacks with a platoon of Zolders disguised as doctors and nurses to draw him out and find out what happened to the weapon. During a battle with the heroes, Kirenger ends up bending his blowgun before firing one of his poison darts, making him get poisoned and run around until he is able to cure himself.
