At the end of each level, one of the super warrior bosses will appear, who needs to be defeated to progress to the next level. The first of them, at the climax of the City stage, is Karnov, who makes a cameo appearance from the Data East game of the same name. Second, at the climax of the Truck stage, is a talon-wielding ninja, Nenail. Third, at the climax of the Sewer stage, is Hanzō, another ninja master, who creates illusions by copying himself. Fourth, at the climax of the Forest stage, is Animal, a behemoth-of-a-man who is also not a ninja. Fifth, at the climax of the Train stage, is Killer Joe, a kusarigama-wielding warrior. Last, at the climax of the Cave stage, is Kon Bōsai, a bōjutsu-master. Finally, the leader of the Dragon Ninja gang, coincidentally also called Dragon Ninja, appears during the climax in his headquarters, where there is a final showdown on a helicopter. The background music during the fight with him is similar to the main theme in "Karnov".
