Naruto, Episode 17: White Past: Hidden Ambition
Summary of Guruko's Role in the Episode
Guruko, one of the ninken (ninja dogs) summoned by Kakashi, plays a supportive role in this episode, primarily assisting in Zabuza's capture by providing distraction and subduing him through physical force.
Guruko is first introduced when the ground cracks beneath Zabuza, and the ninken start to emerge. Guruko, along with other ninken like Akino, Bisuke, and Pakkun, attacks Zabuza by biting his legs and holding him in place, effectively hindering his mobility. This makes it difficult for Zabuza to escape, and the ninken’s coordinated efforts help to neutralize the danger posed by his superhuman abilities and fearsome weapon.
While Guruko’s role is more about executing the plan laid out by Kakashi, the ninken are integral in clearing up the mist and disabling Zabuza’s ability to fight back. Their sharp sense of smell proves crucial in locating Zabuza, whose own senses are affected by the fog, giving Kakashi the upper hand in the confrontation.
Rating of Guruko's Impact: 4.0/10
While Guruko’s role in the episode is important in terms of assisting Kakashi and defeating Zabuza, his impact is largely passive. The ninken are summoned more for utility and to support the fight against a much stronger opponent than for any personal or notable character development. Guruko’s action is mostly limited to helping in Zabuza's capture.
Given this supportive nature, Guruko's contribution to the episode’s overall progression and narrative is substantial but not highly central, earning him a 4.0/10 for impact.
