Mamushi seems to favour close and mid-range combat, fighting with a long snake he has hidden in his sleeve.

In Naruto's Footsteps: The Friends' Paths
Mamushi and team entered the joint Chūnin Exams held by both Sunagakure and Konohagakure two years after the assassination of the Fourth Kazekage. Her team passed the first exam and successfully qualified for the second exam held within Sunagakure. On the third day of the second exam, with the goal of having to pass by obtaining an Earth and Heaven scroll from an enemy team, Saya and her team found Team Asuma. Finding a liking in Sakura Haruno and Ino Yamanaka's appearance, she decided to take them on personally, leaving the less-desirable Chōji Akimichi to him and Sana. As the battle wages, a giant Chōji restrains both him and Sana, but they are soon freed from the Konoha-nin's grasp by Saya who turned her technique onto Chōji after leaving Ino's body.

Ultimately, Ino succeeds in repelling Sana from Chōji's mind, to which the large ninja quickly counters and attacks the Suna team, forcing them to retreat. After regrouping, a hysterical Saya demands to take revenge on Team Asuma for the recent humiliation. Sana then producing a sandstorm to keep enemy ninjas at bay while Saya unleashes a swarm of sand puppets to attack them. Sana also masks Mamushi with sand for an additional sneak attack. Despite this effort, Sakura emerges through the sand and defeats the Suna team with a single punch.
