Udon Ise

is one of the supporting characters of the series. He is a genin-level shinobi of Konohagakure, and together with his friends, Konohamaru and Moegi, he is a member of Team Ebisu, under the tutelage of their jōnin-sensei, Ebisu.

Personality
Udon remains with the same personality and facial expression throughout the series. He appears to be very sleepy, and is always seen with a drip of snot hanging from his nose. Udon states many times that he loves math, as he is sometimes seen writing math problems during class. He idolizes Sasuke, stating that he would be just like him when he gets older. He is rarely seen in the anime or manga, only making a few appearances alongside Konohamaru and his fellow comrade Moegi. His abilities besides the Sexy Techniques, remain a mystery.

Part I
He was seen with Konohamaru and Moegi before the Chunin Exams when Temari and Kankurō were first introduced.

Part II
In Part II, Udon has already been promoted as a genin in a team with Konohamaru and Moegi under the supervision of Ebisu. He was witness to the return of Naruto to Konoha with Jiraiya (and Sakura's subsequent beating him up when he was not shown to have matured from his perverted habits). Called for a mission with his team, he was also troubled when Tsunade mistakenly said that they were going on an S-ranked mission.

Hidan and Kakuzu Arc
In the anime, Udon appears again when Konohamaru was demonstrating his Sexy: Girl on Girl Technique. He witnesses Moegi beat Konohamaru up for creating such a perverted and seemingly useless technique, visibly troubled by his team-mate's injury. In the manga, Sakura is the one to punch Konohamaru.

Invasion of Pain Arc
During the invasion of Pain, he is seen along with Moegi eating at the dango shop when they notice the explosions. He is then seen again along with Moegi and Konohamaru discussing what they can do of Pain's invasion and helping the villagers to evacuate.
