Udon Ise

is a shinobi of Konohagakure, and the leader of Team 5.

Personality
As a child, Udon was an easy-going and quiet individual. He usually looks very sleepy, and is always seen with a drip of snot hanging from his nose. Udon has stated many times that he loves math, as he is sometimes seen writing math problems during class. As an adult, he is a very collected and straight-forward man who is shown to be keen minded and perceptive. As a teacher, he has a strict but fair teaching style and is not above punishing his students for making mistakes that could have cost them dearly. Overall, his students view him as "cool", and were surprised to hear how awkward he was as a child.

Appearance
Udon has short brown hair and dark eyes. He is characterised by the drip of snot always seen hanging from his nose and his circular glasses. While in the Academy, he wore a simple blue shirt which zipped up the middle, a pair of brown pants, sandals and a pair of goggles to represent his membership in the Konohamaru Ninja Squad. As a genin, he has grown noticeably taller, and wears a black top and blue pants with regular shinobi sandals. Instead of goggles, he now wears the village's forehead protector.

Several years later, Udon has not changed his appearance much. He has stopped wearing the Konohagakure forehead protector. He also dons a pompadour-like haircut. He also wears new rectangular glasses. On active duty, Udon wears his forehead protector and wears a navy blue attire and a Konoha flak jacket with long sleeves and a medium-length hem.

Abilities
During his time at the Academy, Udon considered himself a loser, due to struggling to properly perform the Clone Technique, leading to him failing to graduate several times. Upon becoming a genin, he could collaboratively perform the Bouncy Bouncy Technique with his teammates, but his repeated mess up on missions cause him to label himself as a burden on his team. Fifteen years after the Fourth Shinobi World War, he had become a jōnin who specialised in producing powerful water tendrils from his mucus. He's also very attentive, able to deduce whether others are under the influence of genjutsu and quickly release them.

He was seen with Konohamaru Sarutobi, Moegi Kazamatsuri and Naruto Uzumaki before the start of the Chūnin Exams. Later, he met Temari and Kankurō on unfortunate terms.

While he and his friends began fantasising about becoming chūnin themselves, Shikamaru Nara reminded them that they hadn't even become genin yet. Though dissapointed about what they heard, they were worried about Naruto being left out so Konohamaru stooped to disguising himself as him but he was quickly caught by Neji Hyūga's Byakugan. Neji explained that Naruto would return when he's ready as he dreams of becoming Hokage, something he and his friends accepted.

Kazekage Rescue Mission
In Part II, Udon has already been promoted to a genin with Konohamaru and Moegi under the supervision of Ebisu.

However, the genin were not permitted to engage the Byakuya Gang without aid from a chūnin or higher-ranked shinobi. Following Iwabee's overzealous nature, Metal and Denki joined their team-mate in engaging the thieves, which resulted in Metal getting injured and being hospitalised. Udon scolded Iwabee for his reckless actions and clear disregard of orders. He determined that Iwabee should remain confined to his home until further orders.

Later, it was discovered that Boruto and Sarada went missing, to search for Mitsuki. Udon reported it to the Seventh Hokage. As Udon and his team continued their patrol duties during the lockdown, they bumped into a frantic Yurito. He claimed someone attacked one of the guards in recovery and was rushing to get help, but Udon saw through the lie as Yurito would have sent someone else to report such an act as he was head of the Medical Security. Realising he was found out, Yurito took Denki hostage, only for the genin to escape with a flash bomb. As the team's genin attempted to subdue Yurito, Udon realised that he was under genjutsu. He proceeded to free him. As the man began coming to his senses, a C1 Explosive Clay emerged from his flack jacket, detonating and severely injuring Yurito.

Time Slip Arc

While Boruto, past-Naruto, and Jiraiya battled Urashiki, the Konohamaru Army Corps watched from the bushes, amazed when Naruto managed to knock out the foe with his Rasengan. When the foe however transformed into monstrously powerful being, Udon and his friends decided to go for help. While the higher-ups didn't listen, they found several of Naruto's friends, who quickly agreed to help.

By the time they arrived however, Urashiki was already defeated. The group then escorted their injured friends to the hospital.
