Ukon is Sakon of Naruto's brother. He does not have a pearly necklace and seems to be more masculine personality-wise. He is a Chuunin and was born on June the 20 and is currently 14. See Sakon for more information.
Ukon, Kin, and Anko are one of my favourite threesomes.
I wouldn't mind seeing some more Ukon in Naruto.
Ukon is so not dead.
