"Roar and Howl! The Ultimate Tag-Team!" (唸れ!吠えろ!究極のタッグ, Unare! Hoero! Kyūkyoku no Taggu) is episode 120 of the original Naruto anime.


As Tayuya guides her three Doki after Shikamaru, she activates the first level of her cursed seal to control them easier. Naruto begins his battle, creating a great deal of shadow clones to attack Kimimaro, who, however, is able to defeat the clones. As the fight between Kiba and Akamaru vs. Sakon and Ukon rages on, Ukon pushes his cursed seal into its second level. Recognising the huge increase in strength that this allows the brothers, Kiba and Akamaru combine to become a giant double-headed wolf. The combined beast charges towards Sakon and Ukon, and bisects them. However, the brothers' internal organs creates new legs and arms. Kiba and Akamaru charge at them again, though the brothers are able to use Summoning: Rashōmon to block the attack. As the wolf transformation disperses, Akamaru is attacked and left heavily injured, although Akamaru manages to squirt acidic urine into Sakon's eyes. Sakon goes to wash his eyes in the river while Ukon merges himself with Kiba's body. Needing to get rid of Ukon to save Akamaru, Kiba stabs himself in the stomach, causing him and Ukon to start coughing up blood.
