In Brawl Legends, Naruto Uzumaki is a Jonin from the Village Hidden in the Leaves and is also the Jinchuriki of the Nine-Tailed Fox. He trained Lee Hatake in Sage Jutsu and taught him to use Rasengan. He is the alternative future self of Naruto Uzumaki (BOND) from the Tenkaichi Storm Resurreccion timeline.
Naruto lived virtually the same life as his alternate counterpart, although some events took place that neither alternate Narutos have ever faced. He was born to Minato Namikaze and Kushina Uzumaki. As a teen he trained under Kakashi Hatake alongside Sasuke Uchiha and Sakura Haruno, the latter of whom he later married. He and Sakura bore a single child, Minato, named after the Fourth Hokage.
Brawl Legends: Prologue
In the prologue of Brawl Legends (set three months before the events of Naruto: Raging Storm) Naruto stopped by Ichiraku for some ramen. While he was there, a strange man walked in to eat ramen during Konoha's reconstruction, offering free helpings for that day only. The man turned out to be a superhero from New York City known as Spider-Man, and after saying Naruto's then-catchphrase "Believe it", was challenged to a battle. Spider-Man spawned his Symbiote while Naruto charged a Rasengan. Although it protected him from fatal wounds, the alien costume couldn't stop the Rasengan and sent Spider-Man through a wall where a Shadow Clone of Naruto kicked him from behind. After admitting defeat, Spider-Man spoke with Naruto of his history while the rest of Squad 7 arrived. Soon, Kakashi Hatake assigned Naruto to a sparring match, to which he and Spider-Man soon accepted. After witnessing Sipder-Man's defeat by Kakashi's Lightning Blade, Naruto challenged him by attempting to summon a toad. Once he accidentally summoned a tadpole, Naruto seized the oppotunity by kicking Kakashi while he was distracted. He also unintentionally summoned Gamakichi and ordered him to jump on Kakashi's face for a distraction while he drew some of the Nine-Tails' chakra out. He used a Blazing Rasengan to send Kakashi skyward and was soon challenged by a Curse Sealed Sasuke in his First State. They clashed their Rasengan and Chidori and lost their residual energy from the clash, before clashing again in their regular states. Sasuke left to train while Naruto bid Spider-Man a goodbye before the hero's departure. Naruto met with Kakashi upon the latter's retunr from their skirmish, and continued on to train afterward.
