Warning: This article contains SPOILERS for Boruto: Two Blue Vortex #4While Boruto's return to Konoha Village was brief, it was enough to show that he is perhaps the most powerful shinobi in Konoha. It's a surprising upgrade to his abilities, even considering the three-year time skip. After a similar period of training in isolation, his father, Naruto, was greatly improved but not nearly as impressive as his son. The difference in powerups may just come down to mentors.
