• Pretty much, their base stats increase by 5% each star.
  not all chars evolve/transform when levling up their star tho.
  
  Most chars which can evolve, only get 1 new form. usually from 1-2 stars.
  but since Naruto & Sasuke is like the mains of the franchise, they evolve 2 times.
  
  all 3 stars chars, c*ually not evolve, they just get increased stats, excluding 1 char.
  Which is Kyuubi Naruto, he can evolve from 3 star. into his 6 tails form, from the Pain Fight.
  
  its atm 3 different Naruto versions in the game, CN got 4.
  1 version of them, can't evolve at all, that is Sage Naruto, well ofc he get increased stats,
  but not a new form.
