Star Wars has a perfect Jedi, and they are not a legendary movie character like Obi-Wan Kenobi or Yoda. Whereas the original Star Wars trilogy featured only a few Force-sensitive characters, the Star Wars prequels debuted the Jedi Council on the big screen and introduced dozens of new warriors. Most of those died during Order 66, although the list of Jedi who survived the Jedi Purge keeps getting bigger.
Star Wars Rebels, for example, confirmed that at least three Jedi, regardless of the official Jedi designation, fought against the Galactic Empire years before R2-D2 and C-3PO crashed on Tatooine. One of those was Kanan Jarrus, a character created for Rebels but who had experienced the Clone Wars. Like all Jedi who survived Order 66, Kanan had to hide from the Empire and avoid using the Force for years.
