9. Anakin Skywalker Vs. Barriss Offee
In the season five finale of The Clone Wars, "The Wrong Jedi", Anakin's Padawan Ahsoka has been framed for the bombing of the Jedi Temple, and Anakin begins tracking the real culprit.
His search leads him to Barriss Offee, a disillusioned Padawan who has secretly turned against the Jedi.
The resulting battle sees both sides dual-wielding lightsabers, and the swelling classical score makes the scene feel as though it could easily have been part of the movies.
We also get to see Anakin channel his future Sith Lord self, with his attacks becoming increasingly brutal before he pins Offee to a tree and chokes her with the Force.
It's a scene that highlights just how great The Clone Wars was at depicting lightsaber duels, and in many senses, it outshines some of those depicted in the franchise's movies.
