The entire battle between Palpatine vs Maul and Savage. Probably my favourite lightsaber battle.

Death of Maul in Rebels. After years of searching for his self imposed rival desiring the revenge for all the years of pain he had endured he finds a withered old man who had moved on. Obi-Wan rises to meet his once mortal enemy baiting him with the starting form that his master had used all those years ago. Maul takes the bait and is cut down by the man he had hated for most of his life. In his dying moments he is held and reassured by the same man that the Force, the only thing that Maul had left would be at balance once again. It’s lasts seconds but it’s like a painting in motion with how much is going on

Seen lots of things mentioned already, but I found the absolute power of the Death Star destruction in Rogue One amazing. The Jedha destruction scene is scary like an atom bomb.

Since everyone is saying movies, I’m gonna say the scene before Order 66 in The Clone Wars
