4: Mace Windu
Before he gave the title to Master Yoda, Mace Windu was the Master of the Jedi Order. He was one of the best lightsaber experts ever. He even made the seventh type of lightsaber battle, called Vaapad. You should mark that he was the only specialist of this battling style that never, ever tumbled to the dark side. He murdered JangoFett, the amazing bounty hunter and was an incredible general. He was thought to be the best Jedi lightsaber duellist that ever lived.
His notable purple lightsaber was shaded by a rare stone that gave it that shading. The powerful Sith Lord Count Dooku escaped from Mace Windu. This was after Mace duelled against him and won. Furthermore, Kit Fisto was with Mace Windu on his last night when they went to capture Darth Sidious and Sidious executed Kit Fisto, dueling Mace Windu after that. When Mace Windu had practically won, Anakin Skywalker deceived him, and the Great Jedi Master died by foul play.
3: Revan
Perceived by the Jedi Order as a stunning military strategist, Revanis, to a great degree, charming and powerful. He was the perfect case Jedi: a legend and a champion. The Mandalorians, a race of amazingly tough warriors, called him the Butcher.
Revan was an awesome Sith Lord. However, the Jedi Order caught him and cleaned his memory, so they could utilize this imposing warrior for their own particular cause. This was something the Jedis had never done and showcases the respect they had for Revan.
Revan went gaga for Bastilla, and together they confronted Revan’s apprentice, the new Sith Lord Malak. Revan attacked innumerable Sith bases, butchered vast quantities of Sith troopers, and murdered many Sith Apprentices and Masters until at last he executed Darth Brandon, who was Malak’s apprentice.
Darth Malak caught Bastilla and changed her over to the dark side of the Force. However, Revan wouldn’t abandon love. He duelled against her and defeated her. She then requested that he should swing to the dark side with her and accept his actual character. Raven refused to do that and went ahead to murder Malak. Bastilla recovered her feelings for love and battled by the Republic too. Later on, Revan was pronounced a Hero of the Republic.
