Rank 4: Darth Revan
Revan is a double-edged sword. He was initially a powerful Jedi who was then seduced to the dark side by Darth Vitiate. Revan then founded his own Sith Empire, which became very powerful.
Subsequently, he was betrayed by his apprentice Malak and lost his memory. Revan returned to the light side of the Force and had to learn to deal with both sides within himself. This is very difficult but he managed it because he was very talented in handling the Force.
During his time as a Sith, Revan trained countless students. Many years after his death, Darth Bane found records that ultimately inspired him to establish the Rule of Two. Revan himself went down in history as he founded his own Empire and later helped to destroy it again.
