One of the most potent characters in Star Wars, Abeloth was capable of using both the dark and light aspects of the Force. She consequently rose to become the Bringer of Chaos and the Beloved Queen of the Stars.
Recent Star Wars TV programmes have highlighted Darth Vader's strength as one of the most potent figures in the franchise.
One of the most experienced, wisest, and most powerful figures in Star Wars was Yoda. He was in charge of teaching the ways of the force to Count Dooku, Mace Windu, Luke Skywalker, and a number of other Jedi.
One of the most lethal and maniacal Sith masters, Darth Sidious was also the most potent figure in the entire Star Wars universe. Using his two identities, through which he was able to control most events in the galaxy, he brought about the collapse of the Galactic Republic and the Jedi Order.
In order to attain immortality, the master of Darth Sidious used science to manipulate and mutate midi-chlorians. He spent many years collaborating with Sheev Palpatine on their schemes to rule the galaxy for ten thousand years.
Bane, one of the most potent Sith lords ever, was the lone survivor of the annihilation of the Brotherhood of Darkness. He restored the Sith Order and instituted the Rule of Two after realising that the Sith's internal strife had led to their demise.
Former Jedi Master Dooku, also known as Darth Tyranus, converted to the Dark Side. During the Clone Wars, he served as Darth Sidious' apprentice and put forth a lot of effort to carry out his master's schemes.
