How is Revan related to Anakin? Probably not in any way. The only thing we know about Revan from canon sources is that he was an ancient Sith Lord, who the Sith Eternal named their 3rd Legion after, and nobody else in the modern galaxy had ever heard of him.
I found out that Darth Revan is actually the brother of Cade skywalker, who is Anakin's ancestor and this furthers my belief that if something drastic happens in starwars there's a skywalker around the corner.
SPOILERS for Obi-Wan Kenobi episode 2. Obi-Wan Kenobi episode 2 revealed Reva knew Darth Vader's greatest secret: that he is really Anakin Skywalker.

As impressive as Vader's battle tactics might be, if he and Revan make a stand with comparable armies, Revan is likely to be victorious.
While their stories are similar, Darth Revan went even further than Vader. Whereas Vader bowed to Darth Sidious, Darth Revan was so powerful that he bowed to no one, becoming the sole leader of the Sith. He was able to do what Vader did but even greater.
Revan Skywalker was a Jedi Knight and twin brother of Cade Skywalker. His father was Kol Skywalker and his mother was Morrigan Corde. He was apprenticed to Jedi Master K'Kruhk. To distinguish himself from his older brother Cade, Revan would dye his hair black.
killed by an Imperial strike team, his dark side, like many Seth before him, refused to let go of life.
Though he was first referred to as "the Revanchist Leader" in news reports, the young Jedi Knight soon became known simply as "the Revanchist."
Reva explained that she discovered a connection between Bail and Obi-Wan in the archives. She doesn't realize that Leia is Vader's daughter. Reva does attempt to use the Force to peer into Leia's mind when she kidnaps her again. However, the little princess was able to defend her thoughts.
Reva knows that Anakin Skywalker is Darth Vader because she was one of his targets—a child—during the Order 66 killings that took place during the events of Star Wars Episode III: Revenge of the Sith.

1 Can't Beat: Revan
Both of them have been responsible for the eradication of hundreds of powerful Force-users and both warriors were masters of telekinesis and lightsaber combat. Revan triumphs in this contest mostly through statistics. He was the greatest warrior of his time, while Anakin was not.
Darth Malak betrays Darth Revan and becomes Dark Lord of the Sith. Force bond forged between Revan and Bastila Shan.
Disney used Revan as an inspiration to create Kylo. His armor, inner conflict between Light and Dark and his use of the Force. Snoke considers Kylo to be the ideal embodiment of the Light and Dark sides of the Force, much like Revan, who was a master at both sides of the Force.
Revan has incredible will, which was what allowed him to endure centuries of torture from Vitiate, though he was not unscarred. His mind started to become twisted between the light and dark sides and after his light side left him, Revan was completely fueled by anger and hate.
1 Darth Vitiate
Hands down the greatest Sith of all time, Darth Vitiate was one of the galaxies most feared and dangerous threats. His power was so great that he himself was a danger to every living thing that surrounded him.
Revan was a Sith Lord and the namesake of the Sith Eternal army's 3rd Legion. Since the history of the Sith was kept hidden from the galaxy, only Sith cultists knew the significance of Revan's name.
In his prime, Revan was an unstoppable force on the battlefield, skilled in multiple forms of lightsaber combat, and regarded by many as the greatest warrior of his age. He accumulated respect from a vast range of different cultures from the Mandalorians to the Echani—the Rakata to the ancient Sith.
Although Revan is seen both in-universe and by many Star Wars fans as a living legend, he's ultimately a flawed and in many ways vulnerable character. Reva is introduced in the Obi-Wan Kenobi series as a different sort of Inquisitor than the Star Wars canon continuity has had thus far.
1 Darth Sidious
There has been no Sith, as powerful, meticulous, nor as evil as the Emperor himself, Darth Sidious. As previously mentioned, Sidious trained in the Dark Side by Darth Plagueis before Sidious killed Plagueis in his sleep, making Sidious a Sith Master.
He would go through many twists and turns in his life but it would be defined by his time as a feared Sith Lord. Revan is another Sith who is easily Ren's superior in just about every way. He was an extremely successful combatant and general.
In Star Wars Legends and Canon, Galen Marek (Starkiller) is the only Jedi (other than Obi-Wan Kenobi) to put a beat down on Darth Vader/Anakin Skywalker. Galen was secretly trained as a Sith Lord apprentice to Vader, but returned to the light side and the Jedi.
Revan, specifically during his time as a Sith, would crush Anakin, assuming we're talking about Anakin towards the end of Revenge of the Sith. Anakin was extremely powerful and skilled, but he was still lesser than Sidious at the time.
