They were originally led by Darth Maul (who claimed to be the one chosen to seek out Revan's descendant) until he "stepped down" when he took
It would require something pretty serious for Ezra Bridger to turn to the Dark Side. He avoided it when he was directly offered the chance by both Maul and Emperor Palpatine on separate occasions. He avoided it when he had the chance to save Kanan after watching him die.
In the Star Wars universe, Ezra is a 15-year old orphaned street urchin, scavenger/salvager and con artist who joins the crew of the Ghost in freeing his home planet of Lothal from the tyranny of the Galactic Empire and is taken under the wing of Kanan Jarrus, who trains him in the Jedi arts.
Ezra Bridger, a Force-sensitive human male, was a Jedi Padawan, a freedom fighter, and a revolutionary leader in the early rebellion against the Galactic Empire.
This eventually led Anakin to isolate himself from all who truly cared about him: Obi-Wan, Padmé, and other Jedi Masters, and completely lose sight of reason. Ezra too was enticed by Darth Maul to become his apprentice and was lured into obtaining the Sith Holocron from the Malachor Sith temple.
Rey is Ezra Bridger's Daughter
But that's not to say Del Toro will be playing a new character. I think he's playing an adult Ezra Bridger (from the Rebels TV show). He'd be about the right age, and there have been theories that Rebels will end with Ezra (and Kanan if he's still alive) joining Luke's new Jedi Academy.
We repeat: Ezra is not "A"— nor has he ever been a member of the A-Team. Instead, Aria discovered (while stuck on a chairlift!) that her dearly-beloved beau has been spying on our foursome since the very beginning of the series.
Sometime after Rebels, he returned to Lothal and soon discovered the ancient tomb of Darth Revan. It was from there he soon discovered he was the descendent of the legendary dark lord that he took on his mask, armor and light saber claiming the mantle himself.
Ezra Bridger, the son of Ephraim and Mira Bridger, became part of the early rebellion against the Galactic Empire during the reign of Emperor Palpatine. Strong with the Force, Ezra trained to become a Jedi during his apprenticeship under former Padawan Kanan Jarrus, one of the few surviving members of the Jedi Order.
Yes, Ezra Bridger will be in the upcoming Ahsoka series. Already, Eman Esfandi has been cast as live-action Ezra Bridger, and he's even been spotted (in hologram form) in the first official trailer for Ahsoka.
Maul may have developed a slight fondness for Ezra and still used Ezra to achieve his own goals, it did appear that Maul genuinely wanted Ezra as his apprentice. However, it is made clear by Sam Witwer that Maul does want Ezra as a replacement for his dead brother.
1 Darth Sidious
As well as being a gifted bladesman Sidious' connection to the Dark Side is extremely powerful, granting Sidious the ability to conduct force lightning. Likewise, Sidious took on both Darth Maul and Darth Vader as his apprentice, two of the most powerful Sith and best villains in all of Star Wars.
It soon became clear that Maul was indeed using Ezra and sought to have him as his apprentice, but was thwarted by Ezra's master, Kanan. Despite using him, Maul seemed to have a slight fondness for Ezra, expressing confidence in the boy's abilities and even saving his life twice.
Powers and Abilities
Ezra is one of the most powerful Force users, along with several others, such as the Skywalker family, Rey, and Yoda. He was able to jump long distances when making escapes on the rooftops and sense things before they happened.
For whatever reason in 'World Between Worlds', Palpatine needed Ezra in order to go through a portal; he can't enter it himself.
Ezra Bridger doesn't appear until Star Wars Rebels, which originally started in 5 BBY, so he's also alive at the time of Obi-Wan Kenobi.
One could theorize that he bore a child through some sort of space artificial insemination, or something closer to what we've seen in canon Star Wars material. In the canon comic Darth Vader No. 25, it is revealed that Palpatine somehow used the Force to manipulate midichlorions to impregnate Shmi Skywalker.
In addition to rejecting Sidious, Dathan married a woman named Miramir, whom he fell in love with. Together, they conceived a child, their daughter Rey, who was born in 15 ABY. Although he renounced the Sith Eternal and his donor, the Palpatine bloodline would prosper through him, just as Sidious predicted.
Snoke Was a Strand-Cast Created by Palpatine
Emperor Palpatine created Snoke to be his proxy through which he could regain his power. Although Snoke was bio-engineered in a lab on Exegol, he was a strand-cast, not a clone.
Darth Malak betrays Darth Revan and becomes Dark Lord of the Sith. Force bond forged between Revan and Bastila Shan.
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.
Anakin Marek also known by the names Bane of Vader, The Phoenix Knight, The Ammortal Jedi, The New Revanchist, Wolf of Mandalore, Darth Oryx, First Gray Grandmaster and his public name Ashlo Bogan was a Legendary Force-Sensitve who was the descendant of Revan influenced much of Galactic History and was a Part of all ...
The most prominent example is the Ezra and Aria romance. Ezra was Aria's high school teacher when they started dating — she was only 16 — that alone was creepy.
Aria was afraid to accept the proposal because, as she told Hanna in last night's episode, "I can't promise Ezra forever when my future could be spent behind bars." Which is actually a pretty fair point — she hadn't yet confessed to Ezra that she had accidentally run over Archer/Elliott.
From there, it gets worse when it's revealed that Ezra knew who Aria was when they met at the bar, knew she was underage, and still pursued her for the sake of his book about Alison DiLaurentis (Sasha Pieterse) and her disappearance the year prior.
