Darth Maul was believed to be dead in the aftermath of the battle but ultimately survived, emerging a decade after his defeat, during the height of the Clone Wars. Despite learning that his Master took a new apprentice, Darth Tyranus, Maul still believed that he was a Sith Lord.
Thought dead, Darth Maul survived his injuries by focusing on his hatred of Obi-Wan Kenobi, the Jedi who cut him in half. His shattered body was dumped amid the refuse of the junk planet Lotho Minor, where the once deadly warrior fell into madness, staying alive on a diet of vermin.
In short, no. Maul, formally Darth Maul (he left the Sith after being abandoned then bested in combat by Darth Sidious), travelled to Tatoonine in his final days. There he confronted an older Obi Wan Kenobi in the deserts outside Mos Eisley.
Sidious revealed to Maul that he did not intend to kill his former apprentice, as he still had use for Maul; it was Sidious' hope that Maul would lead the Sith to Mother Talzin, Maul's mother and the leader of the Nightsisters, so she could be eliminated as a potential threat to the eventual Sith rule of the galaxy.
Suffice it to say; yes he's dead. Obi Wan got his ass. Technically speaking, TCW is the only product outside of Episodes 1-6 to be both Legends and Canon, at least the first six seasons. Season 7 and everything else that spun off of it (Bad Batch, Rebels, etc) isn't part of the EU, but officially seasons 1-6 are.
Why Darth Maul Died So Easily Against Obi-Wan in Rebels - Star Wars Explained
Who officially killed Darth Maul?
The Phantom Menace
In the film's climax, Maul duels Qui-Gon and his apprentice Obi-Wan Kenobi (Ewan McGregor). He is able to kill Qui-Gon and knock Obi-Wan down a shaft, but Kenobi propels himself out of the pit and uses Qui-Gon's lightsaber to bisect Maul, sending the two parts of his body falling down the shaft.
He regretted it because he had essentially wasted 20 years training him. But since he was an enemy at the time of his death on Tatooine, Sid was glad that he did not have to keep watching his back anymore now that the loose ends were tied off.
It's already been shown in the source material… more than once… that Darth Maul is not on Darth Sidious's level. Every time he dueled Sidious as his apprentice (in Legends) he got easily defeated.
In the now-abandoned Legends continuity, his birth name appeared to be Maul, with the title of "Darth" simply added to it when he was taken on as an apprentice by Darth Sidious.
Maul's Solo cameo directly sets up him working closely with Qi'ra - who he instructs to join him on Dathomir - against Tobias Beckett and his crew, which means against Han Solo.
Why is Darth Maul red and not yellow? Darth Maul was originally born a black-skinned Nightbrother, but was later stripped of his markings and given red-skinned Sith tattoos by Darth Sidious. His eyes were also turned yellow with red rims, either due to his touch of the dark side or the eyes he was born with.
In Clone Wars, it's said that Maul refused to die thanks to his hate for Kenobi and for Sidious and that the Dark Side helped to keep him alive. In order to better explain Darth Maul's Clone Wars return, a fan theory (via Reddit) claims that he was either possessed by or had his soul combined with the Son of Mortis.
After tracking Kenobi to Tatooine, Maul engaged him in a brief Lightsaber duel, which resulted in Maul's demise. Before dying, Maul was comforted with the knowledge that Kenobi was protecting the Chosen One, finding some peace in the idea that the end of the Sith was at hand and that he would be avenged.
Dissecting the short fight, Obi-Wan used the same moves Qui-Gon Jinn did during their battle in The Phantom Menace, tricking Maul into executing the same parry he did before. However, instead of committing the fatal error his master did, Obi-Wan pivoted and hit Maul in the body, killing him.
In the novelization he seems to feel… mild regret, maybe? He didn't expect Maul to die, and this might indicate a degree of respect for his apprentice and his skills; he didn't hold it against Maul that he lost, but honestly believed that the Jedi would be killed, so he might have felt that he underestimated them.
Dooku despises Maul for being a threat to him, and for killing his beloved padawan Qui-Gon, and Maul hated Dooku for being his replacement. They also didn't regard each other as a true Sith: Dooku saw Maul as nothing more than a trained animal and Maul saw Dooku as a Sith pretender.
Yep. Darth Maul didn't really say or show straight up that he "feared" Darth Vader, but he openly stated his belief that he could not defeat Darth Vader without the help of the Jedi, therefore on his own.
And while his warnings don't work, at the very least, it shows that Maul became aware of Anakin and what he would soon become. With the rise of the Empire, it's likely Maul caught on to Vader's existence pretty quickly.
He had killed his master, Qui-Gon Jinn, for which Obi-Wan got his revenge by slicing the Sith in half. But after Maul took yet another person away from him, Obi-Wan absolutely hated Maul. The Jedi Master almost let his rage and anger get the best of him, growing close to the dark side before he rejected it.
