With Darth Maul facing Qui-Gon and Obi-Wan at the same time, he was able to defend against both at once. But as soon as he managed to separate the two, Maul was able to overwhelm Qui-Gon and strike him down. That should've sealed the fight for Darth Maul, yet, in the end, he was cut in half by Obi-Wan.
Because Maul punched him with the hilt of his saber and then stabs him faster than Qui-Gon can pull back his blade. So Qui-Gon lost because Maul was physically stronger and quicker than him.
Quite simply, Qui-Gon did not have much training when it came to trying to combat Sith Lords, and at the time, it would have been irresponsible for the Jedi Counsel to spend any additional time concerning a threat that was considered long extinct, especially when you add to the fact that they believed they would be ...
Darth Sidious, was in the earliest stages of his plan to take over the galaxy, and he was afraid a certain Jedi might get in his way. Interestingly, however, that Jedi wasn't Yoda or Master Windu, but instead Qui-Gon Jinn.
Why Did Darth Maul Lose to Obi-Wan Kenobi in The Phantom Menace? - Star Wars Explained
Could Maul beat Vader?
The duel. Darth Vader defeats Darth Maul. The two Sith Lords engaged in a lightsaber duel, going through the volcano and onto a bridge situated over a river of lava, which collapsed, though they both survived and continued their battle.
Overall, Dooku was far more equipped to become a Sith Master than Maul was. Had he managed to overthrow Palpatine, Dooku would have been able to use his position, combat abilities, and dark side Force powers to take his place on the throne Palpatine had carved.
Looking at the tale of the tape: Kylo had more Force-potential, while Kenobi was the better combatant, and their respective motivation tactics were both successful.
After Jinn was mortally wounded, Obi-Wan Kenobi used it to defeat Darth Maul. The weapon would become the temporary lightsaber of Kenobi until 28 BBY when he constructed a second lightsaber identical to his first one that had been lost in the duel with Maul.
He'd put up a fight, but it'd ultimately fail. Kenobi was the most skilled defensive duelist in the Order, specializing in Soresu. This would last him some time, but as much as I love Kenobi, Sidious would be more than able to break his defenses.
When Qui-Gon was killed by Darth Maul, Dooku was so saddened that Qui-Gon's death lead to Dooku's transformation into the Sith Lord Darth Tyranus. He would later provoke the memory against Obi-Wan Kenobi, Jinn's apprentice.
Obi-Wan is good at letting his emotions go. He feels them in the moment, the anger and sadness over deaths of ones he loved like Qui-Gon and Satine. The guilt and pain over Anakin's turn. He feels them deeply, and then lets them go.
Ren was good but Rey was able to beat him every time they fought. However, he wasn't even fully trained and even he would have had a massive problem fighting Maul. Even in his older age, Maul was still way more skilled than anyone Rey faced and that would be the end for her. Maul would just be too much for Rey.
Kylo lost to Rey in TFA because he was heavily wounded and was holding back against her due to Snoke's request that he bring her back to him alive. He is also stated by Palpatine in the Secrets of the Sith book to be “equally as powerful as a real Sith despite not being one”.
The real reason for Obi-Wan's victory, though, may have been that he was the better fighter. While Darth Maul's moves were flashy, Obi-Wan eventually proved himself as one of the best duelists in the galaxy, and his fight with Maul was just the awakening of his skills.
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.
In a non-canon story from the pages of Star Wars Tales #9, Darth Maul was resurrected to fight Darth Vader to the death. Ultimately, Darth Vader was named the victor for a pitch-black reason: He hates himself more. In the main Star Wars canon, Darth Vader and Darth Maul never met, let alone fought.
Yoda struck the Podium too hard to control his landing, and he rolled off the main portion to the edge where he desperately attempted to climb back up. His hold on the smooth edge failing, Yoda lost his grip and fell several stories to the floor. Yoda chose to retreat as Sidious cackled in triumph above him.
You can also see how much Qui Gon Jinn's death affected Dooku when he was talking to Obi Wan in AOTC. Look at the raw, pure emotion Dooku feels over a decade after Qui-Gon died. It affected him significantly.
Though Yoda and Qui-Gon respected each other, they were often at odds due to their differing beliefs; Yoda looked to the future while Qui-Gon lived in the moment.
