Luke told C-3PO he would be right along, but first lit fire to the armor in the hopes that the mistakes of Darth Vader would be shed and that the name of Anakin Skywalker would become a light to guide the new Jedi for generations.
And despite Vader's weaknesses, it's not as if Luke was unskilled, as he spent plenty of time honing his connection to the Force after Star Wars: The Empire Strikes Back, and was likely the most skilled lightsaber-wielder Vader had faced in a long time.
When Vader found Obi-Wan hiding on his ship on the planet Mustafar, he believed his wife had betrayed him, and he strangled her into unconsciousness. He then dueled with Obi-Wan, who dismembered him and left him burning to death near a lava flow.
Sidious' lightning had disrupted most of the mechanisms in Vader's biomorphic suit. Luke was lucky he could gather enough energy to move his father at all. Yet, even still, he managed to get Anakin's body away from the Death Star before it blew up. Arguably by sheer force of will.
He was so clouded by the dark side and Palpatine's lies that he unknowingly walked away from his own family. To confirm that Vader had no clue during the trench run, the moment he finds out about his son is actually revealed in a comic.
Ricocheted away from the Death Star and spun out of control, Vader was unable to stop Luke. The space station was destroyed, but Vader survived, and he flew into the far reaches of space. After the destruction of the Death Star, Darth Vader became obsessed with finding Luke Skywalker.
Many fans declare that Luke won the confrontation because he nearly killed Vader, but that's technically not true. Vader was far more powerful than Luke and easily could have bested him. So, knowing that Vader wasn't allowed to kill Luke drastically changes the equation.
Even after his brutal scorching in the fires of Mustafar, sand remained the only natural phenomenon that Vader feared. To him, sand was a reminder that he'd failed to save his mother or Padme from death.
The realistic answer seems to be, yes, Anakin in his prime could have defeated Luke Skywalker (in the current canon) if they battled one-on-one. The main reason behind this is Luke's lack of formal Jedi training, at least when it comes to combat.
Who would win: Darth Vader at his most powerful or Luke Skywalker at his most powerful? Probably Luke. At the end of the day, Darth Vader never could have destroyed his son. In Canon, following the discovery of his parenthood, Vader became emotionally conflicted.
There are few reasons for this; firstly, the young Skywalker has become more powerful. While he didn't continue his traditional training with Master Yoda, Luke was on the field, practicing what he knew thus far, and honing his skills in the real world.
Darth Vader didn't learn he had a daughter until Return of the Jedi, when he stood before Emperor Palpatine. The Emperor's power probed Luke's mind, attempting to goad him to fall to the dark side, and he discovered Leia's existence. "Sister," the Emperor taunted.
It was the fact that Luke was his son that caused turmoil within Vader. It was his love for his son that caused his loyalty to Palpatine and the Dark Side to falter. If Vader didn't know who Luke was he would have been just another force sensitive person to be trained to serve Palpatine like an Inquisitor or be killed.
Yoda. Yoda's knowledge of Luke Skywalker's true parentage was also confirmed in Return of the Jedi. As with Obi-Wan, Yoda believed that Anakin's fall to the dark side made him unsalvageable, with the Darth Vader persona being his only identity following his ascension to Sith Lordship.
Owen and Beru Lars knew that Luke was Anakin Skywalker's son, but were not officially aware that Anakin and Vader were the same person. The Emperor did know that Anakin and Vader were the same person, but was not aware that any children had survived Padme's death.
according to the legends era. comic story sandstorm, Owen and Peru wanted to honor luke's grandmother, Shmi Skywalker. shmi was a beloved family member to both Owen and Beru, and although they knew of anakin's fate, they saw the positive elements of the Skywalker name. through Shmi, allowing Luke to keep his surname.
Kylo Ren's obsession with Vader is clear, but Star Wars never explained how he acquired the helmet. It is speculated that he may have found it himself on Endor, or it could have been passed down to him by Supreme Leader Snoke.
