Above all, Darth Vader's mask enables him to breathe through a series of devices. If he took his mask off, Vader would rapidly suffocate and die. Additionally, all its other enhancements would fail, compromising many if not all his primary senses.
One reason Darth Vader could speak with Anakin's voice was that he could talk without the mask. In Return of the Jedi, Darth Vader, redeemed as Anakin, was able to have a short conversation with Luke before dying on the second Death Star.
If he hadn't been placed in his new armour and had been left on Mustafar by the Emperor who was disappointed with his failure to kill Obi-wan then he would have died. If he had won the battle then his force powers would only grow and it is estimated that he would be about twice as powerful as Palpatine.
Inside his suit and mask, Vader has a series of needles in his skin. Unfortunately, these needles, which transmit neurological data throughout his body and allow him to control his limbs, also cause him constant pain.
And while the suit did keep him alive, it also hindered Vader's abilities and potential as a Force-user. But unknown to Palpatine, this decision would result in his demise. Darth Vader was still undoubtedly powerful, and the suit made him more intimidating than Anakin could ever be. But the suit also limited his power.
What If Yoda TURNED Darth Vader Back To Anakin Skywalker
Can Vader survive without his suit?
While the suit was necessary to save Vader's life after Mustafar, Lucas makes it clear that, in his mind, after a brief period, he could have survived without it. Of course, he wouldn't be the physical presence he is in the suit, which doesn't work for someone so enthralled and held captive by the Dark Side.
Later, however, he jumped into the void willingly. Because of the large amount of mass the overall armor contained (the shoulder armor alone weighed 12.2 kg), Vader did not often run, but was still capable of doing so if necessary.
While the former Jedi Knight's aversion to sand has been a running joke to Star Wars fans for years, Star Wars: Darth Vader #26 added a tragic new dimension to Vader's hatred of seemingly harmless mineral particles by tying it to the all-consuming fear of loss that led him down the path of the Dark Side.
It provides lenses to accommodate his weakened eyesight, pumps air to his body to regulate his temperature, and enables him to speak after his vocal cords were damaged, which explains why he communicates in such a mechanical tone.
The apparatus of Vader's mask was designed to support his breathing. The armor's boots featured magnetic clamps, which could magnetically adhere the suit to a metallic surface, while the legs were heavily armored and able to withstand at least glancing blows from a lightsaber.
Age and resignation. He's matured in many ways, become more patient and restrained. He learned from his defeat, and years of quiet study and contemplation. He's not always at the front anymore, and with no rules to restrict him, he really has no tension.
The Star Wars timeline revolves around the Battle of Yavin, which serves as a reference point for the events and origins of all characters. Darth Vader spent half of his life as Anakin Skywalker before turning to the Dark Side and dying in Return of the Jedi at the age of 45.
His signature heavy breathing is the result of injuries sustained in his near-death battle with Obi-Wan, and one of the most recognizable sounds in the trilogy. Darth Vader, portrayed by David Prowse in Star Wars, is 6 foot 8 inches (2.03 m) tall.
And it's true that Vader and speed and agility on his side, Thanos basically had everything else on his side. Thanos can also just manipulate time and trap Vader in place, He also could of snapped his fingers way earlier in the fight killing Vader in no time. It looks like Vader couldn't Force a victory.
8 Darth Vader's Armor Was Heavy Enough To Bring Him To His Knees. Darth Vader weighed 120kg (264 lbs), and most of that weight is because of the armor's steel and obsidian components.
But while it was out of character for a traditional Sith Lord, Vader's past as Anakin Skywalker showed that his compassion towards the soldiers he led was a major part of his character.
Darth Vader lost his left arm and both legs when Obi-Wan Kenobi defeated him on Mustafar. Skywalker later dueled his former Jedi Master Obi-Wan Kenobi and lost both legs, as well as his left arm.
As an addendum to what Infantry said: Sidious didn't ask to the med droids to put anesthesia in Anakin on purpose. He wanted him awake in order to feel the pain during the whole procedure, since pain is part of the Sith philosophy of life. Vader being born out of pain was not only metaphorical, but also literal.
Age, his suit and his de-limbing lower his strength, but obviously his pain, anger and hate connect him to the dark side and make him more powerful. It's hard to quantify his power at the end without those dark side variables.
