There is also a series of tubes that run through his chest to his lungs and to his burnt-out throat, allowing him to breathe without this advanced system for a brief period should his life support take on severe damage. If he were to take his mask off, the Sith Lord would soon suffocate.
He dies within ten minutes of a near total shutdown of his suit after throwing Lord Sidious down a reactor shaft, and in Episode III, his heart actually stopped during his transformation before his suit's helmet is sealed. At most, I'd say about ten to fifteen minutes.
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.
Why Can't Darth Vader Breathe Without His Mask? Dark Vader cannot breathe without his mask because his mask is connected to a life support system. His famous black armor suit covers this life-sustaining system.
Darth Vader also experimented with Force healing fueled by the dark side, in which meditation on anger and frustration at his life and circumstances allowed his lungs to function without the aid of his hyperbaric chamber or his life support suit.
Darth Vader's Suit Embeds 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. Between the never-ending itchiness and walking around with needles in his skin, it's no wonder he is so angry.
If Vader was able to access his full potential and immerse himself completely in the force, he would have no trouble overthrowing Palpatine... So for that reason, Vader's suit kept him in a constant state of weakness, but also brought his his full range of anger and pain.
If he were to take his mask off, the Sith Lord would soon suffocate. So it's the most crucial part of his armor. He can only breathe without the need for his mask when he is in one of his meditation chambers seen in The Empire Strikes Back.
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.
Vader's suit took care of most of his need, which also included food. The suit feed Vader nutrients, which gave him the energy he needed to continue throughout his days. He also consumed RepMed vita paste through a straw, which was located within the grills of his mask.
Once on Endor, Luke built a funeral pyre and lit the armor on fire, declaring his hope that the name of Anakin Skywalker would be a light to guide the new Jedi.
15 He Can't Sleep
Truth is, he was constantly uncomfortable whenever he was in his suit, to the point that it made him sometimes incredibly insane. Vader needed to take breaks, dipping himself in a liquid chamber where he allowed himself to meditate as we saw in a deleted scene of Rogue One.
When focusing on the main objectives, Vader Immortal: Episode I is about 52 Mins in length. If you're a gamer that strives to see all aspects of the game, you are likely to spend around 3½ Hours to obtain 100% completion.
Weakness: Electricity
It took a single-minded desire to inflict pain upon another individual to transform the Force into such a destructive weapon. Darth Vader possessed the skill to use Force lightning, but the limitations of his suit prevented this.
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.
Darth Vader lost his left arm and both legs when Obi-Wan Kenobi defeated him on Mustafar. After turning to the dark side of the Force, Skywalker severed Mace Windu's right hand to save Darth Sidious when Windu tried to kill the latter.
Eventually, he lost both his legs and his remaining arm in the climactic duel on Mustafar between both he and Obi-Wan. As Vader, he had each limb replaced with cybernetic parts, but would lose his robotic right arm one last time when Luke Skywalker faced his father in Return of the Jedi.
Darth Vader was just 45 years old when he died. He was born on 41 BBY and died on 4 ABY during the Battle of Endor. Darth Vader basically killed himself when he betrayed Emperor Palpatine to save Luke Skywalker. This led to his life-support suit getting damaged by Palpatine's Force Lightning, leading to his death.
Sidious created the suit to keep his apprentice alive, but he also intended to ensure Vader remained loyal to him. Acting primarily as a life support system, Vader's suit keeps him alive, but Sidious ensured it also kept him in pain. Vader constantly experiences excruciating pain due to the suit's design.
Darth Vader's armor, also known as Darth Vader's suit, was a suit of armor worn by the cyborg Sith Lord Darth Vader. Designed with life support technology, the armor ensured Vader's survival following the lightsaber and burn injuries that he sustained in a duel with Jedi Master Obi-Wan Kenobi on Mustafar.
In a Vanity Fair interview from 2005, George Lucas went deeper into why Anakin became much weaker as Vader. In the interview, he explained that because Anakin's limbs were severed and replaced by robotics, it was harder for him to use the Force than it was before his battle with Obi-Wan.
However, most people don't survive if their lungs were damaged beyond repair, which Vader's were, and that is a bit of a sticking point. The rest would be bad but someone could potentially survive.
Purpose. Darth Vader's meditation chamber was a life support pod that allowed the Sith Lord to survive for extended periods without the helmet and mask of his suit. The injuries Vader sustained during his duel against Obi-Wan Kenobi on Mustafar normally made this impossible.
Darth Sidious
In the end, Vader managed to fulfill the prophecy tied to him. As for Darth Sidious, he's by far the most dangerous enemy Vader has had.
