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 were to take his mask off, the Sith Lord would soon suffocate. So it's the most crucial part of his armor. The only time he can breathe without the need for his mask is when he is in one of his meditation chambers seen in A New Hope.
Jokes aside, it is not his breathing that your hear it is his support system working. George Lucas used various items likes pumps, fans and moving metal compartments sounds while building the Darth Vader character.
How long could Darth Vader live without mask? 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.
Darth Vader's Suit Embeds Needles In His Skin
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.
Lord Vader was able to chew food, which he could consume while in his meditation chamber. While in the chamber, Vader could remove his helmet and consume regular food, which he preferred. Consuming food orally was the way he preferred eating.
However, both Darth Sidious and Darth Vader demonstrated the ability to choke at least two separate individuals simultaneously in relatively casual situations.
Vader was always in dire need of his suit; that said, he needed it to fall asleep (especially his breathing mechanism) if he wanted to take a quick nap. When Vader did sleep, he was awoken soon after by a disturbing series of visions, sounds and pain, most of which including Obi-Wan or Padme.
To escape the armor's claustrophobic nature, Vader had several pressurized meditation chambers built where he could remove his mask and suit and still survive. Vader longed to be less dependent on his armor and tried at times to function without it, but he labored in vain.
Why did Kylo Ren have a helmet? Ren's helmet was a symbolic reminder of his lineage as Darth Vader's grandson, serving no practical use in his life. Ren's helmet was designed to emulate that of his grandfather, the Sith Lord Darth Vader.
By far, Skywalker's most infamous use of it was upon learning of the death of his wife, Padmé Amidala, after his transformation into Darth Vader. This caused him to involuntarily unleash a powerful Force scream of shame, rage, and grief, severely damaging the medical chamber and the droids within it.
It's obvious that Vader requires his suit to survive, but what functions does the suit have, and in what ways does it keep him alive? The helmet is the most important part of his suit. The most apparent purpose it serves is to help Vader breathe, but it's far more complex than that.
The main story of Vader Immortal only lasts about 30-45 minutes, depending on how quickly you move through it. After you complete the story, there is little reason to return to it other than to relive the same story again.
His armor could be hacked and controlled by a device. In a turn of events, Darth Vader's right limb holding his dangerous scarlet lightsaber was moving of its own accord toward his neck. This was a dangerous weakness indeed.
How does Darth Vader sleeps? No. He takes it off in his pressurized meditation chamber, and according to the novelization of revenge of the Sith, he can go several days to weeks with no sleep and rely on mediation and the force to sustain him.
1/15 Luke Skywalker
Having faced his father once before, Luke was familiar with his tactics and used the force to gain an upper-hand. In Star Wars Canon, only Luke Skywalker can be acknowledged as the one who truly defeated Darth Vader.
Appealing to the hate and conflict within him, Darth Sidious goaded Luke into attacking. Vader defended the Emperor and he and Luke were locked in mortal combat. Luke lost control of his anger, viciously attacking Vader, finally beating him down and chopping off his hand with his lightsaber.
Upon learning that Vader was a servant of the Emperor, the look-alike, who was actually Amidala's former Handmaiden Sabé, fired her blaster at the Sith. Vader deflected the laser with the Force and pulled the blaster out of Sabé's hands.
Apparently, he had borderline personality disorder. As he came of age, Skywalker showed problems with impulsivity, violent outburst, illusions of invincibility and crises of identity, all of which are in line with borderline personality disorder diagnosis, the researchers concluded.
Darth Vader's greatest power is not in his ability to hurl heavy objects at Luke Skywalker with the force. His power lies in his unquestioning belief that he deserves to be the leader. That kind of power inspires people to follow, and it is a big part of what makes Vader so irresistible to audiences.
This game features strong violence, involving both human-like and robotic enemies. Characters can be attacked using laser weapons and lightsabers. When attacked, human-like characters groan in pain and fall to the ground.
