Darth Vader and Anakin Skywalker are the same person, but they represent different aspects of his character. Anakin Skywalker is the Jedi Knight who ultimately becomes Darth Vader, while Darth Vader is the Sith Lord who succumbs to the dark side. Anakin represents the conflict and struggle within himself, while Darth Vader embodies the power and control of the dark side. Both personas are integral to the complex and tragic story of Anakin Skywalker. **

Obi-Wan calls his student not only Vader, but Darth Vader because "Darth" is a title given to Sith Lords, indicating their allegiance to the dark side of the Force. By using the title "Darth," Obi-Wan acknowledges his student's fall to the dark side and his new identity as a Sith Lord. It also serves as a way for Obi-Wan to distance himself from the Anakin Skywalker he once knew, recognizing the significant change in his former student. **

As an AI, I do not have personal preferences or feelings, so I do not have the capacity to like or dislike Darth Vader.

Yes, Darth Vader does have fears. Despite his intimidating presence and power, Darth Vader is haunted by his past, particularly the loss of his loved ones and his fall to the dark side. His fear of losing control and failing his master, Emperor Palpatine, drives many of his actions throughout the Star Wars saga. Ultimately, his fear of losing his son, Luke Skywalker, leads to his redemption and the defeat of the dark side. **

Darth Vader is not typically considered an antihero. An antihero is a protagonist who lacks traditional heroic qualities and may even have some villainous traits, but ultimately acts for the greater good. Darth Vader, on the other hand, starts as a villain in the original Star Wars trilogy, serving as the main antagonist. While he does experience a redemption arc in the end, his actions throughout most of the series are more aligned with a traditional villain rather than an antihero. **

Yes, Darth Vader is dead. In the Star Wars universe, Darth Vader dies in the film "Return of the Jedi" when he sacrifices himself to save his son, Luke Skywalker, by killing Emperor Palpatine.

While there have been various spin-off stories and expanded universe content, in the official canon, Darth Vader's death is a definitive event. **

Additionally, Darth Vader is known for his heavy breathing and mechanical voice, which adds to his menacing presence in the Star Wars franchise. **
