The Star Wars fan base is notorious for being one of the most devoted fan bases in all of film history. Because of this, there is no shortage of fan art, fan fiction, forums, etc. dedicated to Star Wars. Fans on Quora reimagined the iconic look of Darth Vader, and admittedly, the fan-made designs are pretty cool.
Other-Wordly
This reimagined version of Darth Vader by edsfox is probably the closest to the original version; although, this one looks creepier with the threatening claws and menacing mouth cover. He has a ghoulish aura, which is quite frightening, so if Star Wars were to go in a more "eerie" direction, this Vader would be perfect.
A Star Wars/Marvel Crossover
This Darth Vader by Furio Tedeschi looks like something out of a Marvel movie. He has a suit akin to something Tony Stark would create. No helmet is present on his gray head, revealing his yellow eyes and destructed face. This is actually a great element to this Vader because leaving his face exposed allows the villain to emote through facial expressions, which would have been cool to see.
Alarming and Agile
Riyahd Cassiem created this Vader, which appears to be another close replica to the original Darth Vader. Upon observation, it's reasonable to believe that this suit may have been better for the villain in terms of combat. The original suit is clunky in appearance, and Vader seems inhibited by it at times. This fan-made suit seems to be a lot sleeker, providing more mobility for the Sith Lord.
Villain Chic
This reimagined version of Vader by Jose Arias is a far cry from the original. Despite this, there's no denying that the design is really cool. This is a Sith Lord who slays Jedi in style. The shiny shoulder spikes, the narrow helmet and the lustrous armor are all elements that evoke a sinister but chic look. Additionally, this artist created alternate helmet designs, as shown to the right of the picture, all of which are unique and captivating.
Eyes Front
Here is a transparent Darth Vader helmet by Joshua Cairos, revealing his grayed, scorched skin. Besides that, his helmet and mouth respirator still looks somewhat reminiscent to the original. This Vader has some cool armored shoulder pads to top it all off.
Menacing and Magnificent
There's no denying that this Darth Vader by iVANTO has the cool factor. He's got the long, flowing cape, an intimidating helmet and a sleek suit design. This Darth Vader is truly magnificent and evokes a sense of dominance, royalty and power.
Don't Judge a Villain By Their Armor
This Darth Vader by Nathan McGee is pretty cool, however, he doesn't appear as powerful as the others. He almost looks like an alternate version of a Darth Vader guard. Nevertheless, maybe his unassuming appearance would throw off opponents, giving him an edge in battle.
Cool Can't Beat Iconic
Although the reimagined, fan-made Darth Vaders are all cool, they can't beat the original. Cool can't top iconic, and that is exactly what this Sith Lord is, iconic. Darth Vader is inarguably one of the most recognizable villains in the world. He is an unrivaled classic amongst movie villains, and for this reason, his original design will always be unmatched.
