The reveal comes from Marvel Comics' Darth Vader #9, written by Greg Pak with art by Raffaele Ienco. In the issue, Darth Vader's armor and prosthetic limbs have been Droid Crush Pirates to in the hunt.

However, the crew of droids had only agreed to help Ochi after he promised them that they could take pieces of Vader's armor and machinery once they succeeded in killing him. However, the leader of the pirates soon realizes that their promised prize is no prize at all. After scanning Vader, it's revealed that his armor is nearly 30 years old and is far from the "Emperor's greatest weapon" as d by Ochi. Upon learning this, the lethal and angry droids set their sights on Ochi.

Thankfully for Ochi, Vader has a need for him to decipher a Sith Wayfinder, which motivates the Dark Lord to save the assassin from the pirates' reach. He also regains his lightsaber from the assassin, and promptly eliminates the entire crew with extreme and deadly prejudice. Ironically, their parts work just fine for Vader's needs, as he uses them to repair an abandoned Jedi starfighter from the Clone Wars to escape the planet (which could very well have been his own starfighter from Episode III).

While Darth Vader's armor may be old, the Dark Lord proves in this issue that it's not the machinery that makes him so formidable. His prowess and abilities as a Sith Lord are what makes him powerful as the Emperor's greatest weapon and servant. So long as the armor and prosthetics keep him alive to continue existing as such, there's no need for any further advancement. As the saying goes "if it ain't broke, don't fix it." However, it does seem as though Darth Vader will eventually need to replace his improvised battle droid limbs with his usual standard arm and leg prosthetics in order to resume his intimidating style once more in the Star Wars galaxy.
