Here are 5 cannon facts about Darth Vader. Number 1. Darth Vader's helmet contained neural needles that painfully connected with the top of Vader's skull and spine to form one interconnected unit. Without these, Vader could not use his four artificial limbs. Number 2. Due to the Sith Lord's inability to eat normally, Vader's helmet needed to be removed whenever he needed to eat, so that he could use a feeding tube in his private chamber. Number 3. In the event of damage to one set of his armor, Vader had a backup set which he kept in his quarters on board whatever vessel he happened to be traveling in at that time. This proved useful when he was attacked by swarms of bioengineered insects on by 2 and 0 BBY, which encased much of his armor in a sticky gray paste. Number 4. After Darth Sidious gifted Darth Vader the planet Moustaphar in the mask of the long dead Sith Lord Darth Momen. Momen's mask possessed several beings and designed Vader's castle which could channel the force energies from the dark side locus underneath the castle, allowing it to open a door to the dark side. And number 5. Around 14 BBY, Vader and several inquisitors were able to track down his cost, resulting in the Sith Lord killing the former Jedi Master.
