Corrupted Vor

Corrupted Captain Vor is the hidden boss in the Orokin Void as a small encounter chance in Tower IV missions. It is known that he was revived by his own Orokin Key during a normal assassination mission in Mercury.

Appearance
Corrupted Captain Vor still resembles an aged light Grineer in unique brown armor. With exception of his body being separated from his torso, linked by solely his Orokin Key.

Taunts
Corrupted Captain Vor's list of taunts are listed here:
 * "My brothers, did I not tell you of this day? Did I not prophesize this moment?"
 * "Now! Now, I will stop them. For I am changed, blessed by the energy of this Janus Key. Reborn and forever be bound with the void."

Upon Defeat

 * "This death is temporary. My existence is forever. I cannot be destroyed.

Lore
During The Call, Captain Vor is seen to be landing on an excavation site of an assumed planet, possibly due to the news of an Orokin portal being found, along with the fact that it can only be opened with a special device and an Orokin Key. As he unlocks the portal and approaches over the just-awakened Excalibur (in the void), other Tenno came into the rescue and exterminates his troops without ease, with Captain Vor ultimately being slashed into two by the awakened Excalibur. After an indeterminate amount of time, his Orokin Key is shown to be reviving him, ultimately linking his separated body together, and lives once more. It is unknown whether he has been convinced by his revival, or has been brainwashed by his own Key. Either way, it is known that from this point on, he considered the Orokin as a godly being, going so far to call his Orokin Key as a Janus.

As seen in The Rebirth, the newly-revived Captain Vor is seen to be marching his way through the Grineer troops as he uses his Orokin Key to show his "Godly" power to the troops, to their surprise, they slowly kneel down on Captain Vor in their worshipping, leading to possibility that he marches his Grineer follower into the Void, ultimately converting their faith into the Corrupted. And thus is why Captain Vor lives inside the Void.

Trivia

 * Much like Councilor Vay Hek, Captain Vor supposedly never truly dies, only to be revived once again by his Void key (In Hek's case, he flees from the players after his Terra frame is significantly damaged). This allows the fact that you can kill him multiple times to fit into the actual lore of the game, unlike other bosses.
