Darth Vader was one of the most feared figures in the Empire. Imperial officers could lose their lives for failure, disrespect, or even saying the wrong thing at the wrong time. But one canon comic showed there was an Imperial officer Vader was not allowed to touch.
Not because Vader feared him. Because Palpatine still needed him.

Someone Inside The Empire Tried To Kill Vader
In Darth Vader #12, Vader is sent to Cabarria after the Empire receives a report about a possible Force-user.
But when Vader arrives, there is no Jedi waiting for him. Instead, he walks straight into a trap.
A group of mercenaries attacks him with weapons prepared specifically to kill him. Vader survives, of course, but the real danger is not the mercenaries themselves. It is who gave them the information.
After the attack, Vader has his droid trace the source of the mission. The signal leads back to Coruscant, and not just to some random Imperial officer. It points to the highest levels of the Imperial government.
That means someone inside the Empire had arranged for Vader to be killed.
The droid then gives Vader a list of people with the level of access needed to set up the trap. One of the names on that list is Wilhuff Tarkin.
Palpatine Let Vader Make An Example Of Them
After Vader discovers that the assassination attempt came from inside the Empire, he brings the information to Palpatine.
Palpatine makes it clear that he was not behind it. He tells Vader that men like them will always have enemies, even inside their own ranks. But Vader does not want to ignore what happened. If Imperial officers believed they could move against him and survive, then they needed to be taught exactly what he was.
So Palpatine allows him to respond.
He gathers the Imperial officers together and makes Vader’s position clear. Vader is not just another servant of the Empire, and he is not just a military enforcer. Palpatine tells them that Vader speaks with his voice, meaning that a command from Vader carries the same authority as a command from the Emperor himself.
Then Vader steps forward and punishes the officers who had moved against him.
It is not just revenge. It is a public lesson. The Empire needed to understand that Darth Vader was not someone they could plot around, challenge, or treat like a replaceable weapon.
Tarkin Was The One Officer Vader Had To Spare
Palpatine gives Vader permission to punish the people who tried to have him killed, but he makes one thing clear: Tarkin is not to be touched.
The reason is simple. Palpatine still needs him.
That detail says a lot about Tarkin’s place in the Empire. He was not protected because Vader feared him, and he was not above Vader in raw power. He was protected because he was too useful to lose.
Most Imperial officers were replaceable. Tarkin was not.
He had the Emperor’s trust, the mind of a strategist, and the authority to command some of the Empire’s most important military operations. Vader could terrify officers, choke them, or kill them when they failed, but Tarkin was one of the few people Palpatine would not let him remove.
