Following his discovery of Luke Skywalker, Darth Vader’s entire world was flipped upside
down, including his loyalties to Palpatine and Galactic
Empire.
Realizing his entire devotion to his Sith Master was based on complete lies and manipulations,
Vader started viewing the future of the galaxy ruled by only him and his son Luke
by his side.
Due to this, Vader did everything in his power not only to capture Luke in order to convince
the forthcoming Jedi to join him, but also ensure
that the Empire he still reluctantly served did not
kill Luke in its war against the Rebel Alliance.
One of the most significant cases of this was when Vader found out about Imperial Commander
Kanchar’s near success in killing Luke Skywalker during a mission.
Kanchar was one of the Empire’s most brutal and effective commanders, being someone who
was known to take things into his own hands, with him showing the physical scars of his
devotion as a result.
During the final years of his Imperial career, Kanchar was made overseer of the wealthy and
resource rich world of Shu-Torun, securing its safety from Rebel Alliance attacks.
He was one who expected the most out of his subordinates, following Vader’s playbook
of personally killing those who failed him too
many times.
Actually, Kanchar straight up looked up to the Sith Lord, being beyond impressed with
Vader’s accomplishments.
It’s also possible he felt some sort of bond with the Sith Lord,
seeing how he too had cybernetics.
Regardless of this, Kanchar made the mistake of doing his duty too well when he came close
to nearly killing Luke during one of his battles.
And an even larger mistake, of unknowingly proclaiming to not rest until he saw Vader’s
son killed.
This happened when an off the books Rebel Alliance strike team led by Leia and Luke
infiltrated Sho-Torun in hopes of destabilizing the entire
planet by taking out its main gravity infrastructure.
Doing so would have made the entire planet uninhabitable, but would have given enough
time to allow its citizens to escape.
When Kanchar became aware of this rebel attack, he quickly moved to defensive position with
his Star Destroyer.
After learning that Leia and her team were within the Sho-Torun royal castle,
and knowing that they needed to take it over in order to obtain codes for their mission,
Kanchar decided to initiate orbital bombardment towards
the entire castle in hopes of stopping them no
matter the cost.
Despite the fact that the loyal royal family was within the castle, Kanchar saw
their safety as irrelevant compared to stopping the rebels, as in his mind another royal family
would simply take their place to rule on his behalf.
Despite this overkill tactic of his, Kanchar was unable to successfully defend against
the Rebels, who were barely able to escape from his bombings
and succeed in their main mission of destabilizing Sho-Torun.
Following this failure of his, Kanchar was notified that Lord Vader had arrived to his
Star Destroyer.
Initially the Commander assumed it was over his failure in defending the planet,
beginning to take responsibility for his shortcomings.
But to his surprise, that was not why the Sith Lord had called for his attention.
In reality, Vader wanted to know why Kanchar had gone out of his way to destroy an entire
castle just to kill a small group of rebels.
Kanchar explained how Leia and her friends had been
recurring nuisances in the past, and that he would do anything in his power to destroy
them.
Then Kanchar perhaps made a lethal mistake, by stating that he would not rest until he
saw Leia and her friends killed.
Knowing full well at how efficient and dangerous of a Commander Kanchar was, and that Luke
was known to usually be with Leia during her missions, Vader Force Choked the man mid-
sentence, simply stating “No” while he strangled the man with the Force.
Completely taken aback as to why he was being killed, Kanchar tried to make sense of it,
but it was too late and he simply became another
corpse on the ground, with Vader stating how the
Commander shouldn’t understand as to why he did what he did.
As to Vader, keeping Luke alive and safe from death was all that mattered
to him, and he wasn’t going to risk some ambitious, cruel Imperial commander taking
his son away from him.
