- "Before the war, I was always told Jedi were good."
"I don't know anymore. There are a lot of terrible things happening… a lot of killing. And now my friends are saying the Jedi are to blame."
- ―Lux Bonteri and Ahsoka Tano
Lux Bonteri was the son of Separatist Senator, Mina Bonteri. Having been told once that Jedi were good, during the Clone Wars, Lux no longer knew what to believe after the Republic killed his father in a surprise attack. After his mother became a prominent senator in the Separatist Congress, Bonteri moved with his parents to the Separatist capital of Raxus. Reaching adolescence in a time of war, Bonteri took on many idealistic views and hoped, like his mother, for a peaceful resolution to the devastating conflict. A year into the war, Bonteri's views on the Republic and the Jedi were significantly tested after he personally met Ahsoka Tano for the first time.
Heroes on Both Sides
While conferring with Tano, Bonteri played a significant part in helping her see that the war was not as black and white as she presumed. He caused her to think twice about the Separatists and enabled her to see that they were not inherently evil, as she had at first contended. Tano and Bonteri grew in understanding of each other as time went on, each revisiting ideas of what had been a faceless enemy. However, these views were tested even further when he also lost his mother shortly thereafter in, what Dooku announced as, a "Republic attack". In truth, Mina Bonteri had been terminated by the Count's then Dark Acolyte assassin, Asajj Ventress.
A Friend in Need
Later in the War, Lux barged into a Republic-Separatist peace conference on Mandalore, and accused Dooku of killing his mother. After being seized by Separatist commando droids, Dooku confronted him via hologram and ordered two commando droids to kill him, but Ahsoka saved Lux. Ahsoka commandeered the Republic Diplomats' ship with the intent of taking Lux to Coruscant to grant him amnesty, but Lux stunned Ahsoka and took the ship to the new Death Watch base on Carlac.
Before the padawan awoke, Bonteri made sure to hide Ahsoka's lightsabers because he didn't want his new Mandalorian allies to know she was as a Jedi. After meeting with Bo-Katan and the other Death Watch members, he attempted to convince them that the Togruta was his future wife and thus was not a threat. The Mandalorians took Bonteri to meet with their leader, Pre Vizsla, and the two discussed killing Dooku after obtaining his location using Lux's holo-tracking device.
However, their plan quickly fell apart after Ahsoka revealed herself to be a Jedi in the course of saving a local village that had been enslaved by the Death Watch from total destruction. Realizing that Vizsla and his soldiers were nothing but murderers, Bonteri and Tano escaped with the help of R2-D2 back to their ship and quickly left Carlac. Although, before the ship reached the Republic, Lux jettisoned away in an escape pod after he said good bye to Ahsoka and promised that they'd meet again some day.
A War on Two Fronts
At some point later on in the war, Lux Bonteri allied himself with the rebellion of the Separatist planet, Onderon, to aid them in overthrowing their corrupt king. Lux fought alongside Saw Gerrera and Steela Gerrera attacking droid units.
Lux realized that the rebels could not free Onderon on their own. They needed proper training. Lux contacted the Jedi Council and Anakin Skywalker, Obi-Wan Kenobi, Ahsoka Tano, and Captain Rex were dispatched to Onderon to train the insurgents.
Once the Jedi arrived, they got straight to work. They showed the rebels how to take down an AAT tank and droidekas. Lux and Saw attempt to deactivate a tank but they both fail miserably. Next, they try to get a droid popper through the shield of a droideka. Saw fails and Lux succeeds. Lux tries to instruct Steela on the proper way to roll the grenade.
Eventually, Steela is practicing her sniper skills and is shooting the heads of Battle droids. She looks past the droid targets through her scope and sees real battle droids. They open fire and the rebels duck for cover. The rebels then return fire. Lux is behind cover with Saw and Ahsoka. Steela fires her sniper rifle and the blast opens the gates to the animal cages. The animals trample over the droids as they flee the battle. They destroy most of the droids.
The rebels then decided that it was necessary to take the fight to the Separatists. They disguised themselves and entered the city.
The rebels were inside the city of Iziz, carrying out attacks on small patrols of droids. While Lux and the rebels were destroying droids throughout the city, the civilian population began to fear the rebellion because they were unaware of their intentions. Lux suggested they hit something large, something that would show their strength and reveal their intentions.
The rebels went to a power generator station that provided power to the entire city, including the Separatists' droids. If the station is destroyed, the power grid will go out, bringing the droids to a stop. The only way to destroy it is to utilize a large piece of weaponry. They quickly formulated a plan to hijack an enemy tank to destroy the grid.
The rebels hid in an alleyway while Dono created a roadblock with a speeder. She hopped out and ran into an alley. A droid patrol approached the idle speeder, and it exploded when Saw gave Dono the signal. Some of the droids were destroyed, and the other rebels jumped out and fired on the rest of the droids. They left one alive long enough for it to call backup, hoping that they would send a tank.
Instead, they sent droidekas, spotted by Lux and Saw. Using their training by the Jedi, they destroyed the droidekas. Saw's droid popper worked, but Lux's bounced off, and alerted the droid to their presence. Firing on them, they took cover, and the droideka was destroyed by Steela.
The tank rolled onto the street. The rebels move in on it and Saw and Lux jump onto the tank. They both throw droid poppers in both hatches and the droids are deactivated. The tank is now under rebel control.
They drive the tank to the power generator station. Steela and Ahsoka provide cover for the tank to get in. Saw fires the tank's main cannon and blast through the door. Commando droids run out and attack Steela and Lux. They quickly defeat them and Saw fires the cannon again and the blast hits the generator. The station is engulfed in flames. The power grid is now offline.
Meanwhile at the rebel safehouse, Steela is elected the new leader of the rebellion. The Rebellion awaits their next target.
