Sol Rivas was a human male who served as a Lieutenant in the First Order. During the Battle of Starkiller Base, he accessed computer records which implicated Captain Phasma in the lowering of the superweapon's deflector shields. In an attempt to cover up her malfeasance, Phasma tried to kill Rivas. However, Rivas escaped in a TIE/fo space superiority fighter to the rocky, ocean world of Luprora. There, he was captured by the semi-sentient R'ora natives, who imprisoned him in their stronghold. Phasma tracked him down and killed him in order to hide her secret.
Sol Rivas trained as a pilot before becoming a Lieutenant in the First Order military. He was stationed at Starkiller Base during the outbreak of the First Order-Resistance War in 34 ABY. During the Battle of Starkiller Base, he accessed defense shield files which implicated Captain Phasma for her role in lowering the superweapon's shield. Phasma had done so under duress from Finn, Han Solo, and Chewbacca in an attempt to save her own life. The Resistance operatives had then thrown her into a garbage compactor.
After escaping the garbage chute, Phasma returned to the computer she used to lower Starkiller Base's shields and wiped the records clean of her actions. Realizing that Rivas had also accessed the computer and had proof of her betrayal, she attempted to detain Rivas and frame him for lowering the superweapon's shields and compromising its security. Spotting Rivas on Level Two, Phasma attempted to shoot Rivas, but ultimately failed due to the bombing runs of Resistance Forces. Rivas was able to escape to the surface with Phasma in hot pursuit. As the planet disintegrated around him, Rivas managed to reach an auxiliary hangar where he escaped aboard a TIE/fo space superiority fighter.
Rivas escapes aboard a TIE/fo fighter
Seeking to hunt down and kill Rivas in order to cover up her own malfeasance, Captain Phasma, the TIE fighter pilot TN-3465, and the BB unit BB-K8 gave chase in a TIE/sf space superiority fighter but were unable to shoot him down since their fighter's laser cannons were inoperable. Running shot on fuel, Rivas landed his fighter on the rocky, oceanic world of Luprora. Shortly after landing, he was captured by the native R'ora, a semi-sentient species of bipedal red skinned creatures with tentacles. Rivas was imprisoned at the R'ora stronghold, which the Lupr'or, a humanoid colonizing species, believed to be impregnable.
For four days, Rivas was a prisoner of the R'ora. He was bound by ropes inside the R'ora's tower and sustained a bruised right eye and several scratches from his captors. Intent on tracking down and killing Rivas, Captain Phasma led an assault by the Lupr'or on the R'ora stronghold. Phasma took advantage of the fighting to enter the tower where she found a bound Rivas. He was relieved to see Phasma at first. However, Phasma told him that she had come to execute him for his purported treason.
A defiant Rivas grinned back at Phasma and initially expressed ignorance. Phasma demanded that he confess to his alleged guilt and clear his conscience. Rivas countered that he had nothing to confess about and begged Phasma to spare his life in return for not telling anyone. When Phasma reiterated her demand, Rivas pointed out that she was the one who had lowered the shields and brought about Starkiller Base's destruction. Unwilling to take the fall for her actions, Rivas promised that he would not tell anyone. In response, Phasma shot him dead with her blaster rifle.
Unknown to Rivas, his execution was witnessed by TN-3465, who had disobeyed Phasma's orders to stay behind and guard the entrance. Before leaving Luprora, Phasma disintegrated BB-K8 and killed TN-3465 in an attempt to remove any remaining loose ends. Phasma then fabricated a report claiming that she had tracked down and executed Rivas for his alleged role in Starkiller Base's destruction.
Sol Rivas was human man with blond hair and blue eyes. He had a scar around his left eye and cheek. As a First Order officer, Rivas knew how to fly a TIE/fo fighter. Rivas regarded the R'ora of Luprora as savages for mistreating him during his captivity. As a result of his captivity, Rivas sustained a bruised right eye and several facial scratches. When Captain Phasma tried to coerce him into false confessing his role in Starkiller Base's destruction, Rivas remained defiant and tried to bargain for his life by offering not to tell anyone. Initially believing he'll be spared, he then realized that Phasma meant business, Rivas' defiance gave way to fear and desperation. To cover up her role in Starkiller Base's destruction, Phasma executed Rivas.
As a First Order lieutenant, Sol Rivas wore a dark tunic, belt, and trousers.
Lieutenant Sol Rivas first appeared in Star Wars: Captain Phasma, a 2017 four-issue comic published by Marvel Comics as part of the Journey to Star Wars: The Last Jedi promotional material. He was created by Kelly Thompson, illustrated by Marco Checchetto, and colored by Andres Mossa.
