After crashing his mother's A-Wing and getting into an argument with his father, Poe meets Zorii Wynn in a local cantina. Believing she and her crew are simple smugglers, Poe takes a chance and agrees to pilot them off-world, only learning afterwards they're part of the Kijimi Spice Runners, one the galaxy's most dangerous criminal syndicates. Believing he has no other choice, Poe stays with them, and develops a relationship with Zorii.
Refusing to help Zorii and her mother massacre the syndicate's rivals, Poe begins a riot and is nearly killed by Zeva Bliss, until her daughter intervenes to save his life. Despite Zorii's offer to lead the gang together and do better, Poe declines and flees. It is implied Zorii kills her mother.

At some point during a skirmish with the First Order, one of the pilots under Poe's command, Muran, is killed.
[Not canon-compliant retelling of an existing story] The Resistance falls under threat of the First Order's new codebreaking tech. Poe Dameron is assigned to investigate on Nar Kaaga, on the edge of Hutt Space. There, he discovers it's actually child prodigy named Cheka. He rescues her, returns her to her mother, and fakes her death so no future parties will try to use her brains for decoding messages. When Poe goes MIA during the mission, Leia negotiates with the Hutts to send a squadron in to rescue him.
Aboard Home One, alongside fellow pilots Karé Kun and Iolo Arana, Poe Dameron is assigned to steal Centrist Senator Erudo Ro-Kiintor's luxury yacht, the Hevurion Grace, to collect its computer banks for any evidence that he's working with the First Order. The recovered intelligence reveals a hologram of Lor San Tekka, and Leia decides to begin a search for her brother, to get him to rejoin the fight, believing he's the key for getting the galaxy to come together against the First Order's mounting threat. She entrusts Poe with this mission.
Now a commander of the Resistance's flight wing and Red and Blue Squadrons, Poe is reassigned and stationed full-time on D'Qar. At some point, Admiral Ackbar is captured by the First Order. With help from Threepio, Poe rescues Ackbar from a First Order ship, preventing him from being interrogated by Kylo Ren. Poe is awarded Rieekan medal for this.
Growing restless with his life, Han enlists Chewie's help to find the Falcon, and they return to their smuggling business. While inspecting the Resistance's new cruiser, the Raddus, Poe Dameron is caught in an ambush by First Oder TIEs, and is unable to return to the home cruiser when the hangar doors malfunction. Rose Tico is able to solve the malfunction, and get reinforcements to Poe, saving his life. This is how they meet. Sometime after, Paige Tico becomes one of Poe's wingmen in the Resistance's Navy.
Now aware that the Resistance is searching for Luke Skywalker, Snoke redoubles their effort to find the last Jedi, but keeps Kylo Ren from the hunt, believing his apprentice is not ready to undergo such a task. Agent Terex, an intelligence operative that survived the Galactic Civil War, with ties to the criminal underworld, is instructed to find him (and Lor San Tekka) first. Leia instructs Poe to form Black Squadron, and they undergo the Ovanis mission.
Near the end of the year, Poe begins believe there may be a double agent within their ranks. On a vaction between missions, he reunites with his old friend, a journalist named Suralinda Javos, and end up briefly captured by a First Order squad. He brings Suralinda to D'Qar, where she admits she'd planned on getting the location of their base, and selling it to the news network she worked for, but instead asks for a second chance and joins the Resistance.
Following a confrontation with Terex, technician Oddy Muva is revealed to have been the (unwilling) double agent within the Resistance, and L'ulo L'ampar is killed in a battle. Poe hands Terex over to the First Order, where he will be killed for betraying them and disobeying orders. The search for Tekka - and Skywalker - continues.

While investigating rumors of disappearing families on Athulla, Del Meeko is captured by the First Order, and interrogated by Kylo Ren due to his connection to Lor San Tekka. Discovering that Tekka had taken the map to Ahch-To to Bayora, Ren leaves Meeko behind to be executed by Gideon Hask.
Leia sends Poe and BB-8 to Tuanul Village on Jakku, to meet with Lor San Tekka to collect the map to Ahch-To. Before they can leave, the First Oder raids the village. Poe gives the map to BB-8 for safe-keeping, and runs back to help the villagers. Kylo Ren kills Lor San Tekka, and in a rage, Poe attacks his enemy and is subsequently captured. Ren orders the village to be destroyed. This event breaks the Cold War between the Resistance and the First Order.
On Jakku, BB-8 is rescued by scavenger, Rey. Aboard the Finalizer, Poe is interrogated by Kylo Ren, and unwillingly gives away that he entrusted BB-8 with the map. The search for the astromech begins. FN-2187 breaks Poe out of confinement, and the pair escape the star-destroyer in a TIE Fighter, where Poe then dubs him "Finn". They crash on Jakku shortly after, and Poe is presumed dead by Finn, who meets Rey and BB-8 on Niima Outpost, beginning a life-changing journey that leads them right into Han Solo and Chewbacca.
With the map to Skywalker in the Resistance's hands, General Armitage Hux is given permission to use the First Order's superweapon, Starkiller Base, for its first and only lethal demonstration. In a single blow, the First Order destroys the Hosnian system, wiping out the New Republic Senate and fleet, and leaving the Resistance vulnerable and without any support.
The Resistance engages the First Order on Takodana for the first time, marking the beginning of the Resistance-First Order war. They land a decisive victory, although Maz's castle is destroyed before they arrive. Elsewhere, Kylo Ren discovers Rey for the first time, and captures her - intrigued by a connection he feels with her, and knowing she's seen the map to Skywalker.
The Resistance launches an attack on Starkiller, and Han, Chewbacca and Finn infiltrate the base to shut down its shields and find Rey, who has now come into her Force abilities. While there, Han confronts Kylo Ren, and tries to bring his son home. In a move to prove his loyalty to Snoke and cement his fall, Kylo Ren kills his father, but the deed only fractures his resolve and leaves him more conflicted. While trying to escape, Finn and Rey are ambushed by Ren, who knocks Rey out and duels with Finn. After incapacitating Finn, Ren is shocked when his grandfather's saber goes to Rey, and not him. They battle, and Rey emerges victorious, as the planet begins its implosion, following Poe's successful bombing run on the thermal oscillator.
Artoo comes back online, providing the rest of the map to Luke. Leia sends Rey to complete Poe's assignment to bring Luke back, hoping that her brother will help train Rey. She, Artoo, and Chewbacca leave the Resistance, and journey to Ahch-To. There, Rey finds a disillusioned Luke who believes the galaxy is better without both him, and the Jedi Order. She also discovers a connection with Kylo Ren, where they can communicate with each other from lightyears away, and the two develop feelings for each other. Upon learning the truth of what happened the night the Temple was destroyed, Rey confronts Luke, and then leaves with the original Jedi texts, to go to the Supremacy to see if she can turn Ben Solo back to the Light.
The Resistance begins a full evac from D'Qar, but their efforts are interrupted when a First Order fleet drops out of hyperspace. Poe Dameron offers himself as a distraction, attacking the First Order dreadnought, the Fulminatrix on his own, as Kaydel Ko Connix finishes evacuating the last of the officers and supplies to their fleet. Although General Organa orders a full retreat, Poe disobeys orders and pushes on with a squadron of starfighters, and their bombing squadrons, to destroy the dreadnought, recognizing it as a fleet killer. During the battle, the Resistance sustains heavy losses, including all their bombers. Paige Tico is killed, while releasing the killing blow on the Fulminatrix, unkowingly preventing the fleet from later being destroyed.
Following the Battle of D'Qar, Leia demotes Poe down to captain due to disobeying orders and their heavy losses. Finn wakes up in the medbay. Dropping out of hyperspace in the Oetchi System to search for a new base, the Resistance is surprised by another ambush, with the full might of the First Order, including Snoke's flagship, the Supremacy.. During the battle, Kylo Ren destroys one of the Raddus's hangars, killing dozens of technicians and pilots, and destroying Black One. Although he is unable to fire on the bridge, after sensing his mother on board, another TIE fires on the vulnerable side of the Raddus, and destroys the command bridge, killing all of Resistance's High Command. Leia Organa only survives thanks to pulling herself to safety by using the Force, but is left in a coma afterward. Command of the Resistance falls to Amilyn Holdo, and morale quickly dims as she refuses to offer any help or promise of survival to her crew members, and their fleet dwindles down to nothing.
After discovering Finn attempting to abandon ship to prevent Rey from rejoining the doomed Resistance fleet, Rose Tico discovers a way to prevent the First Order from tracking them through lightspeed again. The pair take the information to Poe and Threepio, both of whom agree that Admiral Holdo would never agree to the plan. Poe goes through with it, and seeks out Maz Kanata's advice on how best to proceed. Rose and Finn then leave for Canto Bight, to find the codebreaker she promised could help them, but they're captured by local law enforcement before they can make contact. In prison, they meet a local scoundrel named DJ, but decline his help. After breaking out, they rescue the Fathiers, and offer hope to the kids enslaved on the planet. With little options left, they enlist DJ for help - at a steep cost.
Finn, Rose, BB-8 and DJ board the Supremacy to turn off the tracker. In a last ditch effort to buy them time, Poe, Kaydel and a handful of other Resistance officers, assume command of the Raddus after negotations with Holdo fall through. Rose and Finn are captured, and Poe is incapacitated by a recently awakened General Organa, then taken aboard a transport. Admiral Holdo stays behind on the Raddus, as the rest of the Resistance journeys to Crait. Kylo Ren kills Supreme Leader Snoke, after he tortures Rey and tries to have Ren kill her. The two fight his guards, but Rey cannot convince Ben to join her, and he assumes control of the First Order. DJ betrays Finn and Rose, and gives away that the Resistance is currently escaping to the planet below, and the First Order begins firing on the transports, destroying them. Eventually, with few shuttles left, Holdo repositions the Raddus to face the First Order fleet, and launches the cruiser into hyperspace, destroying most of the First Order's ships present.
The Resistance fights for its own survival, and try to buy time against the First Order's latest attack, to send out a distress signal. However, despite being received at multiple points, no one answers it. Finn attempts to sacrifice himself, but Rose prevents him from doing so, and is severely injured in the process. Inspired by Rey, and a conversation with Master Yoda, Luke projects an image of himself on Crait, to distract Kylo Ren and his forces, so that the Resistance can escape through the mines, where Rey is then able to free them from where the cavern has collapsed. She reunites with Finn, and Leia, and is introduced to Poe.
Following a duel with his former master, Ren realizes that Luke is not really there. Luke bids his nephew a farewell, and disappears. On Ahch-To, he passes away from the exertion of projecting himself through the Force, with a renewed sense of purpose, that is felt by both Rey and Leia.
