Short answers, pulled from the story.
Oscar Isaac portrays Poe Dameron, beginning with the 2015 film The Force Awakens. He reprised the role in The Last Jedi, The Rise of Skywalker, the animated series Star Wars Resistance, and several television specials.
Poe Dameron was introduced in The Force Awakens in 2015.
The script originally had Poe dying early in the story. Director J.J. Abrams rewrote it so the character survived through the entire film.
Poe's mother, Shara Bey, was an A-wing pilot who adventures alongside Leia Organa. His father, Kes Dameron, served with the Pathfinders, a Rebel Alliance ground force led by Han Solo.
The Rise of Skywalker reveals that Poe once worked as a spice smuggler before joining the Resistance, abandoning his crew and friends to do so. Some critics felt the reveal did not match the character's earlier portrayal.
Critics including Michael Phillips of the Chicago Tribune and Manohla Dargis of The New York Times described Poe as a next-generation version of Han Solo. Richard Roeper of the Chicago Sun-Times wrote that Isaac has more than a bit of Han Solo's swagger.
