Ben Skywalker, formerly designated as TN-4189 and nicknamed Ten, was a former TIE pilot who served the First Order. Having a strong connection to the Force, he would uncover the truth of his family's legacy and grew up to become a Jedi Knight of the New Jedi Order. A member of the Skywalker Family that lived on the desert world of Tatooine, Ben Skywalker was the long lost son of Mara Jade and Grand Master Luke Skywalker, making him the grandson of the famous Jedi Knight Anakin Skywalker and Senator Padmé Amidala of Naboo, and great-grandson of Shmi Skywalker. Born on Coruscant eleven years after the First Galactic Civil War ended, he was kidnapped by a group of mercenaries that worked for the First Order as an infant. Given the designation "TN-4189", he served in the naval forces of the First Order, serving as a pilot in the TIE Pilot Corps due to skills in piloting.
Before the Second Galactic Civil War erupted across the galaxy between the Resistance and the First Order, Ten experienced the same flashback of the time when he was kidnapped from Coruscant and barely saw the face of a red-haired woman wielding a lightsaber and trying to save him. When he began to learn that he was connected to the Force, Ten kept it secret for he didn't want to share it with anyone. When he witnessed the destruction of the entire Hosnian System and feeling the screams through the Force, he began to see that the First Order wasn't bent on bringing peace to the galaxy, only chaos and pain. Before the Resistance arrived to put a stop to the weapon that destroyed the Hosnian System, Ten didn't participate in the battle, for he chose to defect from his service and managed to flee the planet with a stolen TIE Fighter. Now that he was alone, his loyalty to the First Order came to an end, but feared that they would hunt him down.
During the conflict, Ten traveled across the galaxy to a find a world to hide on. Choosing the desert world of Tatooine as his place to hide, he would experience more visions that happened in the past during his exile. Seeing that these visions meant something, he began to uncover clues that would lead to who is family was. With the help and guidance from the spirits of Mara Jade and Obi-Wan Kenobi, Ten learned the truth of his heritage and that he was a "Skywalker". Changing his name to Ben and adding his surname, Ben Skywalker swore to carry on his family's name and began a new path: becoming a Jedi. He was among the allies that rallied together under the leadership of Lando Calrissian to reinforce the Resistance in defeating the Final Order and the Sith Eternal on Exegol, resulting the final demise of the Sith Lord Darth Sidious. After the war was over, Ben returned to Tatooine where he would meet Rey who carried the name Skywalker as well. With her help, Ben joined the New Jedi Order.
