Darth Caedus / Jacen Solo

Character from Star Wars Legends.
The son of Han and Leia Organa Solo, Jacen Solo was a leading Jedi Knight who proved crucial in defeating the Yuuzhan Vong and protecting the galaxy during the Yuuzhan Vong War. The grandson of Darth Vader, Darth Caedus was a Sith Lord who turned against his family and friends, betraying his former principles and leading the Galactic Alliance he once championed into a reign of terror as he attempted to bring order and stability to a fractured galaxy. It was Solo's desire to protect the galaxy and his increasing willingness to accept any cost in that cause that facilitated his fall to the Sith.

Born in 9 ABY, Jacen Solo spent most of his early years as the target of various kidnapping plots and schemes against his famous parents. When he was thirteen, he and his twin sister Jaina began attending the Jedi Praxeum on Yavin 4, where their uncle Luke Skywalker taught them the ways of the Force. There he made several friends, among them the Hapan princess Tenel Ka Djo, to whom he became strongly attracted. While training, he and his friends defeated numerous plots against the New Republic and, in 24 ABY, he and his younger brother Anakin were apprenticed to Skywalker. A philosopher who struggled with the idea of employing violence to fight violence, Solo entered a personal crisis with the outbreak of the Yuuzhan Vong War. He preferred to serve off the front lines, but felt obligated to volunteer for the strike team assembled to eliminate the voxyn queen at Myrkr. There, Anakin Solo was killed and Jacen Solo stepped up to lead the team, killing the queen and ending the voxyn threat before he was captured by the Yuuzhan Vong.
