Zekk

Zekk (born 7 ABY) was a street-smart orphan from Ennth who befriended the Solo twins. After a fall to the Dark Side, he trained to be a Jedi Knight.

Early life
Zekk spent the first 9 years of his life on the planet Ennth, where his parents were colonists. When Ennth self-destructed, Zekk lost his parents. The other colonists wanted to send him to an orphanage, but Zekk sneaked aboard the freighter of a man named Peckhum, who took him in after they arrived at Coruscant.

While out and about one day, he met Jacen and Jaina Solo, and became fast friends with them.

Shadow Academy
Zekk's talent at finding hidden things were the glimmerings of untrained Force talent. This ability caught the attention of Tamith Kai, a Nightsister who was second-in-command at the Shadow Academy. Zekk was kidnapped, and twisted to the Dark Side by Brakiss, the leader of the Shadow Academy. After killing Vilas, Tamith Kai's apprentice, Zekk earned the title "Darkest Knight".

Zekk then lead the assault on the Jedi Academy on Yavin 4. Most of his Dark Jedi were killed, and in a last ditch effort, walked to the Temple, where he had a confrontation with former friend Jaina Solo, with her trying to turn him back to the light. After warning everyone stay away from the Temple, an explosive inside the Temple went off. Zekk had saved everyone.

Diversity Alliance
Zekk was asked to stay at the Academy and train as a Jedi, but he refused, fearing he'd fall to the Dark Side again. He then decided to go out and learn to be a bounty hunter.

Maybe it was the will of the Force, but Zekk's bounties always seemed to be connected with Bornan Thul, who had disappeared. He shared this info with Jacen, Jaina, Tenel Ka, Raynar Thul, and Lowbacca, and together they stopped the threat that was the Diversity Alliance.

Zekk then realized that he had too much of a conscience to be a bounty hunter, and finally had enough faith in himself to be trained as a Jedi.

New Jedi Order
Zekk was one of the members of the Myrkr strike team, and was instantly wary of the two Dark Jedi that the team rescued. His fears were proven right when they stole the ship that was to be used to get off the worldship, with Raynar still aboard.

Zekk then had to watch as his best friend Jaina started to turn to the Dark Side. Knowing he would go down with her if he tried to help, he decided the best course of action was to do nothing.

He was later chosen by Sekot to pilot a Sekotian vessel at the conclusion of the Yuuzhan Vong war.

Post-NJO
It is speculated that he may be one of the Jedi involved in the Chiss border dispute.
