Lowbacca was different from the other trainees. For one thing, he wore no clothing except for a glossy syren fiber belt that held a small translator droid known as Em Teedee that interpreted his growls and grunts into Basic. Lowbacca also quickly became friends with a humorless Dathomirian girl named Tenel Ka.

Together, the Jedi initiates explored the jungles of Yavin 4. Lowbacca discovered an old, crashed TIE fighter that the young Jedi students repaired, only to be confronted by the still-surviving pilot, who kidnapped the twins and held them hostage until they were rescued. Only weeks later, the twins -- this time along with Lowbacca -- were again kidnapped on a visit to Lando Carissian's GemDiver Station. The perpetrator was a Nightsister from Dathomir, who schemed to turn the three to the Dark Side by forcing them to train at the Shadow Academy. Lowbacca was seperated from the twins, taunted, and mistreated. Eventually they escaped and returned to their studies.

During the hunt for Bornan Thul, father of fellow Jedi student Raynar Thul, Lowbacca discovered that his friend Raabakysh, thought dead many years before, was in fact alive. Raaba convinced Lowie and his sister Sirrakuk to check out the Diversity Alliance, with hopes that they would join. The Diversity Alliance turned out to be an anti-human extremist group, and with the help of his friends and the Chironian girl Lusa, the Alliance was brought down. Later, while Han Solo and the twins were attending the Ord Mantell Blockade Runners Derby with the former as Grand Marshal, Lowie, Zekk, and Tenel Ka made a surprise entrance into the race aboard Tenel Ka's ship, the Rock Dragon, and won. There the group met Anja Gallandro, who manipulated her way into their company. Lowie went on to help end the civil war on Anobis, and stop the takeover of Kessel, thereby halting the plans of the rebuilt Black Sun crime syndicate. I gave Lowie, along with his freinds, the title of Jedi Knight for their bravery.

Several years later, after the death of his uncle Chewbacca, Lowie, along with his cousin Lumpawaroo, would offer to assume Chewbacca's life debt to Han Solo. Lowbacca served well as a Jedi, reconnoitering in Yuuzhan Vong space with Tinian I'att. He went with the strike team to Myrkr to destroy the voxyn queen. He was betrayed and attacked by a Nightsister and her male student, who had been captured and tortured by the Vong. Luckily though he lived through the assault.
