Chewbacca (or "Chewie", as he was known by his friends) was a legendary Wookiee from Kashyyyk and co-pilot of Han Solo's ship, the Millennium Falcon. He was the son of Attichitcuk, the husband of Mallatobuck, and the father of Lumpawaroo. Chewbacca carried with him the name of an ancient Wookiee hero, the great Bacca, first of the great chieftains of Kashyyyk, and the creator of a sword that denoted leadership among the Wookiees. This name placed Chewbacca in a noble lineage, which was further supported by his role in the Battle of Kashyyyk during the Clone Wars and during the Galactic Civil War.

Chewbacca was a wise, sophisticated being of great strength and loyalty. He was also a skilled mechanic. Chewbacca, like many Wookiees, was able to understand Basic, but he could not speak it due to his species's vocal structure. He instead spoke Shyriiwook, the main Wookiee language, composed largely of growls and grunts, to his non-Wookiee companions who typically replied in Basic.

He later died heroically during the Yuuzhan Vong War.
