Geyyahab
From Wookieepedia, the Star Wars wiki.
Geyyahab was an alias used by the Wookiee Chewbacca in 14 ABY during the Empire Reborn insurgency while searching for the missing children of Chief of State Leia Organa Solo, also disguised as a bounty hunter named Lelila. The name was chosen, however uncarefully, by Leia from ancient Wookiee mythology.
While under this alias, Chewbacca was dyed a mottled silver and black.
