A clone of Jango Fett, Boba was created on the planet Kamino and raised as Jango's natural son, not undergoing the growth acceleration process applied to the Clone Army. Trained in the ways of the Mandalorians, he grew up to be a bounty hunter feared and dreaded throughout the galaxy, known for his subtle and cunning moves tracking down his prey. Fett commonly worked for the crime lord Jabba the Hutt, and held associations with Darth Vader and other political figures.
In books written before the release of the Star Wars prequel trilogy, he is not a clone, but a former Journeyman Protector named Jaster Mereel.
