As many of you know, the books and comics have filled in a little bit of history about Boba Fett. Or have they? The following summary comes from Bob Vitas' Completely Unofficial Star Wars Encyclopedia:

Boba Fett was known at one time as the Journeyman Protector Jaster Mereel. There are also rumors that Fett was an extremely dedicated Imperial stormtrooper who, for reasons known only to him, attacked and killed his superior officer. These rumors have never been substantiated. What is known is that Jaster Mereel killed a corrupt Protector but was imprisoned for the murder anyway. He was exiled from the planet Concord Down, and found employment as a bounty hunter, learning the skills that would make him a formidable adversary in the future. In his travels, Boba Fett acquired a full suit of Mandalorian Shock Trooper armor. The unique weapons systems of the armor suited a number of purposes, including enhancement of his arsenal as well as increasing the mystique behind his reputation. He also acquired an old Kuat Systems Engineering Firespray-class ship, which he named Slave I and had heavily modified at Kuat Drive Yards. Many of the modifications to Slave I were developed by Kuat of Kuat himself, and helped further the design of other starships. Fett employed the best microsurgeons in the galaxy to remove as many of the pain-sensing nerves from his body. He also had many of his body?s pleasure sensors eliminated as well. As his proficiency as a bounty hunter grew, so did his reputation.

Well, as you can guess from the Episode II rumors coming out about this character, you can forget all of this. George Lucas is wiping the slate clean on Fett and giving the character a whole new history. It's now up to the authors to make this history fit in with what's going to be revealed in the films. Based on recent discussions about this on StarWars.Com, Jaster Mereel will probably be written off as a Boba Fett impersonator - not the real deal. This has happened before in the comics where Fett battled a young bounty hunter trying to take over the Boba Fett persona. But all of this remains to be seen. And if this is the case with Boba Fett, you can bet money that other things will have to be rethought, too.
