Theory: This theory, confirmed in the "Star Wars" universe with the release of "The Mandalorian" and "The Book of Boba Fett," posits that Boba Fett survived being digested by the Sarlacc in "Return of the Jedi." Fans initially speculated that his advanced armor and survival skills enabled him to escape.

Supporting Evidence: Boba Fett's survival was later depicted in canon, showing his escape from the Sarlacc and subsequent journey. His return in "The Mandalorian" and "The Book of Boba Fett" confirmed the fan theory.

Counterpoints: Before this confirmation, the theory was speculative and contradicted by previous canonical material suggesting Boba Fett's death.
