Beta Ray Bill is a fictional character that appears in comic books published by Marvel Comics. The character first appears in Thor #337 (Nov. 1983) and was created by writer-artist Walt Simonson. Debuting in the Bronze Age of Comic Books, the character was initially intended to be a surprise as an apparent monster who unexpectedly proves to be actually a great hero. As such, Bill becomes the first being outside of the Marvel Universe's Norse pantheon to be deemed worthy enough to wield Thor's hammer, Mjolnir. After an initial rivalry for possession of the weapon, both the Thunder God and the alien warrior, granted a war hammer of his own, reconciled as staunch allies.
