Boltbeard was the captain of one of the various crews of pirates that plagued the Sol Zone, and maintained an island hideout. His leadership was eventually challenged by a partially rebuilt Metal Sonic v3.3, who soundly defeated Boltbeard. Disassembled, Boltbeard lived on in small measure as his opponent used his components to improve himself, taking the name Captain Metal in the process and claiming Boltbeard's crew for himself.
