In R-Type Final, an R-9A Arrowhead was infected by the Nomemayer, turning the ship into a Bydo ship. The ship was attacked by human ships and Bydo lifeforms and in response, the ship destroyed everyone in the crashed colony. The B-1D Bydo System Alpha later crashed and was salvaged by Humans who later used it for top-secret experiments.The B-1D Bydo System (α) Alpha is the first ship in the B-1D series.


This ship is unlocked by logging 30 minutes of general flight time with the B-1C Amphibian, but can also become the pilot's ship should they defeat the Nomemeyer.


[Bydo Mutant Sample]

Originally, this unit had no military code name. It is a salvaged wreck and was not developed by humans. At first it seemed to be a live Bydo life form, but analysis showed that an abnormal R-9A was inside, and the instruments have been attacked by the Bydo. The unit’s surface was marked with the label Bydo Mutant. It was appropriated for top secret research.
