Building upon basic designs of the Dantalion, this ship incorporates Bydo plant matter for armor and energy transmission. It's fitted with the barest of mechanical chassis, used only to provide systems that the Bydo bio-organism cannot possess, such as missile bays and Bit Conductors. One of the many branches of the Bydo Tissue program, this series explored the introduction of Bydo plant matter within the framework provided by a fusion of the Dantalion and R-9 technology, much like the B-1A Digitalius. Where the Digitalius was more about basic plant design, the Mad Forest series involved more tree-like growths.


Pilots must log 30 minutes of flight time with the B-1A Digitalius to unlock this ship.

One type of plant-like Bydo has a quality – named the BI Factor – much like Earth’s ivy. The B-1B was developed to exploit that quality. The result is the B-1B Mad Forest, featuring a special attack and regenerative ability.

Though the regenerative property of this ship was mentioned in R-Type Final, it actually has a game mechanic in this mission. Also, the ship's name has been slightly modified and is now a Bydo unit.
