Manth is a Bydo enemy in stage 6 and stage 7 of R-Type II and Super R-Type, respectively. It quickly rushes out of the organic walls, dashing at invaders and attempting to destroy them with a quick ram attack. They frequently attack in hordes and only flawless piloting skills and/or a fully-outfitted R-craft have a chance of surviving the onslaught.
A creature on the Bydo emperor planet. Ironically its gene structure is very similar to that of a human being.
This space creature has the charm of an asteroid and defenses to match. Attack with caution.
It's called Mangler in Super R-Type.
