The "Red" Skeleton is an enemy from Rosenkreuzstilette Freudenstachel.
The Skeleton cannot be permanently destroyed; when attacked, it will crumple, but it will get back up shortly after. They are based on the Blood Skeletons from the Castlevania series.
They are only found in the Phalanx Cathedral Ruins (Eifer's stage).
- Despite the Skeleton's blue colorization, the enemy is referred to as "redscull" in the games files in reference to the Blood Skeleton, giving it the misleading official name "Red Skeleton".
