Nightsickle MR4
Night Sickle

A strange breed of Ripper with a glowing blue body and a ghost-like form that allows it to stay nearly invisible. This monster's design is what precipitated the creation of the Modoki Monsters (in the English versions of the games they all end with "-ish", i.e. Pixie-ish). Although Night Sickle does not have the Modoki name, its design is exactly the same.

Etymology Edit

Named for its dark-blue color, which makes it blend into the night. Also for the sharp sickles on its arms.
