The Sea Creeper was an aquatic B.O.W. produced by the special mutation of a female human body infected by the variant t-Abyss virus. This special mutation tends to happen when a female body gets infected. The carapace looks like a woman's long hair which covers the entire body, reducing friction and allowing them to move freely underwater. It enables them to creep around the water silently. As soon as these monsters approach their targets, they spread their six human-like arms which they use to hold their prey while they eat them.
