The Unnamed Trench Umbra is a mysterious and little-understood member of the aquatic Umbra family. Known for its blubbery body and distinctive physical features, this creature is adapted for life in the deep ocean trenches. It has a large set of tail fins and two pairs of small, pudgy legs. Its bulbous head is adorned with short forehead horns, and it sports external frilly gill structures on the sides of its face, along with a set of whiskers.

Currently, this young Umbra's blubbery body is more suited for floating along the water's surface, but it is believed that as it matures, it will become a swift and formidable swimmer. Despite its current docile and harmless appearance, Umbras are known for their fearsome nature, and this creature is expected to grow into a large and dangerous predator in the future. For now, however, much about this mysterious species remains shrouded in mystery.
