Fission Beings

, are smaller replicas of a Ten-Tails produced through its biological ability to perform fission.

Overview
Fission beings are extruded from the main body of a Ten-Tails, dividing pieces of itself into creatures of various shapes and sizes, broadly falling into a handful of distinct types. While most of these types are bipedal and humanoid, some take on a more bestial, quadrupedal form, and many have appendages that resemble weapons. Their sizes vary greatly, ranging from about the height of an adult human up to the that of a fully grown summoned creature. They physically resemble the parent Ten-Tails and have mouths and teeth, but lack eyes.

Among those produced by the Ten-Tails fought during the Fourth Shinobi World War, most were roughly the size and shape of an adult male human, with extremely long arms that had axe- or sickle-shaped blades protruding from their forearms. Others were about half that size and stocky, with spear-like appendages in place of forearms. Larger variants produced by this specimen ranged from about three times the height of an adult human up to the height of summoned creature, with a brutish physique with rotund stomachs. Many held yawara in each hand, while others carried spears or had sickles in place of forearms, and some even created spiked-shields. It also created a number of fission beings that superficially resembled wolves, being quadrupedal with tails, large angular heads, and mouths so wide that they extend nearly to the shoulder. In general these fission beings had two horns curving back from their foreheads, rictus mouths filled with sharp teeth, and spines covering their chest, shoulders, and backs.
