Vicious and difficult to train, the wild Nexu is not an uncommon sight on worlds with gladiatorial arenas or a desiring a big draw for big game hunters. The Nexu made their predatory living in the chilly forests on the Idona continent of Cholganna, world primarily made of rainforests and tree-based cephalopoids which the Nexu effortlessly hunted whenever they hungered.

Naturally agile, the Nexu had an odd feature which set them apart from most felines: a forked tail. Making up almost half their natural length, their forked tail acted as both a device to swing from trees as well as graspers when their paws or mouth weren't enough to get the job done. The majority of Nexu used their tails to wind up prey upon killing a particularly meaty kill, often bringing the carcass back to their nest.

Standing at one meter tall and four to five meters long, the Nexu have four sets of eyes: two to see as most sentient races do, including humans, and one to see on the infrared wavelength, leaving them to be hunters who cannot be fooled by conventional camouflage or simple hiding. Having superior reflexes to most animals they fight, the Nexu are flexible warriors. At one moment they can be swinging from a tree with their forked tail, or body slamming a fleshy combatant with the sharp quills which trail down their back. Their claws, as well, are extremely sharp. They can cut most humanoid species in half, several Mandalorian gladiators finding themselves slack jawed when the Nexu's talons cut directly through their beskar armor, leaving their entrails to pour out for a slow kill.
