Toreak was bred in a tame condition, and is comfortable around humanoids. It depends on humanoids for survival and looks to them for support. As creature handling goes up, a member can better understand and train and control this creature, but it will always look to Kojiro Keibatsu Sadow for guidance and support. When a character is proficient (+3) at handling creatures, they can do all they need with a domesticated creature.

Toreak is larger than the average Rancor in terms of size and body mass. Their bulkier build can offer better power but often at the expense of the mobility and agility commonly associated with other Rancor.

Toreak has a natural, instinctive drive to take the lead when around other creatures, especially when among fellow Rancor’s. They are usually the first to take point and will often look to assert their dominance by means of aggressive actions or by vocalizing with their respective method of communication (howling, hissing, roaring, etc.).

Kojiro's rancor has been altered by the alchemists of the Sadow. It's now bigger, brawnier and more horrific than the average bull rancor and standing at about 18 feet tall. The skin is now a mottled black, with patches of grey, greens and purples mixed in as if the body is constantly bruised and beaten. The tusks curl from the mouth, both ending in serrated points and above these, the creature's teeth are almost offensively yellowy green in colour as if they've been rotting non-stop. The eyes, once yellow, now gleam a deep red and carry a sense of wicked intelligence about them.
