Tenuk holds an aggressive outlook towards his surroundings. He hasn't had the greatest beginnings when he was created, but as an adult he tries to move along from the past. It doesn't always work out when he is by himself and most of the time he is. He does travel with a close friend of his, but only when he travels.

He has a mix of browns and blacks in his fur patterns. His main color is black over a chocolate brown under belly.He has a brown mane running down his back, ending at a green scorpion tail, just as sharp as Ross's but even deadlier. The venom does not kill, but boils it's victim's blood from the inside out slowly and painfully.

His right hand is mechanical, due to a brutal accident while training with his brother. He was also injected with a R.A.G.E. serum , giving him the nickname of Rage.
