Adderfang is a dark brown tabby tom with orange eyes and various scars across his pelt.
- He is a hostile, proud cat who barely has a soft side whatsoever. Getting to his kind side is near to impossible, though it can be done. Very few cats are able to gain his trust or friendship, and many cats are either disliked by him, or dislike him. Though, he is largely loyal to LunaClan, and will defend it with his life if he is opposed with such a threat.
- He is seen training for the fight against the Dark Forest. He is seen clawing a tree in several different ways and causing it to eventually fall down. He seems proud and walks back to camp.
- His ambition will get the better of him sooner or later.
