Omega male
Omega is a scared wolf, just scared for everything around him, but especially for other wolves. He never dares to speak up or to come close, scared he'd be attacked again. He's always last, and gets only little food. He tries to help, but only gets bullied and attacked, so mostly stays a bit away from the pack.
It's a wolf...
Omega was born without a name, his parents never named him. All the pups always bullied and picked on him, making him scared. He became an omega wolf and ever since has been named Omega.
