Ok so im writing a story inwhich takes place in 2095 and theres this race of alien, All other them are owned from birth by a Special human *Same as us, but have a special connection with there Light treader* but the creature kinda looks like Ravage from Transformers two *The big robot cat* But has a more cat like head and each has a different color of eyes. They are seven feet to shoulder and can speak through your mind or outloud. They are all either a black shiny metal or a silver shiny metal. Some are evil and some are good and basically ten special humans and there light treaders have to fight in a large dome arena. But anyways can you give me some ideas on how to describe them in a book and a better name for them? That would be awesome thanks.
