Then, he said to Mykael and Colin : "Axel is going to use his final wolf form so be ready, just in case he manages to break that shield again in his wolf form."
Axel the wolf once Kevin had dropped all the Werewolves in the arena and his father confirmed that he could fight without worry, shapeshifted into his final wolf form, and he could feel right away the commotion that his transformation had caused in all the Werewolves.
His final wolf form was the most gigantic they had ever seen, not even their Supreme Alpha was that huge, and Axel who had the bloodline of the Dark Blue pack running through his veins was completely black as were all the pure bloodline members of their pack.
The only difference was that on his black fur ran golden tattoos like on his skin when he was in his human form.
And unlike the Alpha's and even the Supreme Alpha whose eyes were entirely silver when they used their power, Axel's were entirely golden.
