Lloyd tried to attack with the Fangpyre Snakes well the two tribes, Fangpyre and Hypnobrai united and ranked Skales as they snake king. Lloyd then rescued all the other snake tribes well also they did not listen to his orders so Lloyd had no other choice just to turn into one of the ninja's. after a while, Pythor promised Skales that if Skales would help him to win in the Venom Pit fight Skales will control more tribes of the snake and be his main vise. Skales knew that Pythor's evil plan is to rescue the Great Devourer and that if Pythor would be swallowed by the Devourer, he would have a chance to be the snake king again.
