I did it to illustrate my specie Niyassur (ニヤスル - Niyasuru).

Sorry the errors, I used the translator to write it. :[

In their feral form the males grow from 4x to 5x their original size. Their coat remains the same and one does not see many changes physically. Their strength, speed and defense increase loudly, they are true killing and eating machines.
Its speed ranges from 40 to 80 km / h in the form Anthro, in the feral the males can reach up to 120 km / h in a race.
