Werelion Gai

You see?? Werewolfes/lions don't mean to be bad. They're just so aggresive because they are tired like this one.

I haven't drawn Gai as Werelion for some time and now I started practicing.

If you don't know, I interpret the reason why Gai is called "Beast" is, that he is something like a werewolf.
The whole thing is called "Beast-syndrome" and is a sickness that appears from puberty up to andropause. The animal you transform into depends on the blood/chacra-type of the person. The intensity depends on the mood and the way you can restrain it.
Instead of full moon the person transforms one night after the menstruation. (or when he would have it if he was a girl)
