My friend DragonkeeperSherlily suggested to me to draw my characters angry. I decided to draw some differences between four of my characters.

Dang it I forgot his black ear cuff but oh well. Anyway, Rogue and ken yell a little when they're frustrated but when they get truly get angry.... Well

It doesn't end well for the person on the receiving end.
Nero and Starlaon the other hand get pretty quiet when frustrated. But when they really get mad, they explode.

I'm sure you can imagine their fury.
