This picture was nuts when I drew it and it's still nuts. Benign and Tails get into a fight. Tails resorts to yanking on Ben's hair. Ben, being part lion, lets out a growling-scream similar to what leopards make, and scares the living daylights out of Tails.
Ben is a good guy now. He used to be a shadier character, but to this day, I can't figure out a reason that he and Tails would fight, especially physically.
