Billy's third adversary was another well-built barbarian, but he could tell just by looking at the eyes of the guy that he wasn't an ordinary fighter. He had the brawn, the experience, and the brains to cause trouble for Billy. So, he raised his guard against that guy. Unfortunately, he couldn't be that cautious since the fights still could only last for thirty seconds.
The third opponent was a man in his twenties, but he had one hell of a black bear, to the point that he looked like a bear. Still, unlike his other opponents, the third barbarian assumed a defensive stance and waited for Billy to make the first move. That was quite the dangerous thing to do, but it means that he had some confidence in his defensive skills.
