In Real Life, the rhinoceros isn't anywhere near as aggressive or mindlessly violent as its been portrayed in the media. If the character is a bad guy, expect running. If the character is a good guy, expect a lot of trampled Mooks. When a character is based on a rhinoceros, expect a tough brute capable of a lot of violence. If it's a comedy, expect to see someone sent flying. If they're depicted in fiction, they're likely to be a dangerous obstacle. If they appear in a game, expect a Smash Mook or maybe a Bullfight Boss. They are one of the truly Badass species of animal in the world. They're not very smart, but they always use their heads. When portrayed in the media, rhinos are always hulkingly big, heavy, and intimidating animals that are known to have bad eyesight, short tempers, and a tendency to run down and trample (or gore to death) things that piss them off.
