- Ristar originally only had angry eyebrows for boss fights; in the American version, they're present all the time.
- Narcis Prince of Punch Out will not let you touch his "beautiful, beautiful" face, so doing so is obviously his weakness, right? Yeah, except you just turned him into a British brawler, his "beautiful" face now has a growling sneer, and you better be quick on your feet if you want to beat him. That, or wait until he calms down ("Stay calm, matey!"). Luckily, his anger leaves his face exposed, allowing you to sock him in the face even more until he's knocked down.
