Rocky and Robby Keene were the best of friends, even though Rocky was younger. Both brothers grew up with their mom, though she was almost as bad as their dad. Never being home, always running off with the guys she meets, leaves the brothers free to do whatever. Their lives are pretty shitty, until they meet Daniel LaRusso. He turns their life back on track. Well it was back on track, until new people show up, causing problems with the brothers. But things get particularly bad when Rocky stands up for Miguel, the brothers, or rather Robby's, enemy. That results in a fatal accident. After that day, the brothers were never the same. Fights, screaming matches, and insult battles are always breaking out when the two interact. But they have to get along again, right? They need each other, don't they?
