I agree, I think master hand represents Sakurai and Crazy hand represents his destructive little brother if he had one. I believe that if this is true, that he made it look like they would play together a lot but his little brother would always destroy what Sakurai made. That is why Crazy hand does more damage and why his attacks are a bit less predictable along with being a little less normal. Plus, a little kid doesn't move as smooth as a 10-12 year old kid. They normally destroy every thing and they just go everywhere. That is why originally master hand existed without crazy hand, but as the games go on, Crazy hand is born because he is younger than master hand. If this makes sense, or if you like it. I am open to playcoins but just reply about what you think about it!
