So there is one question of Ninjago that I just don't get. Why is Zane the weird one, I know he's a robot and all, but why does he have to act so weird, and yet be one of the coolest ninja's in my opinion. WHY??

Well, it probably did have something to do with him being a robot. Not knowing much about his past or normal things. It was also probably put there for humor. If you have a problem with it, I'd take it up with the makers of LEGO, but you gotta admit, his weirdness did help a little to make him awesome.
