Why do all of the main protagonists in Yu-Gi-Oh! have crazy hair?

Because they're awesome that way! XD

i would say because thats the way the animators chose to draw them... but Jaden and Alexis dont have really freaky hair.. what do u think?

because crazy=SAVING THE WORLD
naruto
yugioh
yugioh 5Ds
yugioh GX

Im not sure, but i guess its just how the creators drew them.
