Hasbro codes, or simply just "Codes" as many people refer to them, are alphanumeric codes that are included with every Hasbro Beyblade toy purchase. To use these codes, you simply log on to www.beybladebattles.com, and then enter your code. This enables features such as: * Being able to create your own custom beyblade, IR Spin Beyblade, Tornado Battler or Electro Battler. * Being able to battle against other bladers online instead of a computer-controlled player.
