When the gods got bored, they created a game. the rules were simple: each god created one rider and gave the rider it's energy. the riders would fight over and over. each rider bore a gem of power: the gem resembling his god. for a rider to be destroyed, the gem must brake. once a rider is destroyed, the gem, as it brakes, will let out a ball of energy and if a rider catches it, it get's more energy as well as that riders element.
so, it's time for a new rider to rise, filled with awesome power- kamen rider... APPOLO!
