Super heroes are on my mind recently.
A villian has great powers and realizes that with every child he has his powers grow stronger. After fathering several children throughout the world he is an unstoppable force and gains complete control of the world.
Little does he know that each of his children share his power, and when his powers grow, so do theirs. When he realizes this he fights and kills the oldest, when he does his powers decrease slightly, but his children's do not.
The epic battle begins.
