I have brought you here to curse you with the element of friction.
How are you doing that?
I'm slowing you down with friction.
Speed Demon's superpower is speed, so cursing Shiner with the element of friction will slow her down and make it possible for Speed Demon to rule the world.
Little did Speed Demon know, friction slows down objects moving at high accelerations. The friction he gave Shiner wasn't a curse, it was a blessing. As they ran at each other, their acceleration rate got faster and faster. but, Shiner slowed down Demon with fluid friction.
Speed Demon was slowed to a stop by Shiner and taken down for good.
