M'ss'y opened the mysterious letter adressed to her.

M'ss'y O'C'nn'r, alias Princess Unicorn,

You may know that every superhero in the world has been abducted by some unthinkable evil. I propose we, as competent heroes, stop this unthinkable evil. We each have our abilities. I cannot think of anyone more capable of freeing the world's favorite heroes than M'ss'y O'C'nn'r, Lucas Williams, Garfield Ross, and me, Joyce Johansson.

M'ss'y was surprised by this proposal, and excited. But, who were 'Garfield Ross' and 'Lucas Williams'?
Well, she wouldn't have to wonder for long.
Gar and Luke both got almost identical letters. They were to to save the world.
