King on Earth, by Aina Lozano
Once upon a time a villain came to Earth with evils intentions. The humans named it Corona because one of his primary intentions was crowning himself absolute king of the Earth. He began his mission and quickly managed to spread throughout the world, causing fear all around him. It seemed that he was going to get it, that he was going to take all the power. But suddenly, for the first time in history, citizens around the world agreed and with the collaboration of all managed to win Corona and throw him out to save the Earth from devastation.
