Planet X wanted revenge. He wanted it badly. He wanted Jupiter and Saturn to suffer for ejecting him out of the Solar System. But how? Planet X thought and thought. Their moons? No, the two didn't really care for them. Neptune? Uranus? No, X couldn't hurt his own brothers. They seemed to dislike the two, but neither of them truly remembered anything of what happened those millions of years ago. Mars? Jupiter and Saturn cared for the rocky planets, but that wouldn't work. Earth? That was it. It had been Earth's fault he had even been ejected. Had Earth not been there when X threw Theia by accident, he'd still be in the Solar System. Added to the fact Earth was Jupiter and Saturn's favorite. It was perfect.
