Lucas was feeling unsure of himself. He wasn't sure if he should throw the Master Ball or just tap Mewtwo with it. Since he'd gotten the gift from Red (AKA Pokémon Trainer), he hadn't used it on any Pokémon. Lucas kept thinking, 'What better Pokémon to use it on than Mewtwo?' But he still felt dizzy whenever he thought about it.
Finally, Lucas had had enough. He rushed up to where Mewtwo was currently standing, investigating an odd vortex in the sky, shaped like a cat's eye, and threw his Master Ball with all his might. Mewtwo barely had time to react and jump out of the way before Lucas' Master Ball was sucked into the vortex.
"What the heck?" Lucas asked uneasily, staring at the portal that had swallowed his white-and-purple sphere whole. Mewtwo was in shock that had happened, and was prepared for a monster to come flying out. Instead, to its surprise, what flew out was a sort of evil moth thing, which stared Lucas right in the eye.
Lucas took an uneasy step back, turning slightly pale. "L-look...thing, I-I don't wanna hurt you," he stammered weakly as the moth flapped its wings rapidly. "J-just leave us alone, a-and I p-promise I won't h-harm you. J-just go a-away!"
Then the moth hissed, snarled, and charged straight toward Lucas, who became so paralyzed with fear, he couldn't move. The moth stuck its stinger straight through Lucas' heart, ripping out a glowing yellow ball of light in the process. And all Mewtwo could do was watch in horror as Lucas, albeit slowly, turned to solid stone. The moth smirked, the best it could with no visible mouth, and then flew back into the vortex.
Mewtwo gasped and shouted out, "It's headed for that...vortex...thing!" Even Mewtwo didn't know where the vortex led. But Pit and Dark Pit did. Their wings glowed a faint color, blue for Pit and green for Dark Pit, and together they ascended into the Chaos Vortex, Mewtwo and Ness in tow, albeit riding Kaelynne's Flygon. But before they got too far in, the vortex closed behind them, and Ness instantly knew they were in for a tough ride.
