I couldn't believe what Professor Oak was saying.
"Six legendary birds?! I thought there were only five! I mean, aren't Articuno, Zapdos, Moltres, Ho-oh, and Lugia enough?"
"Apparently not, this is a very special pokemon. It is Psychic/Flying and practically unbeatable EXCEPT BY ALL THE OTHER LEGENDARY BIRDS COMBINED. It is terrorizing Celadon City as we speak. YOU HAVE TO CATCH HIM BEFORE HE KILLS. You have 3 out of the five needed to capture him. Now I need you to catch Ho-oh and Lugia. They are unbelievably powerful, so you will have to fight to capture them, Mewtwo."
*I will do all I can to help.*
"Good. Here, take these. They are my latest inventions, called Master Balls. They will capture most pokemon without fail, but, just to be safe, weaken Ho-oh and Lugia some first. Now, go and release Articuno, Zapdos, and Moltres, get on their backs, and make them pretend to fight. Lugia will rise and fight. Zapdos and Articuno will have to attack together. Since Lugia is a Water/Flying type, you and Molter should stay away from him, Ash."
"Aww, c'mon Professor."
"No buts. Now get going. Come back when you have him and I will tell you what to do to capture Ho-oh."
"Ok, Professor."
We left the lab, flew over the ocean and began. Articuno Zapdos and Moltres began to playfight. They created a magnificent explosion that echoed like a gunshot. Then, a huge pillar of water arose from the sea and quenched the fire. Lugia burst from it and went on the attack. He shot a huge flood of water at Ash and Molter, but they escaped it when Mewtwo and Zapdos created a psychically controlled ball of electricity and fried him. He began to fall, but Mewtwo created a pillar of water and Artie froze him in it. He was trapped. I flung a Master Ball at him. He was sucked into it and it flew to my hand. We had 4 out of 5. Mewtwo teleported us back to the lab where he collapsed, exhausted. He somehow staggered upright and tottered into the lab where Professor Oak was waiting for us, and caught Mewtwo before he fell. Oak pulled a potion from his pocket and sprayed Mewtwo with it. Mewtwo stood up, rejuvenated. Oak asked if we had Lugia, to which I replied that we had just captured him. Oak, to my great surprise, leapt into the air and whooped! He calmed down and congratulated us, then told us to get a good night's sleep. We didn't know it, but we would need it.
