The usual, two powerful Pokémon show up, and start to fight because of some kind of prophecy that the main characters undoubtedly figure out or already know, then you get a glimpse of the title Pokémon once or twice. and of course, there's the scene where everything falls apart, and Ash is always there to save the day, then the big "shocker" one of the main Pokémon dies, and the battle continues, somehow peace is made, and the more powerful Pokémon disappears, leaving the other one to put up with Ash's blubbering about how everything was destroyed. so, the damage is reversed, and everything is back to normal, then comes the mourning for the Pokémon that was killed in battle, as they walk away, pikachu sees a shadow, behold, the Pokémon is alive, then the credits start, the end. A closing statement: When Ash started to yell, I wanted Palkia to vaporize him and leave the rest of the people in space! I mean come on, logically, you can't just tell a super powered monster what to do and have the monster obey, see what I mean? it's so predictable!
