No, it wouldn't.If Arceus was destroyed, shouldn't Marcus have been destroyed also and indeed the entire pokemon world? How would killing Arceus made the world a better place, Marbi-Z? It would have destroyed it. Arceus is essentially God in the pokemon world and destroying it would basically destroy all matter in the pokemon universe.
Its joint Second for me, this and movie 13 are my Second Favourite movies of the series, followed by movie 12, then 10. First goes to the 1st movie though. But yeah, this movie was awesome, from the Ash and Dawn double battle, to the Credits! Twas great.This is my 2nd favourite movie for one reason: it had a great storyline
Although i found it really sad when pikachu died for a short moment
and piplup hugging dawn was adorable
I found it not to be that good actually, but its more a personal thing as I didn't really like the DP-Trilogy.This movie is tied for my #1 fav. movie. It was great having my favorite Pokemon Arceus featured in it. It was great to have Giratina, Palkia, and Dialga back in this movie. It was cool how they showed how the Plates work for Arceus to keep changing its type. It was cool that Giratina remembered Ash. It was cool to see a Heatran in this movie. It was cool how Ash and the gang went back in time to fix the problems and save Arceus from the surprising bad guy (not really surprising).
