What I find interesting is that in the series itself they seem to be completely different people. However, we then get to the Victini movie and they're right back to how they were in basically most of the movies, if not all of them. This brought me to the conclusion that if they have a very specific goal in mind with specific steps thought up by someone else that they can actually amount to something. However, when they're just something on a whim or thinking of something completely on their own they don't think things completely. But I'm still fairly early in the unova series so I'm not sure if anything counters this logic or not.
