Why does Pikachu's pokeball change?

Question

Hi! I just watched an episode of X and Y where they show Pikachu's Pokeball.
Originally It had a lightning bolt above the button but the bolt has disappeared!
Why did it change?

Comments

nobody knows. it's likely a mistake that was never fixed.

I noticed this too. Don't bother too much about it, it won't change the story line at all.

Answer 1

It is just a minor detail error in the animation process. It will not affect the story or be a major issue to the series.
