Gen. I Pikachu and Hidden Power?

Question

So I'm gonna trade my pikachu over from my original yellow into either my silver or gold, but I was wondering, because the pikachu came from Gen. I would there be anything different about his hidden power? Or would it still be randomly based on his IV's from the first Gen?

Answer 1

If it is traded out of Pokemon Yellow, Pikachu becomes a normal Pikachu (except it will be holding the Light Ball). By this I mean it will be able to evolve, which it can't do in Yellow, and it won't be out of its pokeball, etc. Because of this I think that its Hidden Power will randomly depend on its IV's, and so could be anything.

Having said that, I couldn't find an actual source saying that, so I am happy to be proven wrong if someone else did find a source.

Hope I helped.
