What If Serena appears in Pokemon the Movie: I Choose You! ?

Synopsis:

The story of Ash Ketchum and his bond with Pikachu started in Kanto through the Present. However, a different path shows Ash and Pikachu on the quest to find the legendary Ho-oh while facing new friends, rivals and Pokemon.

But what if he wasn't alone? What if his childhood friend Serena joins him on a journey instead?

This is my take of what it should look like if Serena stays in Kanto and start of her Pokemon journey on the same time Ash has his own with Pikachu.

My Thoughts:

Yes. This is my first Pokemon What if? Idea with Serena, one of the best companion and perhaps, the best Pokegirl to me.

I haven't watch the movie but since this was an alternate reimagined of Ash's journey instead of the original timeline, I imagine if Serena stays in Kanto rather than moving to Kalos and start her own journey on the same time with Ash. It was a great idea I got.
