So, this is an insectivoreshipping / amourshipping one shot. Disclaimer, not owning pokemon and everything else. You know the drill. Now let's get to it.

It was nighttime in Laverre City as our heroes are resting up after a busy day. What everyone doesn't know is that by morning, a swap was to be made. As the sun rose, Serena and Ash woke up like usual. Only, they weren't in their own bodies. When they saw themselves in the mirror, they both screamed in schock as they saw themselves in their strongest pokemons' bodies. In short term, Serena was Braixen and Ash was Frogadier. Now this alerted Clemont and Bonnie as they saw the problem. Soon, Braixen and Frogadier, in their trainers' bodies, see what happened as they experience their new, hopefully temporary, form. As the morning kept on going, the two couples learned and found different likings to their forms. Ash found to liking Frogadier's speed and agility. With it, he can move almost as fast as Pikachu. Frogadier was really enjoying being in Ash's perspective. Braixen was also enjoying being within the perspective of her trainer. Though there were some things she had to get used to. The 2 main ones were 1, being used to wearing clothes and 2, not being covered in fur. Serena, who was getting used to being like her starter, also had some things to get used to. The main one was being used to having fur instead of her honey blonde hair. But, there were some positives in the situation. Now the trainers can use the pokemon moves like in a battle. The pokemon on the other hand, could now see what it's like being a trainer. Then, Serena ( Braixen ) had the perfect idea of using the situation to finally admit her feelings. She then challenged Ash ( Frogadier ) to a pokemon battle while they waited for Clemont, who was looking for a solution. Their pokemon ( trainers ) watched as they battled. Ash found using the agility to his advantage, making dodging attacks earlier. Serena was able to quickly learn how to use the branch in her tail. It went back and forth until they both accidentally tripped into a mud puddle. That was the moment that she pulled her crush into a kiss. Ash was a little schocked before he kissed back. Soon, the moment ended as they saw their muddy reflections. They both laughed a little as their pokemon ( trainers ) looked on with a little confusion. Once they both got cleaned up, Braixen ( Serena ) had a great idea. She then signaled Serena ( Braixen ) to come to her as Braixen ( Serena ) fished out the brush from Serena's bag. She then ran it through Braixen ( Serena )'s fur. Serena found it quite enjoyable as she understood how much her starter pokemon enjpyed it when she did it. Soon, she finished as Serena ( Braixen ) thanked her starter for the kind act. Meanwhile, with Frogadier ( Ash ), he trained a little with Ash ( Frogadier ). They both moved and jumped in sync as if they were one. Soon, Clemont came out with the potion to reverse the swap. As the four drank it, a flash overcomes them as they soon return to their bodies. Ash and Serena smiled as they hugged each other as Frogadier and Braixen did the same thing as they kissed while Ash and Serena did as well.

Well, that was adorable. I got the swap idea from the Freaky Friday movie. That plus two adorable xyz couples equals nice one shot.
