15. Mocking each other (May and Max)

if the siblings were permanently swapped as each other, they would get use to their new roles like:

Max as the big sister, would try Pokemon Training, battles and travels, thus put female version of his own clothes to fit his new body.

May as the little brother, would Unfortunately have to go back home and wait until growing up again. She would try also to put male version of her own clothes.

Even if they would try to work together, they would mocking at each other even more than before, no matter their new bodies types.
