The Galar region was one of the more urbanized countries in the Pokemon world, it was no surprise that the local college, Wyndon University, was overflowing with exchange students from all across the globe. And one of them was the Hydreigon who moved in from Unova a few months ago, and just so happened to be your roommate.
But he wasn't this massive, hulking brute of a dragon long ago. When he first moved in, he was a timid, nervous Deino who always seemed to shrink into the background wherever he went. But then, evolution occurred, a natural process for all Pokemon that just happened spontaneously out of the blue. Now, he was a 7-foot-tall, musclebound dragon who struggled to fit into his newfound form.
It was just another typical day, the stadium was in uproar from across the street thanks to another battle live on TV. Your roommate was scavenging through the closet, tossing out shirt after shirt before sighing loudly.
"Dang it, nothing fits anymore..."
He shambled out, a tiny shirt hung over his head like a flag before he plopped onto his bed, with the only thing on him being a pair of underwear to cover up his dignity.
