Maybe he'd begin to dial back the battling, and continue on his original path of a professor, where Haxorus is a great example of how even threatening pokemon can become your friend and partner, or maybe after they've gone through the fire of battle together they find that's the only thing they want to pursue anymore.
This prompt would've been way different if I had rolled Barbaroach or something, but a strong dragon that needs to fight would likely lead to a pretty conventional trainer story.
