I can do the time skip. Though he's literally rocking a single mon for a good chunk of his career. How would I handle the power growth on that one pokemon exactly?

Well, if you are planning on going 1 mon for quite a while, you would be focusing more on that one rather than what others are doing focusing on multiple. So your Treecko's level would be higher than some of the others but not drastically.

So should I write the battle myself? Or do we titanpad?

Your preference. For smaller Nexus battles like this I'm fine with you writing it yourself. Only for the bigger ones are you required to titanpad.
