Oooh, I got it. Make a specific quest line for each Pokemon. It can give them backstory, and what not. Eventually, you'll get to a quest that unlocks the evolution. This goes on until the final evolution is unlocked. Once that is unlocked, that final evo qualifies for certain "hardmode" quests that unlock even more Pokemon.

I know that making a quest line for every single Pokemon may seem repetitive, but if it does seem like that, you could instead make certain kinds of quests that fall into certain categories of Pokemon, just to make it easier.
