As readers continue to show an interest I am blowing the dust off of my old notes for the Pokemon Trainer Class for Dungeons & Dragons 5e. So thanks for voicing your interest!
Keep two things in mind with leveling up Pokemon before you begin. First, all Pokemon have a starting level, so that Pidgeotto you caught is almost always going to be level 3 unless the GM did some tinkering to make it a bit tougher. Second, if a Pokemon’s level is higher than yours you have to make a Persuasion check to convince it to follow your orders.
Leveling up your Pokemon works in a manner very similar to leveling up a player character, but Pokemon don’t gain new powers until they evolve. This is mostly to avoid overloading players with too many options all at once.
In general Pokemon are really going to really only going to undergo large changes if or when they gain enough experience points to level up. That’s where you’ll see them gaining new features. Standard level ups usually just give them a slight increase in their health and a bump to their proficiency bonus.
You’ll notice that their proficiency bonuses are usually pretty low, there are two reasons for this. Wild Pokemon generally speaking, are believed to be weaker than Pokemon belonging to a Pokemon Trainer, which makes sense as they’re going to be in more battles. Mechanically speaking you’re also going to be pushing your Pokemons’ proficiency bonuses depending on your chooses as a trainer.
HP increase relies on the Pokemon’s type, and the chart below details how individual Pokemon’s HP will increase each level. This doesn’t take into account bonuses that can be gained such as the Breeder’s HP bonus. If a Pokemon is a dual-type you can choose any type for the HP gain.

If you’re looking at this and feel a bit disappointed don’t worry, the Evolution mechanic is much more exciting than the level up mechanic, and it is also where’ you’ll see exciting new options for your Pokemon begin to appear.
With that in mind keep checking for the Evolution update coming soon!
