You've probably been there. It’s late, you’re looking at your 5e Monster Manual, and you think, "Why can't I just throw a Pokeball at this Owlbear?" It sounds like a dream. Combining the tactical, high-stakes combat of Dungeons & Dragons with the "gotta catch 'em all" addiction of Nintendo’s flagship franchise is basically the holy grail for a specific subset of nerds. But here is the thing: Pokemon Dungeons & Dragons is notoriously hard to get right.
Most people just try to skin a lizard and call it a Charmander. That sucks. It fails because D&D is built on a "bounded accuracy" system where a single character gets stronger over time, while Pokemon is about managing a literal army of shifting stats and elemental rock-paper-scissors logic. If you just drop a Pikachu into a standard Waterdeep campaign, you’re going to have a bad time.
The Problem With "Official" Pokemon Dungeons & Dragons
There is no official book. Wizards of the Coast and Nintendo are like two massive celestial bodies that refuse to collide because the legal paperwork would create a black hole. Because of this, the community has had to build its own bridges.
You’ve likely heard of Pokemon 5e. It was the gold standard for a long time. It was a massive, sprawling fan project that converted every single monster, move, and mechanic into the fifth-edition framework. Then, the inevitable happened. Legal notices flew, and the primary PDFs were scrubbed from the main sites. You can still find them in the dusty corners of the internet—r/Pokemon5e is a ghost town of "does anyone have the link?" posts—but it highlighted a massive issue.
Relying on a direct 1:1 conversion of the video game into D&D is a recipe for a headache. The video games use a complex internal math system for Effort Values (EVs) and Individual Values (IVs). If you try to track those at a physical table with dice, your session will turn into a math homework group real fast.
Why Most Homebrews Fail
Balance is the killer. In D&D, the Action Economy is king. If you are a Trainer and you have six Pokemon, and you can call them out, do you get six turns? Does the Pokemon take your turn? If the Pokemon dies, is it "fainted" or is it dead dead?

Most homebrew systems stumble here because they try to make the Trainer a class. But a Trainer without a Pokemon is just a guy in shorts. If the Pokemon is the "class feature," then the player is essentially playing a glorified Beast Master Ranger, which—let’s be honest—has been the most complained-about subclass in D&D history for a reason.
Better Alternatives: Pokemon Tabletop United vs. Re-skinning
If you’re serious about a Pokemon Dungeons & Dragons crossover, you have to decide how much "D&D" you actually want in there.
Pokemon Tabletop United (PTU) is the heavy hitter. It’s not technically D&D; it’s its own d20-based system. It is crunchy. Like, "breaking a tooth on a jawbreaker" crunchy. It features hundreds of edges and capabilities. You can play as a psychic trainer who fights alongside their Mewtwo, or a martial artist who punches stuff while their Machamp watches.
But if you want to stick to the 5e we all know, you should look at Pokemon: Fifth Edition (P5e) or the newer Pokemon 5e: Gen 1-8 manual that still floats around Discord servers. The key difference is how they handle the "Action." In these systems, you generally use your "Bonus Action" to command the Pokemon and your "Action" to do Trainer things like throwing items or using medicine. It keeps the game moving.
The "Monster Tamer" Class Hack
Some DMs realize that they don't need a whole new system. They just need a better class.
- The Shepherd Druid: Honestly, this is halfway there already. You summon spirits, you talk to animals, and you buff your "summons."
- The Battle Smith Artificer: Swap the Steel Defender for a Porygon. Boom. Done.
- The Beast Master (Tasha’s Version): Use the "Primal Companion" stats but describe it as a Growlithe.
This is the "Path of Least Resistance." It doesn't break the game because the math is already vetted by the designers at Wizards of the Coast. You aren't reinventing the wheel; you're just painting it red and white.
Creating a Campaign That Doesn't Feel Like a Slog
The biggest mistake is starting with six Pokemon. Don't do it. Your players will spend forty minutes on a single turn deciding which move to use.
Start everyone with one. Just one. Make that Pokemon feel like a character. In a true Pokemon Dungeons & Dragons setting, the bond matters more than the Pokedex completion percentage. Give the Pokemon a "Personality Trait" and an "Ideal" from the Player's Handbook.
Maybe the Bulbasaur is "brave but stubborn" and refuses to retreat even when it’s at 2 HP. Now you have a roleplaying hook, not just a stat block.
Setting the Scene: Kanto vs. Faerûn
Do you set it in the Pokemon world or the D&D world?
If you put Pokemon in Faerûn, they are magical beasts. They are rare. A Pikachu is a lightning elemental that scholars are trying to study. This is "High Fantasy Pokemon." It’s cool because the stakes feel higher. If a Team Rocket equivalent (maybe a branch of the Zhentarim?) steals a Pokemon, they aren't just taking a pet; they are seizing a biological weapon.

If you go the other way—bringing D&D races to Kanto—you get a weird, corporate-fantasy vibe. Imagine an Orc trying to fit into a PokeCenter or an Elf who thinks PokeBalls are unethical soul-traps. That’s where the real comedy and drama live.
The Technical Stuff: Stats and Scaling
If you are homebrewing, use the "CR" (Challenge Rating) system carefully. A CR 1/4 creature is roughly equivalent to a Level 1 Pokemon.
But Pokemon grow fast. In D&D, you might level up after three or four sessions. In Pokemon, you expect growth every fight. To fix this in Pokemon Dungeons & Dragons, use a "Milestone Evolution" system. Don't track XP. It’s a nightmare. Tell your player, "After you defeat this Gym Leader (or Boss), your Charmander evolves."
It keeps the power spikes predictable. You don't want a Charizard in a party of level 3 players. It will melt every encounter you build, and the other players will just sit there feeling useless while the fire-breathing dragon does all the work.
Real Talk About Legendaries
Don't give them out. Period.

A Legendary Pokemon in a D&D setting is essentially a Lesser Deity. If a player catches Rayquaza, the campaign is over. You can't challenge them anymore. Treat Legendaries like the "MacGuffins" of the story. They are the things the players are trying to protect or prevent the villain from waking up. They are environmental hazards, not party members.
Actionable Steps for Your First Session
If you’re ready to start your own Pokemon Dungeons & Dragons journey this weekend, do this:
- Pick your System: Go with the "P5e" fan-made manuals if you want the full experience, or just use Tasha's Cauldron of Everything "Sidekick" rules for a simplified version.
- Limit the Roster: Tell your players they can carry three Pokemon maximum, and only one can be "active" in combat at a time. This saves the action economy from collapsing.
- Simplify Types: D&D doesn't have "Bug" or "Poison" as a core weakness/resistance system in the same way. Stick to D&D damage types. "Fire" is "Fire." "Electric" is "Lightning." "Grass" is "Poison" or "Necrotic." Don't try to port over the 18-type chart; it's too much to track.
- The "Trainer Move": Give the human players something to do. Let them use their Help action from a distance or use a "Reaction" to call out a command that gives the Pokemon Advantage on a saving throw.
- Ban Revivify on Pokemon: Make "Fainting" a real condition. If a Pokemon faints, it needs a Long Rest or a specific high-cost item (Revive). This keeps the tension high.
Honestly, the best games happen when you stop worrying about the "rules" of the video game and start focusing on the "feeling" of the journey. D&D is about the adventure between the towns, not just the fight at the end of the road. Let your players get lost in the tall grass. Let them fail a check and have a Spearow steal their rations. That's where the magic is.
Stop reading and go find those PDFs. Or better yet, grab a Monster Manual, find the "Wolf" stat block, call it a Poochyena, and start rolling dice. Your players won't care about the math if the story is good.
