Oppaimon is a Pokémon based eroge game. It joins the list of Pokemon based erotic games like Pokemon Ecchi Version.


You just turned 18 and you have become a legal adult. Now, you are free to explore the lands of Fuckto where you can discover, seduce and have sex with Oppaimons. Can you capture them? Can you train them? Can you use them to fight other Oppaimons? Can you seduce them? How many sexual positions can you try when you have sex with them?


The major goal of the game is to capture all the Oppaimons and have sex with their trainers. You can beat trainers of each gym and collect money which can be used to purchase items like Oppaiballs and energy shots. After beating them, you can take part in sexual actions like cumplay, foreplay, squirting etc.

You get limited attack move points and health points. You can’t make attacks without the attack points. You have several types of attacks that are named for sexual innuendoes. You attempt to knock out other enemies with your Oppaimon. There are also some minigames that you can play. You can select Oppaimon characters of your own. Your Oppaimon gains XP and levels up after some time. You can use more than one Oppaimon for some battles. The game features various towns, areas, stores, hotels and gyms with varying enemies.
The game is glitchy and there are a lot of bugs. The game freezes numerous times. Sometimes, you’ll try to save and you’ll have problems saving the game. Also, you may get issues trying to run the game in some screen resolutions.

Character Customization

You can customize some things about your game character to fulfill your fantasies. You can customize the hair, ear, eyeball, skin color, and other features of your in-game character. The customization options are pretty limited for now, but the developers promise to add more development features. You can only play as a female but in future updates, you’ll be able to play as a male.

Pokémon Elements

Oppaimon borrows a lot of elements from Pokémon games but renaming them. For example, Pokeballs are called Oppaiballs in the game. Instead of unlocking and collecting Pokémons, you collect Oppaimons.

Game Updates

The game isn’t complete. The developers release monthly updates. Their plan to have a total of 181 Oppaimons in the game with more gyms, special sex scenes, and more regions. The game modes will be improved, the dialogue will be improved and the story will be expanded. The developers are also planning to make the game fully 3D.


Oppaimon is a good Pokémon based eroge game. But the game is plagued with several bugs. If you can, you should wait untill the bugs in the game are fixed before you try it out. But if you still want to play the game, you can do so and you will gain some satisfaction from it.


  • Erotic game based on Pokémon
  • Enjoyable gameplay
  • Good art design
  • Regular updates


  • Too many bugs
  • Limited customization options
  • Limited dialogue

Game Reviews

Man does it suck that Oppaimon has been abandoned! I came across this recently and I had never heard of it before. I knew that the game was not complete before I started playing, but being a huge fan of the series this is a parody of, I decided to see what it was like. Well, I kind of wish that I never played it. Not because it was not good and not a lot of fun, but because I had such a great time with it, I really wish that the developer was able to get this one over the finishing line.

Back To Generation One

As you have no doubt already figured out, Oppaimon is a lewd parody of the Pokémon games. There is certainly no shortage of lewd Pokémon games out there, but I think the fact that this one was inspired by the first generation of Pokémon and that the developer really wanted to make it so it was based on those original few games rather than the modern ones was a cool direction to take the game. I am more of an older Pokémon fan so any time there are references to the early days of the franchise, I get a kick out of it.

Yes, You Gotta Bang Them All

That is not me trying to be clever, Oppaimon flat out states this, only they use a bit of a stronger word than bang! Look, collecting and having sex with the Pokémon like characters is pretty much the goal of at least ¾ of the adult Pokémon games that are out there and this one is no different. We have come of age and now we must set out on our journey. The twist here is that after years and years of “breeding,” the Pokémon have basically evolved so that they are more humanoid and this is something I like. I enjoy Pokémon sex games, but I have no desire to see Squirtle getting railed!

They Had It All!

In basing Oppaimon on the first generation of Pokémon, we have a much more “simple” kind of RPG here. We need to explore the land, finding more Oppaimon that we can then use to fight others so that we can add them to our ranks. I like the top down retro Pokémon game style that is on offer here and I appreciate how simple and easy to understand the combat is. I can see why it may be a tad simple for some people, but I do think that old school Pokémon fans will appreciate the nod to the older games here. I just wish that there was more content! I was able to see pretty much all that was on offer here the first time I played it and it left me wanting more!

Hey, I Really Do Want To Bang Them All!

It is perhaps the art more than anything else that makes me bummed out that Oppaimon never got completed. What we have here are a bunch of sexy looking girls that are inspired by many of the Gen 1 Pokémon! There is an incredible selection of ladies here and I think that the bits of lewd content that are here are done very well. Even when they are clothed, they are very “scantily clad” so they look super hot here too. The gameplay stuff is all done in that classic Pokémon top down style and it just oozes charm.


Hey, I get that developers sometimes have to move on and that is what happened here, but it is a real shame. Oppaimon is a game that I had a lot of fun with and I would have played through the entire game if the developer had gotten it over that finishing line that was being held by Brock and Misty. Even though this is an abandoned game, if you are a Pokémon fan, especially the earlier generations, I highly recommend you give this a try.


  • I liked how it was based on Gen 1
  • The game has a lot of Pokémon themed humor which I enjoyed
  • It has some very impressive and sexy visuals
  • The gameplay may be basic, but I found it enjoyable


  • The game never got finished
  • Some have said they feel the combat and gameplay is a tad simple
