Pokémon Infinite Fusion Guide: How to Play, Tiers, and Download

Have you played every Pokemon game? Have you seen every evolution? If you have, congratulations because that’s a lot of time and effort. Did you know there’s a game with over 176,000 Pokemon? Whether you’re looking for new Pokemon territory to blaze or fancy yourself a mad scientist, there’s a fanmade Pokemon game for you. There is a catch, though, as you must have your own copy of Pokemon FireRed.

Pokemon Infinite Fusion from developer Schromms dropped in 2015. Since then, it’s had four versions and many updates. It’s still played and kept up to date with the last update to fix some bugs occurring in 2022. It’s considered a modification to Pokemon FireRed, so the original game is required. This fangame is just one of many that have impressed players looking for something outside the main games series. While some of these games have exciting new stories or player customizations, this one has it’s own draw, and it’s a massive one.

Origins of Fusion

The game focuses on the DNA Splicers, which were introduced in Pokémon Black 2 and White 2, released in 2012. In those games, Team Plasma wants the Splicer for their own diabolical means and eventually do get ahold of it. They pass it on to the antagonist of that game, Ghetsis. When the player faces Ghetsis in the Giant Chasm, he uses it to fuse the Legendary Pokemon Kyurem with Rehsiram/ Zekrom. The result is a new Pokemon, Black Kyurem or White Kyurem, depending on the game’s version. 

Fusing the Legendaries makes an even more powerful Pokemon. Eventually, players also gets this opportunity to create a new Legendary if they have a DNA Splicer. Alternatively, players can use the Splicer to reverse the fusion and receive both original Legendaries instead. These were the only options and occurrence of fusing or splicing Pokemon together until a fan decided to change that. 

Infinite Fusion

Infinite Fusion is essentially Pokemon FireRed with the significant addition of, as the title says, “infinite fusions” of Pokemon. You can splice together every Pokemon with any other Pokemon in the game. The game has every Pokemon from Generation 1 and Generation 2 plus 101 from Generation 3 to 7. That makes the total base Pokedex 420 Pokemon deep, with over 176,000 combinations to create new Pokemon. These options aren’t available in any of the official main Pokemon games. Actually, there isn’t this much freedom in any other Pokemon games when it comes to crafting your unique team. 

When Pokemon are fused, it’s not just their likeness that changes, but their stats, move set, abilities, and entry in the Pokedex. Members of the Pokemon community crafted the sprites that go along with these unique creations, with over 50,000 in existence in the game. Not every Pokemon currently has a completely unique sprite image, but their other factors can change.

New Looks

When two Pokemon are fused, a formula determines what they will look like. One Pokemon is the head, and one is the body, meaning there can be two different versions of those two Pokemon visually. The stats, strengths, and other options will change accordingly as well. The head choice Pokemon determines the cry, pattern, and color of the new creation. 

After fusing two Pokemon, you can’t fuse the result again with another Pokemon. A Pokemon can only be fused to one other Pokemon or unfused, reverting the two base Pokemon back to their original selves. Pokemon with the same species can be fused for an XP gain, but the stats will stay the same as the original base Pokemon. At the end of the game, 19 triple fusions can be performed to combine trios, combinations of the starters, or three Legendaries.

Fusion Tiers

In a game with over 176,000 choices, it’s good to get an idea of some of the best options to aim for. Not every Pokemon combination is something you want to see, and not every variety will be worth the effort when it comes to battling, either. Some are just fun to experiment with or challenge yourself to find and try to put together. Here are a few examples of how these fusions break down regarding quality and looks based on averages from surveys of players.

Fusing Process

To fuse a Pokemon, you will need one of four items. These items can generally be acquired for a price from Pokemarts. Usually, they can only be used once before they are destroyed. 

  • DNA Splicers – Fuse and unfuse Pokemon, but are destroyed after use. $300 at the Pokemart.
  • Super Splicers – A better DNA Splicer that is destroyed after use. $ 1,000 at the Pokemart and four badges earned.
  • Infinite Splicers – This is a regular DNA Splicer that is never destroyed. You’ll need to beat the robot inside the Cinnabar laboratory to get one.
  • DNA Reverser – This only switches an existing fusion back to the original Pokemon. This item is $300 from the Pokemart after earning the first badge.

After you have your DNA Splicing item, you can begin fusing with any of your Pokemon. Before you go through with the process, you’ll get a preview of what they’ll become unless you haven’t seen them yet. In that case, you’ll only get a silhouette of the new Pokemon. This preview is your chance to decide which Pokemon to use for the body and head and whether what you’re about to create will be cute, scary, or grotesque.

Building A Monster

Once you’ve fused your two or three Pokemon together, you can further customize it. You can name it and then pick its moves using the currently available moves to the base Pokemon. You get a random nature, but you can choose your own by traveling to Cinnabar Island, using Surf to get another island, and speaking to an NPC. You can also teach moves to the Pokemon later from either of the originals using Move Reminder in Pokemon Centers.

The special Ability that all Pokemon have is also a choice when fusing. You can choose between two Abilities, one from each origin Pokemon. The options that will appear are the head’s second Ability and the body’s first Ability. 

It gets a bit more complicated when it comes to identifying the Pokedex entry. Since a single Pokemon can have a dozen different creation results that all fall under the same name combination, there must be a way to differentiate. This method uses the Pokemon Head name/Body when speaking about the species and the Head Number/ Body number to identify the Pokemon creation.

What Else is Different?

On top of the new Pokemon, there are also a few changes to keep the story interesting. You will explore Kanto and Johto, face off against Team Rocket, defeat 16 gym leaders, and battle the Elite Four. While this is all part of the original game, there are a few updates to make it more challenging.


There are multiple Modes to play the game in, altering the Pokemon that you encounter in the wild. In classic Mode (recommended for the first playthrough), you’ll face the standard Pokemon in the wild. In the Modern Mode, you’ll face different Pokemon, creating unique encounters and a fresh experience. 

The trainers and gym leaders are also different in Modern Mode. The trainers have a separate team from the Classic Mode, and these can include Pokemon fusions. These fusions will also up the difficulty level. The gym leaders will switch specialties, and the trainers inside the gyms will all change to match the new type focus.

There is a third Randomized Mode that can make the game even more varied with each playthrough. This mode allows players to select which areas of the game they want randomized for this playthrough. 

Randomized Mode Options:

  • Trainers
  • Gym type
  • Starters
  • Wild Pokemon
  • Maps
  • Legendary 
  • Wild fusion encounters
  • TMs and Items

NPC Update

Adding to the difficulty, there is also an update to the way NPCs behave in Infinite Fusion. Rather than beating an NPC and not being able to interact with them, the NPCs become more fascinating. Once you defeat an NPC, you can trade with them or strike up a rematch. Each time, the rematch will be more challenging, including evolved versions of previous Pokemon used in battle.

Once you conquer the entire Kanto and Johto regions and defeat their gym leaders, there’s more to explore. You can go further into the Johto region and see the area like never before. After beating the main game, there’s also the option to explore the Sevii Islands and find more exotic Pokemon to catch and combine. Don’t forget to seek out the 25 Legendary Pokemon, all of which can be fused, of course, and embark on more than 40 side quests. If you’re tired of playing alone, there is an online trading and battling system to share your creations and test your strategy.
