Pokemon Infinite Fusion Calculator is a tool that allows players to combine two Pokemon species and calculate the stats of the resulting hybrid Pokemon.

Pokemon Infinite Fusion is a fan-made game that allows players to fuse two different Pokemon species into a unique hybrid Pokemon. The game features a vast number of fusion combinations, with over 175,000 possible fusions. Here are some key features of Pokemon Infinite Fusion:

- Ability: A fused Pokemon has access to its body's first ability or its head's second ability. If a Pokemon currently has a hidden ability, that ability is shown instead.

- Experience: The fusion's total experience will be the same as the first selected Pokemon's experience, rounded down to the nearest level. Each fusion uses the fastest experience progression, so having the same experience total may result in a higher level Pokemon. A fusion will not be lower level than either of its halves.

- Moves: A fusion learns all of the moves either half would learn, according to the Black/White movesets. Some Fairy-types have Fairy attacks added to their movepools, and the Starters all use their 3rd gen movesets instead when they are part of a fusion.

- Items: Items that provide bonuses to specific Pokemon can be used by fusions if that Pokemon is the body of the fusion.

- Sprites: The game uses a multitude of community-created fusion sprites to give many of the fused creatures a wholly unique design.

To perform a fusion, players need to purchase DNA Splicers from the PokeMart. When fusing two Pokemon, players will get to choose between two new forms with one base Pokemon acting as the head and the other as the body, combining the two Pokemon's typing. The game includes all the features of the original Pokemon FireRed game, such as battles, trading, gym battles, and the story. However, the game also includes new features that are unique to Pokemon Infinite Fusion, such as fusing with NPCs and wild Pokemon. Players can use their new hybrid Pokemon to battle against other trainers and gym leaders.
