Pokémon Infinite Fusion is a fan-made game that blends classic Pokémon mechanics with an exciting fusion system, letting players combine two Pokémon into unique hybrids. But like any Pokémon-style RPG, there are moments—grinding, walking long distances, or battling low-level wild Pokémon—where things can start to feel a bit slow.
The Speed Up Button is a built-in feature in Pokémon Infinite Fusion that dramatically increases the game’s speed, making battles, overworld movement, and animations go much faster. It’s a quality-of-life feature that many veteran players rely on to save time and speed through repetitive parts of the game.
It’s especially useful for:
Level grinding and training fused Pokémon.
Hatching eggs faster.
Quickly backtracking through areas.
Skipping long battle animations.
Speedrunning or replays.
How to Use the Speed Up Button
Using the speed-up function is easy. By default:
Press and hold the Alt key (on most versions) to activate the speed-up mode.
In some versions or custom builds, the speed-up button may be mapped to another key like Tab or Space, depending on your emulator or configuration.
You can also remap keys through the Options menu if the default doesn’t work for you. If you're playing the full Pokémon Infinite Fusion game (not just the web generator), this feature is available out of the box—no mods or extras needed.
Pro Tip:
Speed-up mode is toggleable in some versions (press once to turn on, again to turn off) and hold-to-speed-up in others. Check your game settings to be sure.
