Players who reach S-Class in Super Power Fighting Simulator unlock the Fusion upgrade option in the Upgrade menu.
Fusions provide players with a permanent multiplier that stacks with other multipliers in-game.
In exchange for the multiplier, the player's rank and stats are reset to F-Class and to 0 Power respectively. However, they retain the stat multipliers and the reputation they had before the fusion. As a result, players gain stats at a significantly faster rate. Players also unlock a transformation for every fusion they have fused with. In certain fusions such as Gryphon, players will also unlock a new dimension.
Together with the increase of the multiplier, fusing will increase the number of gems a player gains each minute.
When a player fuses, a blue server-wide announcement in the chat window appears in the following format:

Trivia[]
- The multiplier for each fusion increases by x20 or x25 times from the previous one, except between Reaper and Dragon, where the multiplier increases by 100.
- The biggest gap in power requirement between two fusions is x16B (Reaper → Dragon), while the smallest gap is ~x23K (Gryphon → Phoenix).
- The biggest gap in power requirement between a fusion and the required class is x30K (Ruler of Time → Dragon), while the smallest gap is x750 (SSS-Class → Gryphon), making therefore Gryphon the easiest fusion to obtain, and Dragon the hardest one.
- The biggest gap in power requirement between a fusion and the next class is x62.5K (Dragon → Universe Ruler), while the smallest gap is x6 (Yeti → Z-Class).
