Fusion

One of the core mechanics of Cassette Beasts is fusion. The game has a fusion meter which accrues power every time the player takes damage in a battle. Once it is full, the player and their partner can fuse each of the monsters they play as into a combined form.

Gameplay

Fused monsters gain the moves of both monsters they are derived from, and have statistics based on the combined statistics of them. Therefore, they are immensely powerful. However, playing as one monster instead of two also means that only one move can be made per turn, and if the opponent has sufficient stats to deal significant damage, the player is at more risk of being hurt.

If the fusion takes fatal damage, it is dissolved and both of its components take fatal damage as well. After completing a battle, fusion is not maintained.

Fusion Power

Once the player reaches a certain relationship level with a partner, you can execute a special move called Fusion Power when you fuse with them. It deals an immense amount of damage, often killing your opponent's monster instantly or seriously harming them. Its exact nature depends on what monsters you have fused, coming in many varieties, such as Spike, Bomb, Sword, Axe, Wheel, Beam, Meteor, Wheel, and Smash.

Rogue Fusions

Additionally, there are also Rogue Fusions that exist in the wild. They are indicated by a black outline of a monster, and all look the same on the overworld regardless of the monsters fused.

• Fusion Swarms have several normal monsters that the player has to fight before the fusion. The fusion in these battles has a significantly higher chance of containing a bootleg monster.
• Unstable Fusions are fusions where one monster is Anathema, which appear after completing certain content in the Ranger Noticeboard.

* Orb Fusions are encased in an an orb which the player has to destroy. They appear after progressing further in the Ranger Noticeboard.

Story

Fusion is a mysterious phenomenon unique to New Wirral. It is hard to do, and even the Ranger Captains are impressed by the player's mastery of it. Post-game, the player discovers more about the origins of fusion when undertaking Helia's quest Here Comes The Sun.
