Merge Monsters: Fusion Battle is a free-to-play game developed by FALCON GLOBAL and is available on Android. It is a merging game that follows the same gameplay as Dino Merge, Dragon Merge, Superhero Merge, and others. However, it has a unique twist to it that sets it apart from the others.

In Merge Monsters: Fusion Battle, you merge the same animals or warriors to create stronger monsters. The game features a variety of monsters, animals, or plants that you can combine to create newer, more special, more powerful, and amazing creatures such as Siren head, Hogie waggy, Pissy, Mommy Monster long legs, Toys Factory's Monster, Spider Long Legs, Daddy Long Legs, Baby in yellow, and more.

The game has a blending of horror survival style with a familiar merge master game, which makes it funny, challenging, and addictive. The monster's assault and defense get more powerful as it levels up. You need to be quick to react and think to unlock the new animals or warriors and create successful Blue Monster, Pinky Monster, Hogie waggy, Pissy, Mommy Monster long legs, Freaddyy teddy bear, Spider Long Legs, Daddy Long Legs, and more.
