Oncha Egg


Oncha Egg

Join Eggventure to receive an OnCha-Egg. In OnCha Monster World, the journey begins with finding an OnCha-Egg, hatching it, and evolving your monster from game to game. Trainers discover powerful new monsters, then upgrade and strengthen them to improve their chances of winning mysterious treasures. It's a world brimming with exciting monster discoveries and growth.


The quest to discover an Oncha-egg starts with Eggventure. As a found monster egg continues to thrive and absorb more natural power, its rarity level increases over time during gameplay.


When a Monster Egg is born in the expansive OnChaVerse, it possesses a single nature element. There are a total of four unique natural elements to uncover, making it a diverse and exciting world waiting to be explored.
