In the core storyline of Hero: 108, humans and animals lived together in harmony until High Roller, a malicious character, was unceremoniously banished from the Eastern Capital.
High Roller grudgingly wandered the Hidden Lands and developed a deep hatred for those who cast him out. Fate, often a playful catalyst, intervened and High Roller was struck by lightning - in turn bestowing him with the amazing ability to speak to animals.
With his new powers, High Roller brainwashed his new furry friends into believing that humans are evil - and began his plans to take revenge on those who exiled him.
But in the midst of the darkness, an alliance of Humans and clear-headed Animals sought to battle High Roller's armies and restore peace to the Hidden Lands. These heroes called themselves Big Green!
