Real World

Lucid Adventure


Yopi is generally very laid back and very hippy like in his behavior, but he gets serious when citizens of his country are threatened.

He admittedly likes low rent stuff (Cheap and low in quality). He expressed the desire to conquer Lucid Adventure when facing against Sam Han. It was revealed that he holds resentment towards the Gods who he saw werent managing but rather using humans like puppets. His goal was to take the power of God and grant it back to the world in bits. He believes the power of God should be given to humanity meaning the humans can decide and rule the world of Lucid Adventure thus giving him a chance to rule it eventually

"What kind of a freak are you?" Nightmare Yopi


Yopi has not been seen in combat, but as the King of Yopi Land, it is safe to assume he is strong. His implied threats were enough to put Giga's Diplomatic Corps that included the Master Magician Light on alert. According to Roy Han, a battle between him and Sam Han would cause the end of Lucid Adventure
