Bagoo (バクウ Bakuu), appearing in Klonoa: Empire of Dreams, is the adviser of Emperor Jillius. Bagoo is the minister who accompanies Jillius as they charge Klonoa of disobeying the imperial law of not dreaming. In the end, it's revealed that Bagoo is the cause of Jillius' chronic insomnia, and he is actually the King of Despair (ぜつぼうの魔王 Zetsubou no Maou).
After Klonoa defeats Jillius in battle, the wounded emperor reveals that he was the one that left several clues in the form of the dreams that the people who turned into monsters had. Bagoo then reveals himself and states that he is the one behind the monsters in the kingdom. His plan is to steal everyone's dreams and transform them into monsters, creating his very own kingdom in the process. During this, his shadow assumes his true monstrous form and peels itself off of the floor behind him. He announces that he shall transform Klonoa and Huepow into monsters as well, prompting them to engage him in battle.
Bagoo's true form is a large dragon-like beast with a body made completely out of a grey ooze that wears a horned mask. The mask comes in three different colors and expressions, and can continually rotate itself to change. The colors/emotions are red (anger), yellow (joy), and blue (sorrow). Bagoo's weak point is his heart, which is shown to be a spinning, white sun-shaped symbol.
In Klonoa Beach Volleyball, Bagoo has a cameo appearance in Tat's ending. Instead of being scared of Leorina and Tat attempting to steal his money, the evil minister burst with laughter when he saw that Leorina's face was painted in Tat's vertical black and white pattern as part of a lost bet.
