However, he is actually Akudaikan's creator and the true main antagonist of the series.
For most of the series, Goyan resembles a tiny frog/monkey-like elderly man with green skin, dressed in a traditional outfit with long white sleeves, red slit eyes, and sandals with socks. He also has a small tail. He normally poses as if he holds a cane.
In his true form he grows to gigantic size, has a longer tail, longer hair, bigger ears and a horn on his head. He is also very muscular and looks to be wearing a type of armor.
At first, he seems like a jovial old man and Akudaikan's most loyal servant. He is however proactive in scheming to defeat the Cures and archive his goals behind the scenes. He will sometimes cover for the other villains and even offer them advice on how to defeat the Cures but in a mocking way. He likes to openly taunt others and enjoys seeing them angry, which is evident in how he mocked Karehan during Karehan's attempts to defeat the Pretty Cure.
On the other hand, he sometimes tries to accommodate and understand his lackeys (who do not know his true power and often treat him with little respect), such as training with Kintoleski or letting Moerumba ramble on about dancing. His relationship with Ms. Shitataare seems closest, as she gave him the nickname "Gō-chan" and they both favor trickery when dealing with the Cures. However, they can also clash over this as Shitataare doesn't want him to get the upper hand and defeat the Cures first.Episode 30
His true goal is bent on the destruction of both earth and the Land of Fountains. In fact, he created Dark Fall just for this purpose.
Goya means Bitter Melon.
At first, he seems like he's just Akudaikaan's most powerful lackey and acts as his underling berating the other villains and at one point even reviving them to beat the Cures. In episode 29, he even manages to kidnap Flappy and Choppy to prevent the Cures from transforming.
After the Cures go to Dark Fall to confront Akudaikan in episode 47, it is revealed that he is the one who has created Akudaikan and the true villain using Dark Fall to destroy the fountains. After killing Akudaikan, he reveals his true form but is eventually defeated by Pretty Cure's Spiral Heart Splash Star in the final episode.
- He is the first main villain who is the man behind the curtain, although technically, Baldez could be considered the first.
- His and the other main villains' silhouette (Evil King, Desperaia, the Boss, Moebius, and Dune) are seen in Pretty Cure All Stars DX 3: Mirai ni Todoke! Sekai wo Tsunagu☆Niji-Iro no Hana. Goyan's silhouette represents Dark Fall.
- He shares the same voice actor with Black Fang, the main antagonist in the movie Happiness Charge Pretty Cure!: Ningyou no Kuni no Ballerina.
- Goyan returns in Pretty Cure All Stars: Minna de Utau♪ Kiseki no Mahou! as one of the revived villains.
- He is very similar in his concept, character development, and appearance in his final form, to Baldez from the previous season, who, like Goyan, revealed himself to be the main villain in the last few episodes of that season.
- Ms. Shitataare calls him "Gō-chan", much to his annoyance.
