Popeye

He is 1.65 cm tall. He is blond and has dark blue eyes. He wears a pink and white striped full-body suit with a long cat tail, along with a pink bunny hat and a light blue bag, he has long hair if he takes off the hat.

Popee, despite proving to be affectionate with his loved ones, has a very bad temper and is quite competitive due to his jealousy.

He wants to be the best in the circus. He often has jealous and angry outbursts when other characters manage to complete a trick that he doesn't or prove to be superior, most of the time being aggressive towards Kedamono. The creator confirmed that Popee doesn't actually hate Kedamono, he just takes it out on him.

Due to his competitive attitude, he often involves those around him and self-destructs.

Ryuji Masuda said in a tweet that most modern Japanese people fear not producing satisfactory results and therefore not being loved, Popee feels the same and that's why he gets frustrated with himself, only in his case he turns fear into madness.

Despite his nature, he loves his younger sister, Marifa. He is unaware of his sister's true nature and believes that she is incapable of doing anything wrong.

He doesn't have a good relationship with his father, Papi, because he believes he is not his real father. Kedamono and Papi try to help Popee with the tricks but he rejects their help.

He is affectionate, mischievous and quite proud of himself, his character is unstable and he is very temperamental, but as previously said, he knows when to support someone when it is needed.
