Popee once had a really short temper, jealous, and insane personality throughout the show. He wants to be better than everyone else in the circus, as proven by showing acts of jealousy, for example, toward Papi when he was able to complete a trick that Popee was not able to do successfully. It's the same with Kedamono, who suffers the most from his violent outbursts. However, despite the violence he directs towards him, Popee does not actually hate Kedamono. In fact, he feels less alone when near Kedamono. Popee is self-centered, but he is also lonely. The reason Popee misbehaves and treats others the way he does is because of jealousy. Despite his behavior towards others, Popee appears to be fond of his sister, Marifa. He apparently is unaware of her true, devilish nature and thinks she is without fault. It's possible they aren't blood-related. Popee is described as a "fast-paced runaway type who will do anything to protect himself. He's as simple as a child, and to say he's innocent is an understatement." Popee seems to get frustrated often. In a tweet, Ryuji Masuda noted that, in Japan, people have a fear that they won't be loved if they don't get good results or high achievements, and that this creates much fear and anxiety. He says this is how Popee feels, as well, except that his frustration and fear become insanity. Sometimes, Popee gets so caught up in himself that he self-destructs. Popee is very prone to loneliness, as can be seen as well as many other instances where Popee seems to avoid any situation that involves being left on his own. While it has been officially stated that his biggest fear is 'indifference' on others' part. After 13 years in being in the Wolf Zirkus realizing that there was no live audience in the desert, he left the circus and went on to be one of the most renowned scientists in Japan.

OTHER CHARACTERS:

Papi: Papi (パピィ) is the tritagonist of the series. He is a senior clown and the leader of Wolf Circus, a travelling performer and the Father of Popee and Marifa. His age is 59. Papi has a muscular body and wears a yellow and orange skin-tight harlequin outfit with a purple fringe and fancy white gloves. He also sports a removable sun-shaped headpiece (which "puffs" up when very mad, and it also can be used as a weapon of sorts, like a shuriken) and an impressive, emotive mustache. Papi had hair when he was younger, but he may be bald now. He is a flamboyant individual, opposite to his son. Unlike his son, Papi seems to genuinely care about both Popee and Kedamono. Papi is quite expressive. Papi is dedicated to improving Popee's clowning performances, though his lessons are often extreme and unorthodox. Papi was thought up as a character with both paternal and maternal qualities. Ryuji Masuda explained on twitter that the difference between the two is that maternity is the power to "produce and affirm", and is characterized by unconditional love. On the other hand, paternity, according to Masuda, is the power to "choose and move", and is characterized by weighing the negatives and positives and then making a decision, or judgement.[7] Papi accepts both the negatives and positives of those he loves, which is why his son, Popee, doesn't shy away from jealousy or envy (or other negative feelings), which typically leads to destruction. With his paternal side, Papi believes Popee has a long way to go...but with his maternal side, he also thinks that Popee's very cute. In the episode「SLEEP」, when Kedamono winds a music box to help Popee sleep, Papi's maternal instincts kick in as he tries to feed Popee with a bottle. He becomes very upset when Popee proceeds to smack the bottle from his hands, shattering it when it hits the ground. Papi is very dedicated to and takes good care of his elephant car, Paola, and becomes vengeful whenever Popee defaces her. Papi also seems to have a good relationship with Alien, interacting with them casually where Popee and Kedamono are more wary to. Wakako Masuda referenced Sigmund Freud's personality theory while addressing questions about Papi. She refers to Papi as a portrayal of the super-ego: the rigid, controlling part of one's identity that represses desires in order to conform to expectations.[9] His conflicts with Popee can be further explained by the way the super-ego naturally clashes with the mediator ego.

Kedamono: Kedamono (ケダモノ lit. beast) is Popee's "assistant" and a performer at Wolf Circus. He is a deuteragonist who is a constant victim to Popee's torment. Kedamono was picked up by Popee and Papi as a puppy (try saying that three times!) before joining the circus. Before that, he was part of a temple. He is shown in the manga as a puppy while Popee is still a baby, yet he is also 8 years older than Popee. Kedamono seems to the kindest and most caring of every character, showing his concern every time someone was injured, or when something was destroyed. Though, if offered a chicken leg, he forgets his morals and will do almost anything to have it. He also appears to have an egotistical streak of his own—despite it not nearly rivaling Popee's—as he has unwisely goaded Popee on during shows of skill. Though his patience (especially concerning Popee) is considerable, he has several moments of bitterness and unwillingness to help Popee, possibly due to the foul treatment Popee tends to put him through. Kedamono wears a mask because he's afraid of exposing his true nature, which is that of a "beast" (this may literally mean he's disguising himself as a human with his mask, and he's disguising his true nature as a wolf). Even he doesn't exactly know what it is, though, and that scares him. This could explain his obsession with food. There are times when this can be seen in the show, such as in「ESCAPE SHOW」when Alien destroys the fried chicken he had used to get Kedamono to inject Popee. His mask becomes very different, with color and rather scary expressions. The reason Kedamono follows Popee is because Popee, as self-absorbed as he is, doesn't care to look further than Kedamono's mask. He has no interest in what or who Kedamono really is, and feels that, ultimately, Kedamono is just Kedamono. Even when Kedamono's nature occasionally rears it's head, Popee doesn't look very deep into it, which makes Kedamono relieved, and makes him feel safe to be around.[8] Kedamono also sticks by him because, while he appreciates Popee for being shallow, he also recognizes that Popee is lonely, and doesn't want him to feel that way. In wearing the mask, Kedamono is intentionally disguising himself as a human, and disguising the fact that he is a wolf. The thing is, of course, is that everyone knows he's an animal wearing a mask—though it's possible they're unable to tell what he is, exactly. Popee doesn't treat Kedamono like an animal, though—he instead treats him like a creature with a mask that's pretending to be human, which is exactly what Kedamono is. At the same time, he will treat him as an animal or human when the situation calls for it. To an extent, it seems that Kedamono admires Popee's ability to unapologetically be himself. Wakako Masuda said, on twitter, that Kedamono feels that, in trying to be human, he could be more like Popee, and complement him better. Make him stand out more, which is what he wants. What he didn't account for is that he's more skilled than Popee is. Now, he can't be human—but he can't go back to being a wolf, either. At the end, Kedamono leaves Wolf Zirkus. He left because he was afraid that the fact he's a wolf would be exposed, and the contempt for himself he buried deep for trying to be human, when he's an animal. It's unknown whether he was able to return to living as a wolf afterwards, and he returns with his son, Kedamono Jr.

Marifa: Marifa is Popee's younger sister, though it is possible they are not related by blood. She only exists outside of the televised world. She is 23 years old, and appears to be a performer like the rest of her family. She is a trickster, and "probably" a girl. While her family lives at the circus, she lives in a city. Marifa has gray/silver hair and green eyes. She wears a blue hat decorated with two pink panda faces on either side of her head, a light mint dress with pink frills on the sleeves and the hemline of the dress with a pink collar and two small pompoms on the middle, purple stockings, and blue boots with lavender soles and pink brims. She also wears a blue tail with a pink pom pom on the end, in similar fashion to her older brother. She seems to also wear a light lavender shirt under the dress and blue wrist-length gloves with pink cuffs.
