These cube craft paper toys are Amaimon (aka Earth King) and Mephisto Pheles, based on the manga Ao no Exorcist (Blue Exorcist), the papercraft was created by alonso jacobo. Amaimon is one of the 8 Demon Princes of Gehenna and a son of Satan. Unlike his father and elder brother Mephisto Pheles, Amaimon had little interest in Rin after their first encounter, but his interest grows during his multiple encounters with Rin. It is revealed in chapter 39 that he is Gehenna's seventh man of power.
He appears to be calm and collected, but very confident in his powers. Very brash and doesn't seem to be seen in a bad mood. However, he shows great anger and annoyance when someone gets in the way of his fun, like when Mephisto intervened with his fight against Rin in the Chuchi forest. He also does not take losing very well when he is defeated by Rin and reverts to his demon form to confront Rin once again, during the hearing against Mephisto. He is very playful and doesn't take things seriously when it comes to fighting strong combatants which hints that he is either ignorant, or hideously skilled in combat. He has also been shown to care for his familiar, Behemoth, which he shows great distress over when Kirigakure Shura kills it.
Amaimon's host is a teenage boy. He has a spike of hair which is lightly colored compared to the rest of his dark green hair. He wears a jacket that has cross bones as buttons. He also wears green arm warmers and a black and pink short sleeved shirt under his jacket which is ripped at the ends. When he is in his demon form he has arms like his familiar, Behemoth, which are muscular and green. He also dons the long ears and a tail that resembles an alligator. He is of average stature at 172 cm (5'7"). He appears to look like a 17 year old boy but his real age hasn't been shown yet.
Mephisto Pheles is the Principal of True Cross Academy and also an Exorcist. He uses the name Johann Faust V in public. After Shirō Fujimoto's death, Pheles was ordered to execute Rin Okumura, however he accepted Rin's proposal in becoming an Exorcist and entered him into True Cross Academy as a student. He is the son of Satan along with his brother, the Earth King, Amaimon. It was recently revealed that Mephisto is the King of Time, one of the Eight Demon Kings. He is second in Gehenna's hierarchy, right below Satan. His true name is Samael.
Shrouded in mystery, one quickly learns of Mephisto's innate ability to act as if he knows more than what he is letting on. Careful and meticulous, he is like a chess player, always ahead of the game.
He also enjoys chaos, as he stated to himself that he was a hell-raiser, and Assiah to be his playground, though he does not wish to see anyone get killed, claiming that he himself would kill Amaimon if he ever tried to kill any of his students. However when Mephisto first meets Amaimon in the series, it is implyed he is conspiring with Satan and is most likely training Rin on his orders. He likes to make gambles with whoever possible, including Fujimoto, Rin, and the True Cross Order.
He is prone to eccentric moments nestled in between serious moments, making light of a heavy mood and is portrayed as a man with more money than sense, but is very cheap when it comes to spending on others. Like his brother he loves to eat sweets and he is deeply interested in the Japanese pop culture, proudly stating that he is an otaku.
He wears an elegant white outfit which also includes a cloak and a huge hat, and has pointed demon ears and sharp, pointed teeth. He is also tall, having a height of 195 cm (6'4"). He has dark purple hair and forest green eyes. His normal clothes consist of a white top hat with pink and purple around the base, purple gloves, a tie that is pink with white dots, a white suit-shirt and undershirt, jester-style pants, and pointed shoes. His appearance prompts Rin to refer to him as 'the Clown'. As the series progresses, he stops wearing the jester pants and pointed shoes, instead wearing white dress pants and black shoes.
In addition, he can transform into a small white dog when he counts down from three in German. In this form he is a small, fluffy, Scottish terrier-looking dog with a large pink ribbon around his neck with a silver trinket attached to it, the trinket being the symbol of an exorcist.
