J.P. Shibayama (柴山 純平 Shibayama Junpei?) is a main character in the Digimon anime series Digimon Frontier. He is one of the "DigiDestined", children who were chosen to receive the ability to transform into Digimon in order to save the Digital World.


J.P. is a young, overweight boy with spiky brown hair and eyes. He wears an orange shirt under a blue jumpsuit with yellow pockets, white socks, and blue and yellow sneakers.


J.P. is the oldest member of the group, and was the one who was chosen to wield the Spirits of Thunder. This allows J.P. to use AncientBeetlemon's power to turn into two Digimon forms which use mainly electricity attacks.

At the start of the series, J.P. shows some jealousy towards Takuya Kanbara, the main character of this series for being Tommy Himi's hero and being able to combine both of his Digimon forms into one more powerful form. He also shows feelings for Zoe Orimoto, the only female of the group. Though his interest in Zoe is seemingly not returned, they do become closer as the series progresses. J.P. also seems to have a hidden fear of being alone—despite being constantly surrounded by people when he was in the Real World, he felt that he had never really been anyone's real friend. This fear spawned some rather obnoxious behavior in the earlier parts of the series. As the series progresses, J.P. learns to confront his fears, and begins to see the other members of the group as real friends. He also overcomes the jealousy he feels towards Takuya.

J.P. is good at performing magic tricks, with which he used to try to appeal to his classmates in the Real World. Alone But Never Alone In the Digital World, he uses his tricks to cheer up the other DigiDestined, his first real friends. He is also good at math and has a talent for engineering, which he uses to make complicated plans to build a raft The Swiss Family Digimon and a giant slingshot The Man In The Moon Is You.

Early on in the series, it is revealed that J.P. is afraid of thunder, making it ironic that all of his Spirits are of the electric type. The Odd One Out
