Deidara no Mikoto (デイダラの美琴) was the Kami of the Shores. He was a Student of Onoki.
Deidara had slanted blue eyes and very long blond hair which he wore drawn into a half ponytail with the rest hanging down freely. Under his cloak, he wore a V-neck, sleeveless, midriff shirt with mesh armour underneath it along with pants, stirrups, and sandals.
Deidara usually showed a cool, and relaxed attitude, never losing his smirk even while fighting an intense battle or when being blamed by his partner. Deidara's partnership with his second partner, Tobi, however, was very different. Tobi apparently held a great respect for Deidara, and frequently called him "senpai" (先輩, senior).
During his time as an Iwagakure shinobi, Deidara was a pupil under the Third Tsuchikage: Ōnoki. He possessed the Explosion Release kekkei genkai which enabled him to become a member of the Explosion Corps. Deidara's exploits eventually caught the attention of the Kami and Susanoo Uzumaki were sent to recruit him. Deidara refused at first until he accepts as a chilf of the Legendary Trio of the Eight Paths. However, Deidara was easily defeated by Utakata's Bubble that traps his hands and begrudgingly joined the Wanderer. In the anime (Naruto Shippuden), Deidara left Iwagakure in shambles by visiting several structures in the village.
