File No. 083 1st-Generation Sentinels 第一世代機兵

Specializing in close combat, these are the oldest models of all the Sentinels. The three Sentinels of this generation are No.10, No.11, and No.12.

The pilot of each respective sentinel during the final battle was Nenji Ogata in No.10, Ei Sekigahara in No.11, and Takatoshi Hijiyama in No.12.

Sentinel No.12 originally belonged to Tsukasa Okino, but he hid it in the ocean of Sector 5 so that Morimura and the others wouldn't find and retrieve it. In case something happened to him, Okino registered Hijiyama as its pilot.
