Sachiel first appeared out of the ocean, coming ashore just east of Tokyo-3. The JSSDF tried to stop Sachiel's advance, sending in a force of tanks and Heavy Fighter Jet-VTOL craft, but they fail miserably. The JSSDF eventually used their "last resort" by luring Sachiel to a mountain, and then detonating a planted N² Mine underneath its feet. This results in considerable damage to Sachiel, melting some 18% of its mass, but it is only a matter of hours before it regenerates the damage. In the process of regenerating from the N² Mine attack, Sachiel's original bony "face" structure is pushed towards the upper right of its torso as a new slightly more rounded bony "face" grows from the center of its chest. While this fails to stop Sachiel, it does slow down the Angel long enough for Nerv to prepare Evangelion Unit-01 to be sent into combat against Sachiel. Finally, Eva-01 was launched against Sachiel, but the Eva promptly fell flat on its face. Sachiel then grabbed Eva by the head, and broke its left arm. While holding Eva-01 by the head, Sachiel then shot out its energy lance from its palm, impaling Eva-01's head and flinging it against a building. However, Eva-01 then went into "berserker" mode, making a somersaulting drop-kick against Sachiel ending in Eva-01 ripping off half of Sachiel's ossified face. Realizing it was on the verge of defeat, Sachiel once more adapted itself to give its body a whip-like consistently then jumped onto Eva-01, wrapped itself around the Eva, and self-destructed. However, even this self-sacrificial attack failed to destroy Eva-01, which emerged from the destruction with only moderate damage.
