Zeruel smashed threw all of NERV's defenses. It defeated Units-00 and Unit-02, and got right to Central Dogma's front door before Unit-01 stopped it.
With its whip-blades, it was able to slice up Asuka's Unit-02, and take off its head and arms. Its AT Field and armor was also strong enough to withstand Unit-00's attack with an N2 bomb. It even blew off Unit-01 's arm, but it did not finish it off before it went Berserker.
Profile: The Fourteenth Angel was pure strength; it had sharp, whip-blades for arms and shot energy blasts from its mouth.
Fate: Shinji and Unit-01 ripped Zeruel apart in it's Berserker mode; Unit-01 finished the fourteenth Angel off by eating it and its S2 Engein (which made the Eva fully operational without any outside electrical energy source and it allowed the Unit to grow to its fullest potential as a weapon and part Angel). One of Zeruel's whip blades was ripped off and attached as Eva-01's left arm.
Notes: Zeruel is the patron Angel of Might.
