Unit-01 Eats the S² Engine

After its external power expires, Unit-01 reactivates on its own, devours Zeruel, and absorbs the Angel’s S² Engine—removing its previous energy limit.

A constrained system uses an encounter with a stronger system to acquire the resource that made it dependent on operators, becoming harder to shut down and qualitatively more autonomous.

Unit-01 is a living being containing Yui Ikari’s soul; its behavior is protective as well as power-seeking.
