"An Angel's Invasion" (Lilliputian Hitcher) - Neon Genesis Evangelion S01E13 | Cartoon Cabal 13

The pilots are undergoing a synchronization test directed by Ritsuko deep within NERV headquarters when a new Angel, Ireul, appears within the base itself, being initially mistaken for corrosion. This Angel is actually a collection of millions of microscopic organisms, which interact to create a living biological computer circuit. Iruel infects NERV's computer network, and then infiltrates two of the three Magi supercomputers that control the base before Ritsuko is able to set up a firewall to slow its advance. Iruel is trying to trigger the NERV base's self-destruct, which requires a unanimous vote by all three supercomputers. Although Ritsuko's firewall slowed the advance of Iruel's infiltration, it is gradually taking over the last supercomputer. Ritsuko comes up with a scheme to use the Angel's rapid adaptive ability against it and force it to evolve in to a benign state, but must race to implement it before the Angel gains control.Episode description: https://evangelion.fandom.com/
