Evangelion Mark.04B

Evangelion Mark.04B is an autonomous Nemesis Series unit from Evangelion: 3.0 You Can (Not) Redo, planted as a hidden failsafe on the Tesseract that holds Evangelion Unit-01. It waits disguised as a cuboid box until WILLE's Operation US forces it to reveal itself.

Once active, the box unravels into four long metallic threads able to reshape themselves freely. A single core rides inside a compact block resembling the Mark.04A's main body, and that block races along the threads at speed to stay out of harm's way. The unit carries two shoulder pylons in purple and light green, while the main body is a black oval disc with the core half-exposed underneath and rings of holes across both faces.

The Mark.04B weaponizes light itself. By rearranging its threads it reflects and focuses energy into cross-shaped lasers and detonations that A.T. Fields cannot nullify, shifting to a new thread configuration for each attack. During the orbital battle it opens fire the moment Asuka takes hold of the Tesseract, its first laser searing off part of Unit-02'β's shoulder armor. The mobile core block keeps sliding beyond reach while an atom-like thread formation rains explosions onto the crippled unit. Ordered by Misato to keep guiding the container toward Earth, Asuka screams for Shinji to do something; a fissure opens in the Tesseract and Unit-01 fires a beam from its eye that bursts the core block, consuming the drone in a cross-shaped blast before the container drops into the atmosphere. Its final appearance comes in Evangelion: 3.0+1.0 Thrice Upon A Time, wiped away with all other Evangelion units by Gendo's Spear of Gaius.

Nothing living crews the Mark.04B. WILLE catalogs the unit under the name Code 04B, and its wavelength registers as "approximately blue" on operator displays instead of a full Angel signature. Hideaki Anno's early rough for the design classified it as an Angel rather than an Evangelion, and on destruction it produces the cross of light and rainbow halo seen when other Evangelions die.
