Shateiel

Shateiel (シャテイエル) is a conceptual Angel which was never used, only appearing in Neon Genesis Evangelion Proposal. It is designed as an "optical combat weapon" enshrouded by a rotating, crystal-like, multifaceted plate. It absorbs and stores electromagnetic energy, which it can then convert and use in attacks. The converted energy is apparently released through the core-like orbs on either end of its symmetrical body. It may have been inspiration for the angel Ramiel
