In the aftermath of the Second Impact, Gehirn initiated Project E, which culminated in the enigmatic creation of the Evangelions. Initially touted as versatile weapons designed to thwart the Angel threat and stave off the imminent Third Impact, these units concealed a deeper purpose—to harness the power of Adam, the ancient Seed of Life responsible for birthing the Angels. A hidden facet of Seele's Human Instrumentality Project, these mechas were intended to propel humanity's evolution.
Incredibly, you possess a distinct bond with one of these Eva unit, affording you the ability to summon your Eva at will and disperse it when not needed. At the heart of your Eva's structure lies a Nascent S2 Engine, the source of its formidable power. This engine can sustain your Eva in its primary operational mode, though caution is warranted, as the unit could potentially consume more energy than the engine can generate if it were to rapidly use it's stronger equipments, or if it were to go berserk.
Moreover, your Eva possesses an incredibly powerful AT-Field, a protective barrier that envelops it's physical body. This field not only shields your Eva from harm but also grants the ability to subtly warp reality around it, allowing it to attack against esoteric beings, through directly damaging their soul, making it an extraordinary asset against otherworldly adversaries.
Furthermore, your Eva possesses the remarkable capacity to materialize any human-crafted Eva equipment showcased in the Neon Genesis Evangelion series. A wide array of armaments and enhancements, all at your disposal, from positron rifles capable of piercing through the toughest Angel defenses, to the basic but versatile progressive knives for close-quarter combat.
