Leliel

Leliel is a reference to the Twelfth Angel from Neon Genesis Evangelion, whereas it appears to be a floating sphere with a warped, black and white color pattern. However, Leliel's real body is actually what appears to be a shadow on the ground. The manifestation of Leliel's body in our dimension is 680 meters wide but only 3 nanometers thick; the floating sphere is just the "shadow" it casts in our dimension. Because it possess an inverted A.T. Field, it can absorb any material from our dimension inside of its body, within which is a Dirac Sea.
