Evangelion Unit-01:
Unit-07 (Rand's Eva) was made up for this fanfic (in the original series, Unit-07 was one of the Mass-Produced Evas, and if you thought normal Evas were creepy, you haven't seen anything yet.) Just imagine Unit-01, except gold and orange instead of purple and green, and with two horns going backwards from the back of its head, instead of one horn at the front.
Frank Stevens is an OC, and thus, while most OCs aren't included here, he has a pretty important role in this fanfic, so he's getting included anyway. As to what he looks like, he's about six feet tall, Caucasian, has platinum blond hair that he wears in a ponytail, and green eyes, as well as a (beard-only) goatee.
