Well, let's see.
Charity is an enormous green blimp-like entity that floats along through the air, showering the land below with man-sized killer plants. It also breathes fire.
Patience is a digger, slowly working it's way toward it's goal in such a way that it's very, very hard to detect. It's hands are like shovels, and it's body is large, rounded, and jiggles a bit as it moves.
Lust, as mentioned previously, is just a big, muscular, veiny humanoid with a gigantic drill on his crotch. His entire intention is to target the Evas, lumbering in close, grabbing them, and.... doing things which are not fit to describe on a blue board. I know the design's just about the most simplistic thing ever, but it's not a complex angel.
Wrath is a snake-like creature that is filled, from mouth to tail, with turbines. It wriggles and writes through the air constantly, making it very hard to actually hit. It is also plenty large enough to suck in aircraft.
