Sharp-kun: Random trivia: In Super Robot Wars MX, there's a great moment where Vega (Gear Senshi Dendoh) stands in for Misato when EVA-01 launches. ^^
Vega: EVA Unit-01, LAUNCH!!
Shinji: Yes ma'am!
Vega: …well, how about it? Do I sound enough like her?
Shinji: V… Vega-san!?
Reichu: No! It's the "U" word!!! I avoid this evil term as much as possible by using "EVA-##" as the English equivalent of "#gouki". (At least, as often as humanly possible.)
Sharp-kun: "Unit" can be used to refer to many things, including people (soldiers, for example), so I don't see any real issues with it. :P
Reichu: Watch "Beavis & Butt-Head Do America", and you will understand.
