Misato:“Evangelion Unit 01, lift off!”
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.
