One of the major character-design differences between the faces of Emp and Ninjette is the fact that Emp rocks notably Big, Pouty Lips, while Ninjette sports a thin-lipped mouth sometimes described (rather uncharitably) as "froglike". Er, well, except for the occasional random image such as the profile shot in panel 2, where I suddenly slap Soupcoolers Gigantes on poor Ninjette to make her "WTF?!" reaction all the more "WTF?!"-ier. I try to avoid this blunder nowadays, but Surprised, Suddenly Big-Lipped Ninjette recurs (usually in profile) a few times through the subsequent volumes. Oops!
