Asinastra
what do you mean? do you mean like big eyebrows like amarou (FLCL) or rock lee? well i guess they made them like that so they can be recognised more easily because they have big eyebrows i mean i call amarou eyebrow man.
;0; Yay Rock Lee~~!!
*ahem*
i agree with Asinastra.
They give those "apperances" to certain characters mainly because they want the viewers to reconize the character. Everyone has a unquie feature about them, so what's so wrong with anime characters having physical features that stand out?
Also, what other's have posted (Sirious81 and Yuki), it IS the artist style. If they want to make them that way, its because they want to. Usually this leads to a more "creative/original character" and making is quite known or popular.
