Let me quote something: sometimes when the last name lasts on -os e.x. Papadopoulos, then it mean the character is male.
The female of Papadopoulos is Papadopoulou (it last on -ou). So the female of Metropoulos is Metropoulou and so
on.
Here are some last names from me:
Vasilopoulou, Ashmakopoulou, Koustourakh, Karapatea...
Next time I'll give ya more cool last names, cause lots of them I know don't sound so good for a cartoon.
PS: Have you seen the american version of Godzilla? If so, then maybe you remember a character which has greek last
name: Tatopoulos.
What is "normal", anyway? If you aren't troubling the rest of the world, then there's no harm in being
abnormal.
