For those of you who haven't seen yet, the new character is the Roman emperor Nero. My theory was pretty far off, then. Also, his character design has been recolored pretty majorly. I'll add a picture here.

No, that is not 2p!Italy. His eye color, hair color, and skin tone are all those of normal Italy, which is further confirmed by his facial expression. However, there is actually another new guy who hasn't been explained, he's also in the picture. I'm fairly sure that he is another Roman emperor, though I'm not sure which one. In the latest strip, an unidentified emperor is shown, and he looks pretty much just like this fellow, right down to his facial expression! All it says about him was that he had a handsome face, but he was rubbish for a few years and ended up in the Tiber. If anyone has any idea which emperor this would be, then please let me know!
