No, he was a hero from Greek mythology.
You can't sum up all of Roman Mythology into a single story with one hero and one villain.
In Greek mythology, cyclops is a large 1 eyed beast. Yes, he is a villain.
It's Chinese so they have different beliefs about stuff
The true villain, who is using you to acquire the powerful totems from the villain dreams, is Dr. Jupiter, or as he is better known, Zeus, the power-hungry god of Mythology Island. Once you have given him the totems, he tries to take control of Poptropica and you have to stop him (as many players did previously on Mythology Island). The battles are very similar, but a little shorter.
Chinese has a different mythology. There are many gods. It's a mix of Taoism and Buddhism. The head of the gods is the Jade Emperor!
One of the villians in Greek mythology is Cronos.
