Hades

On New Year's Eve, the Poptropica creators showed a new character, Hades. He appears on Mythology Island as the ruler of the Underworld and the brother of Zeus.

Role in Mythology Island
On the events of Mythology Island, a Poptropican tried to stop Zeus from taking over Poptropica. With the help of Hercules, he entered on Poseidon's Throne and got his trident.

When Hercules moved the boulder of the Underworld, the Poptropican convinced Hades to give him his Crown, as he cannot get out of the Underworld. After the Poptropican saved Mythology Island, Hades did not reclaim the crown, however. His crown allows you to grow big anywhere.

Creator
He is one of the  Creators of Poptropica.
