Super Power Island is the 5th island on Poptropica, featuring villains mutated by a meteor. They now have super powers and are wrecking havoc on the city, and it's your job to stop them before it's too late!
When a meteor crashed into the side of County Prison, 6 super-powered villains escape and wreck havoc all over the island. You are the island's new superhero since the old one is retired. So, you must stop them to save Poptropica.
- It is the first island to have more than one villain.
