The sixth of the seven Sevii Islands. A majority of Fortune Island is connected by a long water route named Water Path. Water Path connects to Ruin Valley, a large rocky area which contains Dotted Hole, a small town, and Green Path. Green Path is home to Pattern Bush, a strange pattern-made undergrowth filled with bug pokemon. On the opposite side of Green Path and Pattern Bush is Outcast Island and Altering Cave. Altough many have forgotten why it was named such, Altering Cave has an explained phenomenon that happens when certain people enter.

Fortune Island is accessible by ferry from Vermillion City, Olivine City, or any of the other Sevii Islands.
