In the World of Balance, a powerful enemy called the Intangir can be commonly found on Triangle Island. The Intangir is easily the most powerful enemy in the World of Balance - it begins every battle in Sleep and Invisible status, thus making physical attacks miss. If struck with a spell to remove Invisible, the Intangir awakens and will attack the party with Meteor, then put itself back to sleep, which also restores Invisible status.
In the World of Ruin, Triangle Island is the home of the Zone Eater, a giant worm that can eat party members. If all four party members are eaten, they surface in the Zone Eater's Belly. Surviving the various traps in the area allows the player to recruit the optional character Gogo.
