No. 3: Gabriel Unlimited / Indalecio – Star Ocean: The Second Story

Another hidden boss on our list, except that this one is also the main story’s final boss as well. After beating Star Ocean: The Second Story, players can go on and fight through a hidden dungeon with difficult battles that can cause one’s controller to suddenly fly straight into walls. It’s an interesting phenomenon. But Gabriel’s “Unlimited” form is one of the toughest in the game, on par with the Ethereal Queen hidden boss that appears in every Star Ocean. The biggest gripe against this guy is that he can move so fast that it’s almost like he’s teleporting and can cast spells almost instantly. Your best defense? Hit the level cap of 255 with all characters, deck them out in the best gear, and develop a penchant for micromanaging.
