Final Fantasy X – Monster Arena , how to unlock all of the fiends!

Be afraid.. be very afraid.. these guys can mess you up! Art by Rytellia

The Monster Arena is an unlockable area in the Calm Lands where you can fight fiends so supremely overpowered that there are extremely specific ways to beat some of these bosses that could honestly kick Sin’s butt. (I had more problems with some of these fiends then I did with all the final bosses combined!)

The arena is both pretty straight forward and a bit confusing all at the same time. In this post, I’ll be going through how to get each of the arena specific fiends and how to unlock the chance to kick their butts!

FUN FACT (Because fun facts are awesome): The guy you talk to at the Arena who makes the new fiends? He’s an optional boss in FFX2! Trema, the unsent with the ability to reconstitute pyreflies into stronger and more deadly versions of fiends.
