With well over 50 million total hit points, Yiazmat is by far the most durable boss in
the entire Final Fantasy series, with it being physically impossible to beat the monster in less than a few hours. To put into perspective just how staggeringly powerful Yiazmat is, in order for the player to even have the chance of fighting it, they first need to beat the Hell Wyrm, which is a boss that already boasts over 8 million HP alone.
During the Yiazmat encounter within the Colosseum, players will notice that its health is so astronomically large, that its HP bar is actually split up into individual segments, each of them containing 1 million health points. Additionally, if the party somehow successfully drops Yiazmat's HP below 50%, the total damage it receives will be reduced by a quarter, and if the characters try to get out of its attack range for a breather, it will start buffing itself to become even stronger.
