JRPGs have some of the most iconic fights in gaming, and while most are manageable, there are always a few in each game that give gamers chills when they’re brought up.

Often, they aren’t even the final boss battles, which means you’ll get plenty of challenges throughout the game as well.

We’re going to check out a bunch of fights that made you consider throwing your controller at least a few times, and these can be main story bosses or the optional super bosses you can find in most JRPGs.

10 Seymour Flux

Final Fantasy 10

Final Fantasy X is one of the best in the genre and has a ton of fights that are both thrilling and challenging.

The one that stands out all these years later, though, is the one with Seymour Flux. The final boss of the game is a bit of a joke compared to him.

This fight is brutal for so many reasons; from his extensive HP to the tricky spells he casts, it’s just an all-around nightmare to navigate.

He comes along in the second half of the game and really, out of nowhere, ascends the side of a cliff on Mount Gagazet, and immediately, it’s boss time.

You’ve fought Seymour already at this point in the game, but trust me, you won’t be ready for what he’s got in store here.

Seymour uses an attack that causes Zombie multiple times throughout the fight, making curatives a big time issue to use, and has several massively damaging attacks, such as Total Annihilation, which does exactly what it sounds like it does.

There are also 3 phases to this fight, and though you’ll have a healthy arsenal by the time you get to it, it will still be a hell of a battle unless you know exactly what you’re in for.

9 Deus

Xenogears

Xenogears is by no means an easy game, but damn, that final fight against Deus is a trip that is brutal to play through in every way.

The fight against Deus has some optional parts to it, and those will help determine how well you do in the main fight against Deus itself.

This is the de facto final boss of the game, although another fight does come after it. Passing this one is the real test of everything you’ve learned throughout the game.

You can interact with the various orbs in the preparation area to fight different parts of Deus, and doing so will take away certain attacks or healing abilities, which is very useful.

The issue is that with each fight, you’re using more and more fuel. Taking away the abilities of the final boss is cool and all, but what happens when you arrive at the final fight with barely anything left in the tank?

Unfortunately, the fight is all done in your gears, and without enough fuel to fight, you’ll be stuck spending many of your turns charging to try and must up the fuel to pull off some consistent attacks.

It doesn’t help that Deus has an enormous HP amount and hits like a truck, and often hits all party members at once.

Unless you’ve looked up specific guides on how to max out characters with items and whatnot, this fight is a game-ender, as leaving to grind some more or go back and get additional materials will erase hours of progress, and at that point, just watch a YouTube video of the ending.

While Xenogears is an awesome time, its penultimate battle is brutally difficult to overcome.

8 Miguel

Chrono Cross

Chrono Cross has many memorable fights, but none stand out more than the fight against Miguel.

He’s an important figure in the story, especially to the main character, Serge, and he’s one hell of a fighter.

You’ll find him in the Dead Sea, which is a wild, futuristic land that time has forgotten, and the atmosphere is as chilling as the fights that take place inside.

Despite the unassuming appearance of glasses and overalls, Miguel is a demon on the battlefield.

He peppers the party with powerful magic throughout the fight, and each of his melee combos absolutely levels whoever is unfortunate enough to get caught in his path.

If you manage to stave off the melee attacks and the marriage barrage, he’s also got a special ability called the Holy Dragon Sword

This thing absolutely eviscerates you, and with you in control of Lynx at this point in the story, you better make sure you’ve got as much physical and Anti-White protection as possible because it can one-shot you if you’re not careful.

Miguel will also buff himself and debuff you throughout the fight, followed by something you’re weak to.

You’ll find yourself going through this one a few times to see it to completion, and when you finally beat him, you’re treated to one of the more amazing views in the game, even if the mood grows incredibly sad as the last remnants of Serge’s past drift away.

7 Sephiroth

Kingdom Hearts

Sephiroth is one of the most iconic villains of all time, and he happened to wander into Kingdom Hearts in 2002 and strike fear into anyone who made it to the Platinum Cup in the optional tournament that the game provided.

It’s an optional fight for sure, but for those who are seeking out the ultimate challenge, you’ll have to fight your way through gauntlets of enemies and bosses to get there. Once you do, it’s go time with the baddest of the bad.

As soon as the fight starts, One Winged Angel starts playing, and you know you’re in for it.

As soon as the fight starts, trouble begins as Sephiroth can level your HP immediately with a single attack, and you’ll need to heal quickly to even have a prayer at surviving.

Once you get your bearings, it’s still hell as his attacks demand lightning-quick reflexes to block, and you’ll also have to consider the ridiculous length of his sword strikes while attempting to dodge anything and his insane attacks like Sin Harvest, Supernova, and teleporting strikes.

Parry’s timing is crucial, but so is reading his movements, healing at the right time, and having a healthy amount of Elixirs on hand. In a game filled with massive challenges, this one is easily the toughest and far more difficult than the final boss, Ansem.

6 Ganabelt

Tales of Arise

Tales of Arise helped bring the JRPG back into the forefront in a big way in 2021. It’s arguably the most important game in the series and easily the best-selling one.

One thing it brought was an immense challenge. There are so many fights in the game that will take multiple efforts, but the standout happens relatively early on in the game against the intimidating Ganabelt.

The surrounding intrigue is a mystery, and the environment you fight him in, a snow-covered idyllic city, is a perfect place for this fight.

He’s a great early villain, and the battle with him is off-the-wall nuts. You’ll be pelted with massive, area-spanning attacks throughout the fight, and the battle itself is hard to even keep track of due to the myriad of visual effects that are happening on screen.

He wields some wildly powerful spells, and hits like a truck and, due to the relatively early point of the game you’re likely at, great equipment and attacks are probably low on supply.

Getting his health down is tough enough, but if you manage to get to that point, a countdown starts that is basically a DPS check and if you fail, it’s game over. Instantly. No second chance.

It’s a brutal end to the fight that you simply can’t be ready for without some prior knowledge, and even with that, it’s still a panic-inducing race to the finish line.

5 Ruby Weapon

Final Fantasy VII

Final Fantasy VII is a legendary game, and while the final boss is nothing to scoff at, the optional bosses of the game are even tougher. One of those bosses is the Ruby Weapon, and it’s one of the most iconic and brutal fights in the series for good reason.

Ruby is found poking its head out in the desert around the Saucer, and if you bump it with your airship, you’re in for the hardest fight of the 1990s. One that is far tougher than the final battle against Sephiroth.

The fight starts with Ruby Weapon eliminating one of your party members, and it doesn’t get much more fun from there.

Ruby has enormously damaging attacks and can whip out the Whirlsand attack at any given point to shrink your party size further.

This fight is basically a race against time and a test to see how well you understand the materia system.

You’ll need all different kinds of multi-hitting attacks, strong summons, and hugely damaging Materia spells, and know how to cast them promptly here.

The good part is if you screw up, this fight is over in the blink of an eye. It’s that tough, but if you figure out the right combination of everything, getting past Ruby Weapon is a badge of honor that JRPG gamers hold in high regard.

4 Minerva

Final Fantasy VII: Crisis Core Reunion

Final Fantasy VII: Crisis Core Reunion has some incredibly tough fights throughout, but the hardest fight of the game isn’t even the final boss.

That title goes to Minerva, the game’s most difficult-to-access super boss that lives up to that category in so many ways.

She dwarfs the final boss of the game in many ways and is only recommended for players who are heavily leveled and have top-of-the-line materials and abilities, and even then, you’re going to be at a disadvantage.

10 million HP, almost infinite MP, and a lot of pain to inflict. It’s almost impossible to avoid getting killed here multiple times.

In order to have any kind of chance against her, you’ve got to break the damage limit of 9,999, which takes enough work to accomplish on its own.

Then you’ll have to deal with her attacks that can do 99,999 damage to you, which, if you don’t dodge, is game over.

To have a shot at winning, you’ll need abilities like re-raise, tons of Phoenix Downs, Costly Punch, and her variety of debuffs, such as her ultimate attack, which will remove the Reraise ability from you.

It’s a nightmare that can take an hour to finish, and it’s one of the hardest fights any game has ever had.

3 Faust

Legend of Dragoon

Legend of Dragoon is one of the hidden gems of the gaming world, and it has some truly epic fights throughout. The final boss of the game poses a decent challenge, but the hardest of all is one that most don’t seek out.

The fight against Melbu Frahma’s right-hand man, Faust, requires a heavy dose of good equipment to survive.

The battle itself is somewhat of a puzzle, as figuring out when to attack vs. defend and what the correct magic to use will be is as tricky as dealing with the heavily damaging magic attacks he has.

You’ll also be dealing with the fact that Faust uses magic of the same element as whoever attacked him, so you’ll need a way to counter that as well.

There is a reason it’s optional, but if you choose to fight Faust, just know you’re going up against the game’s toughest challenge.

2 Melfice

Grandia 2

Grandia 2 is one of the PS2’s best JRPGs, and one of the biggest payoffs in the game is the fight against your long-lost brother, Melfice.

Stupid name aside, Melfice is as tough a boss as there is in the game and proves to be far more of a challenge than the final boss. It serves as quite the skill check for players who may have been cruising through the game until that point.

The battle takes place around the mid-way point of the game and has heavy story implications as well.

You’ve got to keep track of several things in this fight. First, Melfice’s attacks are all incredibly powerful.

Then you’ve got to worry about the three separate targets in the fight: Melfice, his sword, and the regenerator.

His attacks can rip you apart, and even if he’s not using attacks like Demon Horde Slash, his normal attacks can still do a tremendous amount of damage.

The key to the fight is focusing only on Melfice to make the fight end as fast as possible.

It’s easier said than done, however, so make sure you’ve grinded a good amount before the game and have some powerful magic ready for this battle.

It happens around the mid-point of the game and is a bit of a shock with its difficulty and represents a roadblock for many players.

1 The Immortal One

Lost Odyssey

Lost Odyssey is what many call the true Final Fantasy 13, and it came packed with challenging fights and the super bosses the series had become known for.

While the Final boss is no pushover, the game’s toughest test takes place in a side quest that wouldn’t suggest such a boss awaiting at the end of it.

The toughest is against The Immortal One, which is by far the longest fight in the game and will test every bit of your ability and understanding of the game’s systems to overcome.

It’s the final boss of the Backyard side quest, and while his placement is pretty bizarre, the fight is quite challenging.

With an outrageous health pool, you’re going to be in for one long slog against this creepy-looking boss.

The trickiest part of the fight is that there is no trick to it. It’s a war of attrition.

Black Magic does nothing to him. He has several attacks that decimate the party all at once and a nasty move called Cube that decreases the health of your party by 1 to 2 percent.

Worse, it can use this attack multiple times, and you’ll have to have a host of damaging abilities up your sleeve if you hope to overcome this challenge.

It’s optional for a reason; if this was required, few people would ever finish this game. Immortal One is easily more difficult than any boss in the game, including the final boss.
