Super Smash Bros. Great Fray was notable for having more bosses than even Super Smash Bros. for 3DS/Wii U or even Super Smash Bros. Brawl, as well as more enemies than the mentioned games. Most enemies are even weaker compared to Super Smash Bros. for 3DS's Smash Run and strong enemies will side with the player shall he/she make enough damage on that enemy.
Bosses had categorized into three types; Stage Bosses, Assist Bosses and Boss Fighters.
- Stage Bosses: Traditional bosses that appears only in specific stages. Unlike in other Super Smash Bros. games, he/she/they will only appear if the respective stage is turned into Boss Version.
- Assist Bosses: Summoned from Assist Trophy or Poke Ball, it will help the summoner to defeat the opponents, but will sides with the attacker shall the latter one deliver enough damage. Unlike regular assistants and Pokemon, Assist Bosses will only stay until he/she got defeated.
- Boss Fighters: Substitute the breaker of the seal until he/she got defeated. They are considerably more mobile than most Assist Bosses does to being able to do everything a normal Fighter can do, including Final Smashes and Great Fray.
The Legend of Zelda
|One of the big bad bosses Mario had faced. Introduced in Super Mario Sunshine, Petey Piranha is a powerful, beastly plant, and is also stronger than even Bowser or Ganondorf (in term of strength for the latter one). Watch out for his goop attacks!||
|One of the recurring The Legend of Zelda bosses, and had a thick and tough armor that most attacks cannot go through. Queen Gohma is fairly quick, and her shield is among the most durable, even when compared to Porky's. However, she takes more damage when getting hit on her eye.||Fierce Armor|
Queen Gohma's armor is so solid and thick that she never flinches until she reaches 100%. She also becomes faster, but also fall a bit faster.
|A tough leader who do really living up with being King of the Snowmads. He uses his horn to spit out icy spikes, and he the second fastest but also the most agile, which make him a truly brutal walrus! Brace yourself when he is coming through!||Ice Dragon Master|
He enlarge himself and his horn as well as able to enhance his Special Move in a phenomenal way. For instance, whatever his Neutral Special Move is, he also fires an Ice Dragon out of his horn! Freezing!
|How could Groudon be a Boss Fighter!? Well, that role would live up against appearing only as a trophy in Super Smash Bros. for 3DS/Wii U. Being the absolute heaviest Boss Fighter of them all (a mindblowing damage percentage of 135% is best to get rid of that monstrous Pokemon!) and just one forward Smash is slow but a guaranteed knockout to even the other Boss Fighters...except another Groudon!||Primal Groudon|
Groudon grabs its Red Orb, which Primal Reverse it into Primal Groudon, a bigger, heavier and obviously more powerful. This will take 200% this time for a real K.O. against that beast! Oh, and its Special Moves are more powerful, too.
|Also known as UB-05 Gluttony, this Ultra Beast had the best endurance among bosses, surpassing Groudon in term of resistance, but not as heavy. With that said, Guzzlord can eat a lot of incomings projectiles, including explosives which don't even harm it, with Crunch, and its other attacks cover a lot of areas, making it a beast of area control.||
|Ridley is too big to be a Boss Fighter? Don't get started with that. Anyway. Ridley is the fastest in term of ground speed but is more skilled in aerial battle than on ground battle. He is a bit more of a Light-Weighted compared to the other Boss Fighters, but his ability can make him a merciless foe to anyone on his way.||Meta-Ridley|
The even more vicious version of Ridley. Stronger and more resistant, Meta-Ridley becomes a nightmare machine, although this also limits his ground capacity very much.
|Apparently, the Smash Energy had somehow allowed him to get up. That's right, its King Hippo, one of the most iconic opponents of the Punch-Out series. He is surprisingly the second most heaviest Boss Fighter (next is the Heaviest Pokemon of all seven Game Freak generations, Groudon) and have a dangeous amount of Super Armor. Too bad that he fall fast. Unfortunately for you, he cannot be grabbed until he reaches 100%.||Fruit Frenzy Hippo|
He eat a lot of fruits! This not only heal half of his damage (which suggest you to hurry up and not letting this from happening) and his speed and attack are greatly boosted. If he catches you, please never let him break your shield!
|Ness' naughty neighbor yesterday, omnicidal tyrant today. His robotic mech takes less damage than the others, but his attacks can be easily avoided if you know how his attacks works. His shield is as durable as Queen Gohma's, and his Porky-Bombs can hurt anyone, including himself.||Demonic Spider Mech|
Porky's mech becomes even more spider-like, and his Special Moves are even more performant, as well as more launching reisstance. The problem is, now that he got exposed, he could also receive even more damage shall Porky himself get hit!
|This is the most despicable Mechon you will ever meet! In a good way, of course. Tied with Medusa, he may be the tallest Boss Fighter (slightly more than the towering Primal Groudon, the Great Fray of Groudon itself) and thus have greatest range but also easiest to hit, but he also never flinches from standard attacks and weak Special Moves, forcing you to knock him over with clever Aerial Attack assaults.||Black Face|
He is now more mobile and more dangerous, and his technical Special Moves can causes more destruction to everyone and himself alike! Don't get too reckless when using him!
|Queen of the Underworld. Just like Metal Face, she is the tallest Boss Fighter, although she rely more on her Special Moves than Metal Face's brutal claws and mechanism. This could want her to take distance from you, but thankfully, she is one of the lightest weighted Boss Fighters! Just don't let her petrify you!||True Medusa|
This is her true form...and a terrifying one at that. Her Special Moves are more trickier, without mentioning her more damaging Smash Attacks. However, she is also more light-weighted, even a bit more than Marx, so maneuver when playing as her.
One of the almighty final bosses from the Kirby series. Marx is the one who deceived Kirby by pushing out of his way and demend the Galactic Nova, as a wish, to conquer Pop Star. This troublemaker becomes even more troublesome, with rapid Super Smash charges, even more unpredictable actions, and medium weight despite being smaller than the others, and yet he also have the greatest range!
The crazed and insanely powerful version of Marx. He is faster, stronger, and take less damage, but his launch resistance does not changes. Worse still, he could even stay like this for longer every time he had successfully taunted! What a tormentor!
One of Master/Crazy Core's forms during the battle. They replaces Master Shadow and Crazy Army during their respective battle. They do look identical, we agreed, but they are also large, imposing, agile, powerful and resistant, but also have a weakness (the Core itself) which takes more damage and launching vulnerability (and even more when dizzy).
|Super Smash Hand|
The ultimate form of Master Hand/Crazy Hand, combining his Hand and Core form. This extreme Hand version is more powerful, more agile and constantly float instead of falling! The true way to get rid of them is to rack them up damage, and then wait for them to attack, dodge and unleash your powerful attack! Their attacks are also greatly different from their Master/Crazy Fighter counterpart, so you need practice on using this Great Fray.
Bosses' Threat Level
This demonstrate if the Boss is as threatening as it looks or actually not too much of a threat. The bosses are tiered based on exactly how dangerous are they and other aspects, such as how many damage it will take in general before being launched off screen in Final Destination or if it is a Stage Boss, on their own stage. From top to bottom, Terrifying is the most dangerous, while Threatening is the least.
This version is the widely accepted one by the Smash community, under condition of using only default moves and no equipment (or Custom Orbs for the Assist and Stage Bosses' case), as well as tested with every fighter available, including Boss Fighters themselves, to determinate how exactly dreaded the specific Boss Fighter is. In Marx and Master/Crazy Fighter's case, they were difficult to unlock and as such as the Threat Level is revealed, mod-authorized players will test them in order to be sure, before finally given a respective level at several weeks later.
The current most dangerous Boss Fighter is Master Fighter (and its palette swap Crazy Fighter), does to their high overall stats such as strength and weight, as well as powerful and versatile Special Moves.
