Most decks in a duel try to bring out Boss Monsters, which often require multiple materials to make but have strong stats and effects once they are on the field.
Every card in a good deck is useful.
And you should always have good ways to fight and ways to stop your opponent.
These can be any type of monster, from link to synchro, and there are many different kinds.
Many of the best ones cancel out the other player’s moves and have built-in defenses to make them harder to beat.
But there are hundreds of card types and styles to choose from, so which aces are the best?
Even if you have a great deck, it won’t mean much if you don’t have a great boss monster. But maybe you don’t even know where to begin.
Well, in this list, I’ll show you how to fix that by naming some of the best boss monsters in all of Yu-Gi-Oh!
15. Virtual World Kyubi – Shenshen
Virtual Worlds are a competitive theme, but Shenshen can be used in any deck that can tune into level 9 synchros.
Shenshen has a good ATK of 2800, but that’s not all. He also gets rid of any card that is sent from the field to the graveyard.
This also affects you, but by the time you play Shenshen, your combo will probably be almost over, so you won’t usually care.
Shenshen can also return a banished card to the graveyard once per turn when your monster hits.
If you banish two monsters with different types and attributes, you can bring him back to life after he’s been destroyed.
Shenshen is pretty much going to keep coming back until he himself is sent away.
14. Accesscode Talker
Accesscode is the other best link-4 in the game. It takes two or more monsters with effects that add to link four. He stops opponents from responding to his own effects, which is a rare and useful defense.
When link summoned, he can gain attack equal to the link rating times 1000 of the monster used to summon him, on top of his base 2300 attack.
Unlike Apollousa, you want to link climb here, so 5300 attack is more than possible.
Accesscode can then send a link monster from your field or graveyard to the graveyard to destroy an opponent’s card.
You can use this effect more than once per turn as long as you choose monsters with different traits. Since it doesn’t target, it can get around some defenses.
13. Apollousa, Bow of the Goddess
Apollousa is hard to call up because you need two or more things with different names that add up to four.
Most of the time, you’ll want to use four monsters because Apollousa’s ATK is her number of materials times 800, or 3200 with four.
From there, she can cancel out and destroy monster effects by giving up 800 ATK. This can stop enemy combos totally.
Also, this effect only happens once per chain, not once per turn. This means that she can often get rid of more than one card in one round.
12. Invoked Mechaba
Since invoked cards can be used in so many decks, they have been a threat in professional Yu-Gi-Oh! for a long time.
This is one of the best Invoked monsters.
Invoked Mechaba is a dangerous Fusion monster with 2500 ATK/2100 DEF and a great negation ability.
When a Spell/Trap or monster effect is used, you can send a card of the same type from your hand to the Graveyard once per turn to cancel it and get rid of it.
If this card is on the field early, it can be hard to play around it because many decks stop working when their cards are eaten by the banish pile.
11. Borreload Dragon
Many strong monsters can only be used if you build your deck around them.
But this card is so strong because it can be used in almost every deck in the game.
Borreload Dragon is a Link-4 monster with 3000 ATK. Monster effects can’t be used to target it. This monster also has a quick effect that lets you lower a monster’s ATK/DEF by 500.
But the best part is that if this card strikes, you can take control of the monster it was going to attack at the start of the damage step.
During the end step of the next turn, that monster will be sent to the Graveyard. But until then, there’s nothing stopping you from using it as material.
10. Borrelsword Dragon
If you liked Borreload Dragon, you’ll love Borreload Dragon’s more aggressive version.
Let me tell you about Borrelsword Dragon.
This monster is just as easy to call as the Borreload Dragon, has the same 3000 ATK, and can’t be killed in battle.
Borrelsword Dragon can change a monster on the field to defense position and attack twice with a quick effect.
Your opponent also can’t do anything in answer to this. So if you say you’re going to attack, it will happen!
If this monster strikes a monster that is facing up, it can add half of that monster’s attack to its own.
9. Eldlich The Golden Lord
Many of the cards on this list are very strong. But they will never come back.
But this monster can come back again and again, and it will be a threat the whole time.
Eldlich The Golden Lord is a Zombie Monster with 2500 ATK and 2800 DEF. And, as you might expect from its type, it is very at home in the Graveyard.
You can send this card and a Spell or Trap you control to the Graveyard to send any card on the field to the Graveyard.
This is a smart way to get rid of cards that can’t be destroyed by effects.
When this card is in the Graveyard, you can send a Spell or Trap there to bring it back to your hand, and then you can use a Zombie from your hand to do a special call.
So, yes, this card will be seen a lot by your opponent.
8. Infinitrack Fortress Megaclops
This is almost impossible to get rid of if your opponent doesn’t use XYZ monsters.
Infinitrack Fortress Megaclops is a Link-3 card, but it can only be made with XYZ monsters.
This monster is a powerhouse with 4000 ATK, and it can’t be killed in battle or by a monster effect unless it’s an XYZ monster.
Megaclops, Infinitrack Fortress, also has a nasty stealing effect that lets you bring back an XYZ monster from your graveyard by using one of your opponent’s monsters as material.
If you use this ability, the damage your opponent takes that turn is cut in half.
But if it wasn’t broken, this card wouldn’t work at all.
7. Blue-Eyes Chaos MAX Dragon
If you don’t have a Blue-Eyes deck, it’s a little hard to call this monster.
But it is so strong that it deserves to be on this list.
Blue-Eyes Chaos MAX Dragon is a Ritual Monster with 4000 ATK and 0 DEF. It can’t be destroyed and can’t be attacked, so it’s very hard to get rid of.
If that wasn’t enough, this card also gives monsters in defense position double cutting damage. So unless your opponent has just given up, they can’t hide in defense mode.
I can’t say I blame them.
6. Black Luster Soldier – Soldier Of Chaos
If you banish your opponent’s key cards, most decks can’t play from the Banish pile, making it impossible for them to win.
When you add that to the fact that it is immune to powers that destroy things, you have everything you need for a great boss monster.
Soldier of Chaos – Black Luster Soldier is a Link-3 with 3000 ATK. But card effects can’t kill a monster that was used as Link Material and has LVL7 or more.
In fact, you can’t even aim at it.
You can choose from a few different results when this card kills a monster in battle:
The Black Luster Soldier can get an extra 1500 ATK, attack twice on your next turn, or get rid of a card from the field.
5. Shaddoll Construct
This monster was once on the Yu-Gi-Oh! Ban list.
As of this writing, it is no longer on the list, but it is still a big problem for even the best teams in the game.
Shaddoll Construct is a 2800 ATK/2500 DEF Fusion monster.
But its ATK might as well be infinite, since if it fights a special-summoned monster, it kills it right away, before damage is calculated.
Shaddoll Construct can be thrown at almost anything to get rid of it.
Maybe that time on the banned list was a good thing.
4. Mekk-Knight Crusadia Avramax
How would it feel to be able to beat any monster, no matter how strong it is?
Mekk-Knight Crusadia Avramax is a Link-4 monster with 3000 ATK that is very dangerous.
It also gives your whole field a lot of defense because your opponent can’t use effects on it. Instead, they can only attack it.
The best part is that if this monster fights a special summoned monster once per battle, it gets an attack value equal to the monster it is fighting, so it will always win.
If your opponent gets rid of this monster, you can also put one card from the field back into the deck.
So you can play with a great removing effect and also get the last laugh.
3. Ultimate Conductor Tyranno
There’s a reason why so many professional games are played with dinosaur decks.
And that reason is very strong!
Ultimate Conductor Tyranno has an amazing 3500 ATK/3200 DEF, and it’s easy to get him out of the Graveyard—all it takes is getting rid of two dinosaurs.
You can destroy one of your own monsters once per turn to make all of your opponent’s monsters defend face down.
This card can attack all of your opponent’s monsters during the battle phase. For each defensive position monster it attacks, you deal 1000 burn damage.
Oh, I forgot to add that it also kills any monster in defense position, no matter how high their DEF is.
You can’t get away from the king of dinosaurs.
2. Divine Arsenal AA-Zeus – Sky Thunder
At the time of writing, this card is one that people want and that costs a lot.
But if you use XYZ monsters, this is a very dangerous card to have in your Extra Deck.
Divine Arsenal AA-Zeus – Sky Thunder is an LVL12 XYZ monster with 3000 ATK and 3000 DEF. It’s also easy to summon, since you can use any of your XYZ monsters that fought this turn as material.
And if you take away two materials, every other card goes to the graveyard.
You did read that correctly.
A total clean-up!
The best thing about this card is that when your opponent removes one of your cards, it gives you that material back.
So, if they don’t deal with this monster first (which is hard, given that it wipes the field), you can hit them again and again with this effect.
1. Red-Eyes Dark Dragoon
Red-Eyes Dark Dragoon is so strong that the OCG (Yu-Gi-Oh! in Japan) has already banned it.
And it shows how scary boss monsters should be in the future.
The Red-Eyes Dark Dragoon is a Fusion monster with 3000 ATK/2500 DEF and a long list of powers.
This monster can’t be destroyed or targeted by powers that do that. So it stays on the field once it’s there.
It also has a bad effect that lets you kill a monster and deal burn damage equal to that monster’s attack once per turn.
Also, it has a quick effect that lets you throw away any card to cancel and destroy any effect card.
Some players think that Red-Eyes Dark Dragoon will finally be on the TCG Ban List, but it’s not there yet as of this writing.
But until that happens, this boss gets the top spot on this list, which he or she deserves.
